13. FIVE DECADES OF RESEARCH WORK
1. Turbomachinery Blade Vibration –
1.1 Free Vibrations: My early research began with the determination of first bending natural frequency
of tapered cantilever blades by using fundamental energy principles. This work expanded to the coupled
bending and torsion free vibration characteristics of turbo machine blades with taper, pretwist and
asymmetry mounted on rotating blades at a stagger angle. These calculations have been extended to
packeted-blades and bladed disks etc., to determine the influence of coupling between the blades and the
neighboring elements. Various methods have been used, e.g., Variational principles such as Galerkin,
Ritz and Lagrangian procedures, Collocation, Holzer, Myklestad, Polynomial Frequency Procedures, and
Finite Element Methods. The structure is considered as a beam or pre twisted plate (shell), laminated
composite plate or as a submerged structure in a hydraulic turbine. Higher order effects such as shear
deformation, rotary inertia, fiber bending, additional effect of torsion due to pre twist, support flexibility
were also considered. This work is then extended to laminated plates. A significant part of this work has
been to include the influence of Coriolis forces and their effect on the dynamic behavior of rotating
blades. Determining the natural frequencies and mode shapes and detuning them from possible
resonances is considered to be sufficient in the design of low speed and low capacity machines. This
work was initiated in IIT Kharagpur and later under the influence of Professor William Carnegie of
University of Surrey. While these early developments helped in a clear understanding of free vibrations
that help in detuning the blades from resonance, it soon became clear that excitation and damping are
important factors that have to be addressed in an analysis for fatigue failures that have occurred in the
development of aircraft engines by Frank Whittle and the maiden voyage failures of steam turbine blade
failures of QE II passenger liner in late 1960‟s.
1.2 Stage Aerodynamics: For the first time the coupling of fluid structure interaction in determining the
forced vibration response was recognized and towards this end unsteady 2 dimensional thin airfoil
theories were developed to determine the non-steady lift and moment acting on isolated air foils due to
transverse gusts. These theories were then extended to stream wise gusts for flat plate and cambered
airfoil blades with an angle of attack. Interaction between a stator and rotor row of cascades of a turbo
machine stage was then considered and the expressions for transverse and stream wise gusts induced as a
result of potential flow and vortex wake cutting were developed. Using these, general purpose computer
codes were developed to determine the non-steady forces of a given stage. The theories are then extended
to compressible subsonic flow and today the most efficient computer codes for gas turbine stages are in
operation in an interactive mode on work machines. This approach was developed in Wehle Research
Laboratory of Rochester Institute of Technology with preliminary discussions from Professor Sears of
Ithaca after his retirement and settlement in Arizona for US Naval Laboratory requirements as a part of
lifing of turbomachine blades.
1.3 Hydraulic Analogies: To study the flow visualization and determine the non-steady forces of a turbo
machine stage, hydraulic analogy was considered as a possible tool. As there was a major limitation with
the classical analogy for the specific heat ratio, exact modified analogies were first derived and shown to
be accurate through several analytical studies of axisymmetric nozzle flows. The limitations on classical
and modified analogies due to the presence of a straight or oblique shock have also been studied and
verified by experiments. The modified analogy is now well established. This test was developed in Stress
19 Dr. J.S. Rao
Technology Inc., Rochester for US Naval Laboratories for flow visualization, determining the ratio of
unsteady forces to steady forces leading to life estimation. Using this analogy, rotating water tables are
designed to simulate turbine stages and determine non steady forces and make flow visualization studies.
Flat plates and cambered plates were initially tested and then the stage of an Orpheus engine has been
successfully modeled. Subsequently GTX engine (aircraft engine under development at Gas Turbine
Research Establishment, Bangalore) turbine and compressor stages were modeled to determine the non-
steady forces. For the compressor stage, the flow visualization studies have shown the conditions under
which rotating stall could occur. The development of modified hydraulic analogy was used to model the
GTX engine combustion chamber and study the flow visualization and pressure ratios obtained in the
chamber. Studies on this have been successfully completed.
1.4 Damping Tests: The application of the non-steady force and moment data on the turbine blade leads
to the assessment of forced vibration response. In this calculation the most important parameter is the
damping. Tests have been conducted through several rigs for this purpose. Equivalent viscous damping
measurements made on rigs where the centrifugal load is simulated by thermal cooling or in actual spin
rigs are used to determine the response of turbo machine balding. At some resonances the errors have
been found to be of the order of 400 %. These models were therefore discarded and search began to
quantify the nonlinear damping more thoroughly. Today damping models dependent on rotational speed,
mode and strain amplitudes are developed and application of such models has shown that the resonant
stresses can be determined with an accuracy of 30 %. This has been a significant breakthrough in the
blade vibration work. Methods for determining the gas damping values due to unsteady aerodynamics in
the stage were also developed and for a typical case the self-excited vibration has been studied. A
significant advance is now made to determine the material and friction damping through finite element
models that avoid costly experimentation.
1.4 Resonant Stresses: Initially modal analysis theories were developed to determine the resonant stresses
at the critical speeds under steady operation, when any one of the blade coupled modes coincide with a
given harmonic of the nozzle passing excitation. These were then extended to the case when the rotor is
either accelerated or decelerated so that the transient resonant stresses can be determined taking into
account the nonlinear damping. These stress values are then used in developing computer codes for the
life estimation of a blade using cumulative damage and fracture mechanics theories. Some case studies
were shown when the blades can fail for certain acceleration values or over a certain number load blocks
arising out of the engine stopping and starting.
