ABSTRACT
Centrifugal blowers are used in naval applications and
motors which have high noise levels. The noise
generated by a rotating component is mainly due to
random loading force on the blades and periodic
iteration of incoming air with the blades of the rotor.
The Contemporary blades in naval applications are
made up of Aluminum or Steel and generate noise that
causes disturbance to the people working near the
blower.
The present work aim is to change the no. of blades and
material then performing the different analysis like
static and flow simulation to find the optimum no.of
blades and best material which is increase its efficiency
by using the software SOLID WORKS 2016

1. INTRODUCTION
A centrifugal fan is a mechanical device for
moving air or other gases. The terms "blower" and
"squirrel cage fan" (because it looks like a hamster
wheel) are frequently used as synonyms. These fans
increase the speed of air stream with the rotating
impellers.
They use the kinetic energy of the impellers or the
rotating blade to increase the pressure of the air/gas
stream which in turn moves them against the resistance
caused by ducts, dampers and other components.
Centrifugal fans accelerate air radically, changing the
direction (typically by 90°) of the airflow. They are
sturdy, quiet, reliable, and capable of operating over a
wide range of conditions.
1.1 Principle of operation:
The centrifugal fan uses the centrifugal power supplied
from the rotation of impellers to increase the kinetic
energy of air/gases. When the impellers rotate, the gas
particles near the impellers are thrown-off from the
impellers, then moves into the fan casing. As a result,
the kinetic energy of gas is measured as pressure
because of the system resistance offered by the casing
and duct. The gas is then guided to the exit via outlet
ducts. After the gas is thrown-off, the gas pressure in
the middle region of the impellers decreases. The gas
from the impeller eye rushes in to normalize this cycle
repeats and therefore the gas can be continuously
transferred.
1.2 Velocity triangle:
A diagram called a velocity triangle helps us in
determining the flow geometry at the entry and exit of
a blade.

Page No:1004
A minimum number of data are required to draw a
velocity triangle at a point on blade. Some
component of velocity varies at different point on
the blade due to changes in the direction of flow.
These velocities are related by the triangle law of
vector addition:

pp. - 316-321. To study static and dynamic analysis of
blower is to reduce vibrations & impact. Centrifugal
blowers are used extensively for onboard naval
applications have high noise levels.
3. DIFFERENCE BETWEEN FANS AND
BLOWERS
The property that distinguishes a centrifugal fan from a
blower is the pressure ratio it can achieve. In general, a
blower can produce a higher pressure ratio. As
per American Society of Mechanical
Engineers (ASME) the specific ratio - the ratio of the
discharge pressure over the suction pressure – is used
for defining the fans and blowers.
3. 1 Fan characteristics
Fan characteristics can be represented in form of
fan curve(s). The fan curve is a performance curve
for the particular fan under a specific set of
conditions. The fan curve is a graphical
representation of a number of inter-related
parameters. Typically a curve will be developed for
a given set of conditions usually including: fan
volume, system static pressure, fan speed, and
brake horsepower required to drive the fan under
the stated conditions.
3.2 Industrial blowers or fans :
Industrial fans and blowers are machines whose
primary function is to provide a large flow of air or
gas to various processes of many industries. This is
achieved by rotating a number of blades, connected
to a hub and shaft, and driven by a motor
or turbine.

Volume 7, Issue XI, November/2018

Page No:1005
Fig.: Industrial blower
3.3 Functions on industries :
There are many uses for the continuous flow of air or
gas that industrial fans generate, including combustion,
ventilation, aeration, particulate transport, exhaust,
cooling, air-cleaning, and drying, to name a few. The
industries served include electrical power production,
pollution control, metal manufacturing and processing,
cement production, mining, petrochemical, food
processing, cryogenics, and clean rooms.
3.4 Centrifugal fans:
The centrifugal design uses the centrifugal force
generated by a rotating disk, with blades mounted at
right angles to the disk, to impart movement to the air
or gas and increase its pressure.
Fig.: Centrifugal fan
3.5 Axial fans :
The axial design uses axial forces to achieve the
movement of the air or gas, spinning a central hub with
blades extending radially from its outer diameter. The
fluid is moved parallel to the fan wheel's shaft, or axis
of rotation. The axial fan wheel is often contained
within a short section of cylindrical ductwork, to which
inlet and outlet ducting can be connected.