1.5 Heat Transfer: The heat transfer and temperature distribution is also important in determining the
structural response as the material data is dependent on the temperature. With the advent of very high
temperature applications of the order of 2000 deg. K and above radiation effects become pronounced. For
this purpose comprehensive finite element programs were developed taking into account the high
nonlinearities due to the radiation effect. Combined vibratory and thermal loads and the resulting
response programs were developed for this purpose.
1.6 Governing Equations of Turbine Blades: Another important factor is the maneuvering loads on blades
due to engine precession in diving and turning operations of aircraft particularly for military applications.
Equations of motion for turbine blading under such conditions have been derived and solutions of these
20 Dr. J.S. Rao
are in progress. Similarly, equations of motion of long flexible blades as in helicopter rotors have also
been derived and solutions obtained taking into account the nonlinearities due to Coriolis forces.
1.7 Fracture Mechanics: The technologies developed for life estimation have been successfully applied
in the failure investigation of Narora plant accident of 31st March 1993. Using the blade centrifugal
loads, steam bending loads and unsteady forces, the steady and dynamic stresses are determined. The
conditions at which a crack can initiate at the root are established. With the initiated crack, crack
propagation studies were made and a close match of the striation spacing of the observed fracture is
obtained. Conditions of multiple cracks that occurred in this blade failure are also studied.
1.8 Strain Based Methods: Local stress-strain approach has been successfully employed to predict
cracking behavior of Giribata hydraulic runner blades. The elasto-plastic analysis of last stage steam
turbine blades has been obtained using NISA finite element code to determine the plastic range near the
stress raiser points of the blade root. In critical areas of the blade root, it was shown that the material just
yields and the maximum stresses are well within the ultimate yield strength, which otherwise are far
beyond the ultimate strength of the material as predicted by linear analysis. The extent of plastic zone is
also shown to be such that linear elastic fracture mechanics principles can be applied.
1.9 Analytical Determination of Damping: A major problems in blade analysis has been the estimation of
damping before arriving at an accurate stress value for life estimation. A major breakthrough has been
achieved by developing an analytical procedure using commercially available codes such as ANSYS.
Lazan‟s damping law is used for each element in the bladed-disk and the energy loss is determined from
the coefficient J and exponent n for the material. Using the potential energy in each given mode, the loss
coefficient is then determined. The equivalent viscous damping factor can then be determined as a
function of reference strain value for each mode as a function of strain amplitude and speed of rotation.
In the presence of interfacial friction surfaces, free vibration decay curves are determined from impulse
response with the material damping. This method has eased life estimation of complex rotating
machinery. This procedure has been obtained to determine the life of last stage blades in reverse flow
conditions in collaboration with experimental flow data from Leeds University.
1.10 Single Crystal Blades: Recently in collaboration with Ukraine and Poland, the free vibration
characteristics of single crystal blades are determined using 3D finite elements.
1.11 In 2009 US Air flight was hit by Canadian Geese causing the aircraft to land in Manhattan River.
Wright Patterson Air force Base gave a project through European Office of Aeronautical Research Board
to India and Poland. For different blocking conditions the unsteady shock forces were estimated in the
first stage and the life was determined which was only 7 seconds.
2. Torsional Dynamics of Drive Trains –
2.1 Locomotive Crankshaft Failures: Initially the work on torsional dynamics began with the
investigations on failure of crankshafts in ZDM2 narrow gauge diesel locomotives. The excitation forces
were identified by tests on the engine in Nagpur to obtain PV diagrams and then numerically determining
the excitation torques in each of the engine orders. With the availability of computers at that time Holzer
21 Dr. J.S. Rao
table calculations were done to determine the free vibration characteristics of the engine with Suri-Mach
transmission system and the cause of resonance in the engine running speeds was shown. These engines
used without Suri-Mach transmission did not have similar problem elsewhere in the world.
2.2 Diesel Engine Drives: The expertise developed in torsional dynamics was then extended to model
diesel engine driven generator sets to determine the natural frequencies, mode shapes, resonant stresses at
the critical speeds, cyclic irregularity for the frequency quality and safety calculations according to
Lloyd's of England.
This work was then extended to model diesel electric locomotives developed in India at Chittaranjan.
The nonlinear properties of the couplings used which are functions of the torque and temperature were
considered by an iterative solution to determine the critical speeds, resonant stresses and the performance
of the couplings. These programs were then checked against tests conducted in Chittaranjan.
The performance of nonlinear couplings developed by Twyflex couplings limited in England was studied
by Ritz averaging techniques to understand the behavior of such couplings in marine and other
installations.
The subject was then applied to reciprocating machine applications to understand the dynamic behavior
of reciprocating engine compressor sets or electrical motor reciprocating compressor sets to find out the
critical speeds and resonant stresses and also the coefficient of speed fluctuations. These programs are
subsequently developed in transfer matrix form.
One of the main problems in turbo alternator sets is the design of coupling to properly isolate the turbine
from generator and effectively transmit sudden shock loads arising out of line short circuit. Programs to
develop the transient torsional stresses in a turbo alternator set were developed using continuous transfer
matrix elements.
Using the programs thus developed, the failures of gear boxes in a gas turbine power plant in Europe and
in Kancheepuram have been successfully investigated and life estimation procedures established. The
gear life estimation programs are computerized.
Finite element solutions of industrial rotors in torsional vibration through ANSYS are established taking
into account various electrical disturbances from the grids including short circuit conditions at the
generator terminals.
Practically any torsional dynamics problem in industry can be solved with the help of programs
developed above and vast experience has been gained in this field.
2.3 Complete Power Train and Drive Train Simulation of SUVs and Hybrid Cars: With the advent of
CAE, simulation of engineering design processes is gaining rapid progresses in order to reduce design
cycle time and prototype building and testing practices. An automobile drive train from engine to wheels
through a torque converter, isolator, transmission, transfer case, differentials, propeller and axle shafts, is
a typical example whose design and acceptance of prototype is an expensive and time consuming
process. It was demonstrated how this design process can be speeded up through simulation of drive train
dynamics that can match with test results; thus reducing design cycle time and gain better understanding
by parameter variation during the design stages.
3. Bending Dynamics (Rotor Dynamics) –
3.1 Crankshaft Bending Dynamics: While investigating the failures of crankshafts in ZDM2 diesel locos,
computer programs were developed using Myklestad method to determine the natural frequencies in
22 Dr. J.S. Rao
bending. The tabular methods were replaced by transfer matrix form in subsequent years and general
purpose computer codes were developed to determine the critical speeds of rotors mounted on flexible
supports.
3.2 Influence of Bearing Supports: The properties of hydrodynamic and hydrostatic bearings were
determined by solving the appropriate Reynolds equation. The effect of tilt was considered in doing so
for plain cylindrical hydrodynamic bearings. Eight coefficient bearing models were developed for
application to rotor dynamics.
Programs were developed by transfer matrix method in initial days to determine the unbalance response
of industrial rotors such as turbine, compressor and alternator rotors mounted on eight coefficient
hydrodynamic bearings.
Methods to predict instability threshold speed due to oil whirl are developed using linear theory.
Experimental tests were conducted to verify these speeds and demonstrate the oil whirl and whip of the
rotors mounted on hydrodynamic bearings.
The asymmetry of rotors such as generator rotors was taken into account in the unbalance response
programs.
Subsequently these programs were generalized to account for the bearing properties and distributed mass.
The programs were generalized to the extent that the rotor geometry is fed as data into the program and
all the modeling was done internally.
For determining the unstable operation speeds a general transient whirl program was developed based on
a time dependent transfer matrix method which itself was separately derived. This program can take into
account the bearing nonlinearities to determine the transient whirl of the rotor along its span and thus
determine whether a rotor speed is safe or not beyond the linear instability threshold speed. This program
enables the designer to push the rotor speeds well beyond the linear instability predictions.
The new generation gas turbines use a multi spool configuration with an intershaft bearing. Transfer
matrix methods for such multi spool rotors were derived to determine the unbalance response and
computer codes were developed in a very general form.
Several industrial rotors were balanced in the field and the laboratory using influence coefficient method.
Multi plane flexible rotor balance methods were developed using influence coefficient method.
For the Narora unit incident in March 31, 1993, extensive calculations have been made to determine the
critical speeds, blade loss response and bearing loss response of the Turbine and Generator units. From
these calculations, the rotor coast down chart available during the incident could be corroborated,
particularly explaining its hover at a new critical speed. These calculations also enabled the
determination of rub loads of the LP V stage and the fracture mechanics of the blade in a short span of 30
seconds.
3.3 Nonlinear Bearing and Seal Properties: Cryogenic pumps employed in Geo stationary launch
vehicles handling liquid oxygen and hydrogen are highly complex rotating machinery running at very
high speeds around 43,000 rpm. The influence of rolling element bearings, seals and couplings play a
significant role on the system dynamic behavior. The rotor and its mounted parts cannot be assumed to be
beam models and the casing is also flexible and interacts with the rotor. A complex CAD model of this
system is developed and finite element model generated for a complete dynamic analysis of solid rotors.
The Cryogenic design thus developed operated successfully in the launch of GSLV on 5th of February
2014.
23 Dr. J.S. Rao
Estimation of Seal stiffness and damping coefficients is a complex subject. The methods of using
commercial CFD codes for determining the seal performance and the stiffness and damping coefficients
is established using Fluent platform. The radial and tangential loads are estimated first from the pressure
distribution of a seal under given spin and whirl conditions with an eccentricity. These loads are shown
to be related to the stiffness and damping coefficients and procedures of arriving at them are established.
The results for zero eccentricity available from Hirs theory are shown to be in good agreement.
3.4 Gear Flexibility: In high speed turbo-alternator systems, with gear transmission units, the gear box
flexibility plays an important role in the coupling of torsional and bending dynamics. A general purpose
computer program to determine the coupled natural frequencies has been established using finite element
methods, as a part of project in Taiwan. The significance of dynamic coupling terms and application of
squeeze film dampers to control bending-torsion vibrations has been extensively studied. It is shown that
geared rotors with squeeze film dampers show chaotic behavior and the route to such chaos is
established.
3.5 Expert Systems for On-Line Diagnostics: With the above technology and vast experience several
diagnostics studies were carried out on diesel generator sets, turbine generator sets etc., with the
measurements in the field and real time analysis to understand the problem and remedy the same.
A general purpose expert system to diagnose the fault of a rotor is developed. On-line expert system was
developed to continuously monitor the condition of a rotating machine installation and give diagnostics
for an impending problem. This is the first of its kind in the world and is satisfactorily working in
Kakrapara nuclear power plant and extended to other nuclear turbines in India. A similar system is
installed in Ropar thermal power plant. The continuous condition monitoring and expert diagnostics is
extended to operate remotely through the web to enable remote maintenance of a system.
The LP rotor in Raichur thermal power plant is diagnosed to be bent and also subjected to unstable
vibrations. It was also found by analysis that the pedestal support for the bearing is eccentrically mounted
and also the platform is cantilevered giving rise to axial vibrations of the pedestal as a result of the
vertical unbalance vibrations. The instability is attributed to looseness in assembly.
3.6 Influence of Foundation: The influence of foundation on rotor dynamics is first established through
sub structuring method. Now methods of combining stationary and rotating systems through
„USERACEL‟ applications in ANSYS are established that simplify the problem. Twin spool solid rotor
problem solution methods are also established.
The performance of aircraft engines under a given unbalance is studied taking into account the casing
and test bed conditions. The results obtained are shown in some specific applications where test bed has
influence the response to be in agreement with tests.
3.7 Solid Rotor Dynamics: The rotor dynamics during the 20th century is limited to beam models
developed initially by Jeffcott in 1919. Solid rotor dynamics is first established early 21st century through
the ANSYS solver to handle twin spool rotors and casing/foundation with several support bearings and
seals to obtain Eigen values, stability, unbalance response. Nonlinearities from bearings and the resultant
effects on rotor dynamics included. Solid rotor dynamics was also successfully applied to Synchronous
generators of Crompton Greaves, Bombay. The influence of high acceleration rates are also taken into
account on the shift of critical speeds and reduction of peak amplitudes of whirl. Several works have
been contributed to OEMs in US, Canada, England, Germany, India, Hungary and Italy.

4. Railway Train Consist Dynamics
4.1 Draw Bar Failures: Studies on train consist dynamics began with the failures of draw bars observed
in the north eastern hilly region of India. The problem was formulated as a multi body system with
simple longitudinal motion and inputs at the engine. Modal analysis was used. Transient response
calculations were made by special programs developed for this purpose, arising out of train handling
conditions while encountering a steep slope upwards or downwards or suddenly responding to changes in
signals on a hilly terrain. Tests in the field were conducted to determine the type of forces felt by the first
draw bar between the engine and train and the analytical response obtained was checked against the field
results. In an actual case of deliberate draw bar failure induced in the field, the computer program
predicted very accurately the location of the failure.
These studies have been extended to lay down the train handling conditions of long train consist systems
to haul heavy goods over long distances. The draw bars are considered to be nonlinear with a slack time
and the number of degrees of freedom has been increased to three. The computer code uses time
marching numerical techniques as against the linear model considered before.
4.2 Brake Squeal Instabilities: In underground metropolitan transport systems, high speeds of travel are
achieved by using disk brakes. However these brakes are prone to instabilities. The system adopted in
Washington underground trains ran into troubles in early 80's. To understand this problem a
mathematical model of the disk, friction pads and the caliper carrying braking pressure system attached
to the truck, is developed. Equations of motion were derived for each system and various modes of the
disk obtained by ANSYS program are each structurally coupled to the pads and caliper to obtain the
system models. Using the kinematic constraint at the point of application of braking force between the
caliper, pads and the disk, stability criteria were derived. The model predicted exactly all the instability
modes detected in field tests using real time analyzers. For the purpose of tests special instrumentation
was devised for obtaining the temperature of the pads and disk and the vibratory signatures of different
elements in the brake system. The noise signatures were also analyzed in a similar manner. Five other
available systems are validated by the computer codes and two of them were chosen, one which would
squeal and the other not to squeal as predicted by the computer code for field tests. The field tests have
confirmed the computer code predictions.
5. Aircraft Engine Design –
5.1 LP Compressor of Kaveri Engine for Indian Light Combat Fighter Tejas: It has been a great
opportunity to design the LP compressor of Kaveri engine from the base line provided by Gas Turbine
Research Establishment (GTRE), Bangalore, India. The work was carried out by a team of nearly 40
engineers with continuous interaction from GTRE engineers.
5.2 Flow Analysis: CFD analysis is first performed on the primary and secondary flow paths first on the
base line to determine the heat transfer coefficients and bulk temperatures under transient as well as
steady state conditions.
The compressor performance is studied to check whether the desired pressure ratio has been achieved.
An unsteady flow path interference study is made for each stage to determine nozzle loads. These CFD
analyses are first carried out so that the base line is not disturbed.
25 Dr. J.S. Rao
Then a transient heat transfer analysis is done for the entire integrated structure to determine the thermal
stresses and expansions in all the directions. The radial expansion helps in identifying possible rub
instances.
5.3 Rotor Dynamics: A complete system rotor dynamics analysis is conducted which then identifies whirl
amplitudes at critical speeds and thus the rub conditions can be established while accounting for thermal
expansions simultaneously. Any alterations to the base line can be incorporated at this stage before
proceeding to individual component design.
Each individual component is then designed for structural integrity and life assessment is made. Two D
axi-symmetric analysis is made for the entire rotor system of the compressor with blade loads, centrifugal
loads, thermal loads … to determine peak stresses and their locations. Individual bladed disks are then
modeled using axi-symmetry with stress stiffening and spin softening effects accounted for. The peak
stresses usually occur at the dovetail locations. In some cases they are above yield.
5.4 Optimization for Minimum Weight: Strain energy density plots are obtained to identify locations
where material can be removed and where it is necessary to strengthen. DOE techniques are developed to
perform optimization for minimum weight.
5.5 Bearing Stiffness Evaluation: The bearing stiffness estimation techniques are developed by
considering the rigid body displacements as well as structural deformations. The loads are applied in the
form of cosine distribution and the displacements are Fourier transformed to be able to determine the
stiffness in an accurate manner. The support structure is then optimized by using DOE techniques.
Weight optimization is similarly carried out for the casing and stator blades and other stationary
members.
5.6 Vibration Analysis: All stages are vibration analyzed and damping is determined by using hysteresis
and Coulomb damping models developed for this purpose.
5.7 Life Estimation: The life of each blade and disk is then assessed by strain based cumulative damage
calculation.
For high pressure cooled blades transient heat transfer and thermal analysis is established to be able to
predict strain based life by using Neuberization technique. Life estimation procedures are all streamlined
and automated to minimize design cycle time. These methods include stress-based, strain based and
fracture mechanics methods.
5.8 Anti-Icing Design: Anti-icing for the front frame is accounted by providing a hot flow path to prevent
any solid object injection into the system.
5.9 Bolted Joint Design: All the bolted joints between the rotor disks and vane drums are analyzed by
using nonlinear contact elements and elasto-plastic analysis to provide optimum closure with minimum
weight. The stresses are also contained within yield.
26 Dr. J.S. Rao
5.10 Blade-Off Condition: Blade-off condition is simulated for ascertaining the structural integrity of the
casing. Also, critical off-design operating conditions are accounted in ascertaining the structural
integrity.
5.11 Mistuning Design of Bladed-Disks: Intentional mistuning design procedures are developed using
Mode distortion as a primary mechanism to study the forced response of bladed-disks and mitigate
resonance.
6. Optimization –
Optimization from commercial codes is fast becoming a reality to decrease the design or modification
cycle time for stationary and rotating structures. Industrial optimization essentially involves using shapes
as variables and solvers to obtain the objective functions. Solid Isotropic Material with Penalization
(SIMP) evolved Topology optimization that is successfully employed.
6.1 Design and Optimization: It is first shown that the optimization that evolved with Brachistochrone
problem from Isaac Newton and Design approach given by Boris Galerkin give same results and thus
Optimization itself can be used to obtain a design solution directly. This principle is applied to arrive at a
70 seater aircraft wing structure without first getting a baseline from classical approach.
6.2 Weight Optimization: Using topology optimization the weight of the wing-box central rib of a
proposed Saras aircraft can be decreased by as much as 46% by considering the severe loading
conditions. In doing this, the maximum deflections are retained of the same order and the peak stress
pushed to less than half of yield value, while the average stress is retained at the same value of the base
line. OptiStruct is used for this purpose.
This technique is used to reduce the weight of a bladed-disk of a fighter aircraft engine by providing
holes and removing material in the shank by removing the material where there is no strain energy
density; or by keeping the maximum stress below the allowable design stress at the stress raiser location.
The weight reduction is a little more than 10%.
6.3 2D Shape Optimization: In an attempt to make the bladed-disks more efficient structures, the designs
are taken into globally elastic but locally plastic structures around the vicinity of stress raiser locations,
thus making the average stress to be high. Determination of true stress in these local plastic regions is
first obtained by using Neuberization principles. The local strain here is reduced by modifying the
shapes; initially this is achieved for 2D shapes (blades without curved entry) by using topology
optimization. The design vectors are chosen from the morphed shapes within the constraints and the
objective function of local stress or strain evaluation is obtained by a solver such as Ansys used on a
platform where the preprocessing and post processing are done for the results of the solver. More than
25% of reduction in local strain could be achieved that boosted the life by as much as four times of the
baseline in operation.
6.4 Topology Optimization Design for New Wings and Flutter: NAL and ADA were engaged in design
of 70 seater aircraft and the wing was required in a short time instead of the traditional testing and
approximation route. New technology was developed to get the concept design and using dimensional
optimization technique this wing was produced in about four weeks.
A flutter analysis of this wing was also successfully analyzed and published.
27 Dr. J.S. Rao
6.5 Optimization with multiphysics objective functions: There are several applications that involve
industrial applications with multiphysics objective functions with shape functions as design variables. A
typical example is that of a Dorsal Unit having transmitters and receivers that produce heat at the same
time operating efficiently at lower temperatures. The required temperatures as objective functions are
obtained by a conjugate heat transfer of the flow that is made to carry away the heat while transferring
some through the surrounding metallic structure. A successful design of the shape of the dorsal unit is
obtained by topology optimization of its shape with conjugate heat transfer maintaining the maximum
temperature to be within allowable limits.
Another typical case is that of minimizing flow induced noise. The eddies in the turbulent flow are
modeled as sources for noise propagation by either Lighthill‟s analogy or Ffowcs Williams-Hawkings
wave equation; This approach adopting RANS approach with Large Eddy Simulation (LES) or Direct
Navier-Stokes Solution (DNS) is adopted to capture the sources and evaluating the objective function for
optimization of the shapes to give minimum noise; this has been achieved for various cases such as
Sunroof buffeting noise in an automobile
Noise levels during a launching of a space vehicle to protect the instrument bay
Minimum noise to the pilot in a fighter aircraft cockpit
6.6 Magneto hydrodynamics flows: In the recent years design of Fusion Reactors involving
electromagnetic fields as large as 107 times that of the earth‟s magnetic field are in progress; they require
Tritium (an isotope of hydrogen) breeders for the reaction chain of fusion of Deuterium and Tritium that
produce an alpha particle and a neutrino (besides energy) from which the neutrino is utilized with Liquid
Lithium Titanate (a magnetic fluid) to produce Tritium. This Breeder that faces plasma at 100 million
degrees Celsius through radiation from the vacuum vessel is also required to be cooled by Helium. To
achieve optimum design of these flows, shape optimization is used in the first such design of a Liquid
Lithium Ceramic Breeder successful.
6.7 Metamodel Based Design Optimization: One of the major problems in industrial optimization today is
the computer solver time in evaluation the objective function or functions; this maybe as much as a
month in the case of vehicle crash analysis with high speed computers. These problems being highly
nonlinear, the optimization is achieved by developing a Response Surface in a Hyper Plane of the design
variables (shape functions) using a Design of Experiments Approach (DOE) and a Metamodel (or a
Surrogate) to seek the optimum value on the Response Surface without resorting to the time consuming
Solver. This approach is successfully used in
Three Dimensional Curved Entry Roots of Last Stage Low Pressure Stage Steam Turbine blades or
Low Pressure Compressor Blades (or Fan Blades) of Aircraft Engines to decrease local strains and thus
increase life
Three Dimensional Shape optimization of Energy absorbing structural members of vehicles for
passenger safety from crash
6.8 Composite Optimization: In modern designs where weight reduction is practiced to obtain efficient
light eight structures, composites are being increasingly utilized. Such composite designs are derived
from topology optimization.
A successful design of a composite aircraft wing from an optimized metallic wing is obtained; this
allows considerable reduction of light weight aircraft with the required strength
28 Dr. J.S. Rao
The long fan blades or first stage compressor rotor blades are susceptible for failure from foreign object
ingestions such as Canadian Geese bird flock that hit US Air flight in 2009. A long blade loss
decreases considerably the life for complete failure to few seconds and the resulting engine loss can be
catastrophic for human loss. Conversion of metallic blades to composite blades decreases the impact
loads on engine casing and reduction of unbalance loads on the engine rotor dynamics. A successful
design for replacing a metallic blade by a composite is achieved by topology optimization
6.9 Temple Cart Weight Optimization: Temple Carts of ancient Rig-Vedic Designs made of wood are
very heavy, as much as 300 tons in weight. These very slow moving carts sometimes lead to serious
accidents when devotees pull them on festival days. Topology optimization is used in redesigning them
for considerable weight reduction while keeping the Vedic design principles intact.
7. Rotor Blade CFD for Marine Propulsion and Helicopters –
Hydrodynamics, open water characteristics of propellers, propellers with a cowl and the hull interaction
have all become accessible for CFD analysis using commercial codes to assess the thrust and torque
characteristics of advanced frigates and submarines. Cavitation is another phenomenon which affects
significantly the ship characteristics and can induce severe vibration and under water noise, both of
which become important in submarine navigation to avoid detection by enemy vessels. These methods
are well established now. Using Fluent platform these techniques are developed for assessment of ship
and submarine characteristics; several results obtained are verified against available experimental results
including cavitation.
CFD was successfully used in modeling helicopter rotor blades and determining the lift in designing light
weight helicopters.
8. Combustion, Flow, Instabilities in Heat Exchangers and Furnaces –
Complete Flow, Combustion, Thermo-mechanical analysis and flow induced vibrations of heat
exchangers was developed. Velocity field, pressure field, temperature field and flame analysis was
achieved in the heat generating sections. The acoustic field is also obtained. A complete vibration
analysis of the system and the mode shapes are determined. Combustion instability and Vortex-Induced
Acoustic Vibrations are studied.
In some furnaces, using simulation of flow and combustion, deflectors were designed to divert the hot
gases prevent failures of furnace walls.
9. General Purpose Lifing Code –
Whenever a large software application involving major multi physics applications, they are conveniently
divided into several modules and integrated on a common platform. Using this approach, TurboManager
is developed to determine the life of turbomachine blades. Various modules developed are:
1. Hysteresis Damping Module [HDM]: Here a stand-alone code for determining Equivalent Viscous
Damping of any structure, rotating or stationary, in any given mode of vibration for a given rotating
speed as a function of Strain Amplitude at a given reference point is determined. This will be one input in
lifing of any structure.
29 Dr. J.S. Rao
2. Coulomb Damping Module [CDM]: In this module a code is developed for determining Equivalent
Viscous Damping of any structure, rotating or stationary, in any given mode of vibration for a given
rotating speed as a function of Strain Amplitude at a given reference point under Coulomb friction at
slipping interfaces. This will be another input in lifing of any structure that can be developed using a
platform approach.
3. Fretting Damping Module [FDM]: Under extreme axial tension, the slipping surfaces are at asperity
level with Hertzian contacts playing a role in micro slip conditions. Special methods are developed to
determine this nonlinear damping as a function of strain amplitude as determined in Coulomb damping
case. This damping model is obtained for the first time that helps in estimating cumulative damage.
4. Critical Speed Map [CSM]: The natural frequencies and mode shapes are first determined by taking
into account stress stiffening and spin softening for a rotating structure. Campbell diagram is obtained
and critical speeds in the operating region are identified.
5. Alternating Pressure Module [APM]: Using the geometry of flow path and appropriate CFD code, the
alternating pressures are determined at all the node points of the structure under consideration whose
critical speeds are determined. FFT analysis is made of these pressures to determine the required
frequency components including the phase angles of the pressures at each node point.
6. Damping Envelope Module [DEM]: Different damping mechanisms are compared in the entire strain
range and the maximum of these are retained to obtain the overall damping envelope for the given mode.
7. Steady Stress Module [SSM]: The steady stress field is obtained by treating the alternation pressures
at zero frequency – this is obtained by a forced vibration analysis with very low frequency (0.001 rad/s)
of the structure.
8. Resonant Stress Module [RSM]: This code is developed on a platform to determine the alternating
stress at a given critical speed. The steady stress field from SSM is used in an iteration process to match
with overall damping envelope obtained by calling DEM as a function of strain amplitude; the SSM
value is divided by twice the value of iterated equivalent viscous damping to obtain the resonant stress
amplitude and stress response at the peak stress location.
9. Failure Surface Module [FSM]: If the peak alternating stress is above Endurance limit and below
Yield value three dimensional Fatigue Failure Surface for the material of the structural component
considering the Mean Stress and S-N diagram is generated. Fatigue reduction factor considering surface
finish, size, stress concentration … is determined and the Failure Surface of the structural component is
determined.
10. Gear Stress calculations are performed to determine the bending and contact stresses by finite
element method; these stresses are compared with AGMA values based on single tooth and Lewis
formula with corrections for bending stress and Hertzian theory with correction factors for contact stress.
Then using Fatigue Reduction factor, the life of transmission units in power plants and drive trains is
determined using FSM.
11. Low Cycle Fatigue [LCF] Module: If the mean stress at a stress raiser location goes into plastic
region, the surrounding elastic stress range determined by accounting for damping is converted to local
stress range by using Neuber‟s hypothesis. Using this local stress, local strain is determined by solving a
transcendental equation for Neuber‟s law. Taking the mean stress into account, the failure surface for
strain based life calculation is determined.
12. Cumulative Damage Module [CDM]: The cumulative damage fraction for each crossing of a critical
speed is determined using Palmgren and Miner linear theory or Marco-Starkey nonlinear theory with
either HCF or LCF as the case may be.
30 Dr. J.S. Rao
13. Number of Start-ups for Life [NSF]: By accumulation of number of cycles for each critical speed
crossing, the cumulative damage for one start-up and shut-down condition is calculated and thus the
number of start-ups of the structures (or the engine) is calculated for safe operation without failure. If the
starting and operating conditions for a given mission of operation as in a fighter aircraft, the damage
fraction for each typical mission are calculated.
14. Fracture Mechanics Module [FMM]: Using Stress Intensity Factor (SIF) or Linear Elastic Fracture
Mechanics (LEFM) approach, a stress raiser location (or a notch) is modeled using a semielliptical notch
model to determine (1) Crack Initiation Threshold level of SIF, SIF for finite cycle crack initiation, (2)
Crack Propagation Threshold SIF once a crack is initiated (3) Crack propagation according to Paris law
and (4) Final crack length for ultimate rupture and therefore crack propagation life.
15. AUTOLIFE Another lifing code for automotive components is also developed specifically addressing
the drive train components and structures under resonant stresses from engine harmonics or transient
excitations when the vehicle negotiates speed breakers.
10. Gravitational Waves and Influence on Earth –
Albert Einstein‟s theory of Relativity is completely proved with the detection of Gravitational Waves on
September 15 2015 and announced on February 11th of 2016; with this all predictions made by Einstein
98 years ago are proven.
Gravitational waves offer a better understanding on how Pangaea travelled northwards and broke up from
southern region to the current location of continents. Gravitational waves carry energy and transfer it to
bodies like earth while passing around them. This energy received can slowly add heat over years and
rise temperature. Also the main sources of energy for movement of the continental tectonic plates can be
explained by the gravitational waves.
Gravitational waves can also be the main source in causing earthquakes from the movement of tectonic
plates one over each other particularly in the regions where discontinuities are present in the mountain
ranges. Therefore Gravitational waves can provide a better understanding of Geology. This work was
sent for publication to Elsevier Journal Engineering Geology.
A finite element model of earth is also prepared and the strain energy of the gravitational waves is
converted to heat energy to determine the temperature raise per second is determined. This modeling
technique will be presented in 4th International NAFEMS conference in Bangalore in August 2016.

16. CONTRIBUTIONS AS SCIENCE COUNSELOR
The Indo-US Sub-commission on Science and Technology was established in 1973. Over the years it has
grown into a major bi-national program in the world. Initially the activities began with Agriculture, then
Health Sciences and continued into the areas of Physical and Chemical Sciences, Environment and
Ecology, Energy and other Engineering areas. Science and Technology Initiative were taken by Mrs.
Gandhi and President Reagan in 1983 to consolidate these programs. Vaccine Action Program was
established in 1987. Agency for International Development has established recently two other major
programs, viz., Project for the Advancement of Commercial Technology (PACT) and Project for
Acceleration of Commercial Energy Research (PACER). In developing these programs and continuing
the ongoing programs good working relations and close contacts are established with various US
Agencies such as White House Office of Science & Technology Policy, National Science Foundation,
National Academy of Sciences, Department of Agriculture, Department of Energy, Agency for
International Development, National Institute of Health, Institute of Medicine, National Academy of
Engineering, National Technical Information Services, American Association for the Advancement of
Science etc. To day the total commitment of both US and India is over 200 million $ spanned over nearly
250 projects for a three year period. A new program Ronald Reagan - Rajiv Gandhi Fellowship Exchange
Program has just been announced.
In the area of Biotechnology, a Standing Advisory Committee consisting of Non Resident Indian
Scientists was established to help the Biotechnology activities in India. Biotechnology Associate-ships
have been introduced for special training at the US Universities and Laboratories. Workshops have been
coordinated in India in this field. An Industry workshop under the PACT program has been conducted in
US with Indian and US industries participating to develop joint ventures. Participating in the Panel of
Scientific Advisers of the International Center of Genetic Engineering and Biotechnology, played a key
role in the identification and selection of Director of the Center and Head of the Delhi Component and
also in identifying areas of work to be concentrated at both the Trieste and Delhi components.
54 Dr. J.S. Rao
Played a key role in the arrangements for the visits of the Prime Minister and Ministers of State for
Science and Technology e.g., in arranging four different meetings with US Scientists to meet the PM in
1985. Arising out of these meetings with Non Resident Scientists, Joint Scientific Groups of Indian
Scientists in US and India were established in Microelectronics and Aeronautics. Such groups in
Biotechnology, Computers and Materials are being established. These groups are playing a Key role in
India, e.g., in Microelectronics, they are helping in identifying short and long term projects and goals in
the process of electronification of India. Arising out of the activities with Indian Scientists in USA, a
large number of export oriented US industries are set up in India, e.g., Texas Instruments, Commodore
Computers, Data General, Indus Technologies etc. A data base of important Indian Scientists has been
established.
Another significant activity has been in the area of Energy, both conventional & non-conventional areas.
Information on clean coal technologies and efficient combustion procedures with fluidized and
circulating beds and combined cycle power generation using coal gasification, magneto hydrodynamics
etc. has been collected through various visits to develop programs with India. Projects on Power plant
Rotating machinery dynamics are being developed with six different US universities and Indian
Institutions. In the area of non-conventional energy, collaborative ventures between Luz International and
Punjab Agro Industries have been developed for Solar Thermal Power Systems. Collaborative programs
in Amorphous Silicon, Ocean Thermal Energy Conversion and other areas are under development.
A very highly successful Science Exhibition has been organized in US. The exhibit was opened in 1985
in Chicago and it toured to Los Angeles, Portland, Seattle, Charlotte and Boston. A significant portion of
this exhibit is retained in US with the American Association of Science Centers for touring at various
places for another two years. This exhibit has projected a very visible and vibrant image of Science in
India to the US public in general. It continues to be very popular. Several conferences and Seminars were
organized to highlight the recent progresses in various aspects of Science & Technology and the resultant
impact on the improvement of quality of life in India. The interaction between the US and Indian
museum scientific personnel has helped a lot in the Science museum activity in India and also in the
development of new programs of Popularization of Science. Several new projects are developed or under
development in various fields. In Agriculture, the thrust is on Biological Nitrogen Fixation, a new
workshop is being organized to enlarge the present programs under the Science and Technology
Initiative. In health area, the major development is in the vaccine field using recombinant DNA.
Continuing Medical Education programs are established between the American Association of
Physicians of Indian Origin and Medical Council of India. Through the generous help of University of
California, Berkeley, Elite School of Optometry was set up at the Madras Research Foundation and
medical equipment continues to be donated by such groups to Indian Hospitals for carrying out advanced
research and health care. Several Institutional Collaborations are being established, e.g., University of
Pittsburgh and Osmania University, University of Illinois and ICMR, Universities of Wisconsin State and
Pushkar Valley Project on Environment etc. Programs of interaction of Indian Scientists of Association
of Scientists of Indian Origin in America are being developed with several Indian Universities for
exchange visits. Cooperation is also extended to the Council of Scientific and Industrial Research in
identifying personnel for the Transfer of Knowledge through Expatriate Nationals Program under UN, to
visit India. Another major activity has been to help Indian Scientists and Students who wish to return to
India in finding the Pool positions of CSIR and appropriate jobs.