This section describes the most important energy
efficiency opportunities for fans and choose the right
fan.
Important considerations when selecting a fan are (US
DOE, 1989):
f Noise
Rotational speed
Air stream characteristics
Temperature range
Variations in operating conditions
Space constraints and system layout
ƒ Purchase costs, operating costs (determined by
efficiency and maintenance), and operating life But as a
general rule it is important to know that to effectively
improve the performance of fan systems, designers and
operators must understand how other system
components function as well. The “systems approach”
requires knowing the interaction between fans, the
equipment that supports fan operation, and the
components that are served by fans. The use of a
“systems approach” in the fan selection process will
result in a quieter, more efficient, and more reliable
system.
6.1 Reduce the system resistance :
The system resistance curve and the fan curve were
explained in section. The fan operates at a point where
the system resistance curve and the fan curve intersects.
The system resistance has a major role in determining
the performance and efficiency of a fan. The system
resistance also changes depending on the process.
6.2 Maintain fans regularly :
Regular maintenance of fans is important to maintain
their performance levels. Maintenance activities include
(US DOE, 1989):
ƒ Periodic inspection of all system components
ƒ Bearing lubrication and replacement
ƒ Belt tightening and replacement
ƒ Motor repair or replacement
ƒ Fan cleaning
6.3 Control the fan air flow :
Normally, an installed fan operates at a constant speed.
Fig.: Relative Power Consumption among Flow
Control Options
But some situations may require a speed change,
for example more airflow may be needed from the
fan when a new run of duct is added, or less air
flow may be needed if the fan is oversized.
SOLIDWORKS
Solid Works is mechanical design automation
software that takes advantage of the familiar
Microsoft Windows graphical user interface.
It is an easy-to-learn tool which makes it possible
for mechanical designers to quickly sketch ideas,
experiment with features and dimensions, and
produce models and detailed drawings.
A Solid Works model consists of parts, assemblies,
and drawings.
Typically, we start with a sketch, make a base
element, and after that add more highlights to the
model. (One can likewise start with a insert
surface or strong geometry).
We are allowed to refine our plan by including,
changing, or reordering highlights.
Associativity between parts, assemblies, and
drawings that progressions made to one view are
consequently made to every other view.
We can create illustrations or congregations
whenever in the design procedure.

Solid works mechanical design robotization
programming is a component based, parametric
strong demonstrating configuration instrument which
preferred standpoint of the simple to learn windows
TM graphical user interface. We can make
completely relate 3-D strong models with or without
while using programmed or client characterized
relations to catch plan purpose.
Outline aim is the means by which the maker of the
part needs it to react to changes and updates. For
instance, you would need the gap at the highest point
of a drink can to remain at the best surface, paying
little respect to the stature or size of the can. Strong
Works enables you to determine that the opening is
an element on the best surface, and will then respect
your plan aim regardless of what the stature you later
provided for the can. Several factors add to how we
catch outline purpose are Automatic relations,
Equations, added relations and dimensioning.
Several ways a part can be builded like
Layer-cake approach: The layer-cake approach
constructs the section one piece at a time, including
each layer, or feature, onto the past one.
Potter’s wheel approach:
The potter's wheel approach manufactures the part as
a solitary rotated feature. As a solitary draw speaking
to the cross area incorporates all the data and
measurements important to influence the part as one
to include.
Manufacturing approach:
In an assembly, the simple to draw relations is mates.
Similarly as outline relations characterize conditions,
for example, tangency, parallelism, and concentricity
as for portray geometry, get together mates
characterize identical relations as for the individual
parts or segments, permitting the simple development
of assemblies. Solid Works likewise incorporates
extra propelled mating highlights, for example,
designed gear and cam supporter mates, which permit
displayed, adapt congregations to precisely recreate
the rotational development of a real apparatus
prepare.
At long last, sketches can be made either from parts
or congregations. Perspectives are naturally produced
from the strong model, and notes, measurements and
resistances would then be able to be effortlessly
added to the illustration as required. The illustration
module incorporates most paper sizes and norms.
A Solid Works display comprises of parts,
assemblies, and drawings.

instinctively while you plan. Solid Works Simulation
comes in two packs: Solid Works Simulation
Professional and Solid Works Simulation Premium to
fulfill your investigation needs. Solid Works
Simulation abbreviates time to showcase by sparing
time and exertion in hunting down the ideal plan.

Benefits of Simulation:
Subsequent to building your model, you have to
ensure that it performs effectively in the field.
Without investigation devices, this assignment must
be replied by performing costly and tedious item
advancement cycles. An item advancement cycle
regularly incorporates the accompanying advances:
1. Building your model.
2. Building a model of the outline.
3. Testing the model in the field.
4. Evaluating the consequences of the field tests.
5. Modifying the outline in light of the field test
comes about.
Basic Concepts of Analysis:
The product utilizes the Finite Element Method
(FEM). FEM is a numerical system for examining
building outlines. FEM is acknowledged as the
standard investigation technique because of its all
inclusive statement and reasonableness for PC
execution. FEM partitions the model into numerous
little bits of straightforward shapes called elements
adequately supplanting a mind boggling issue by
numerous basic issues that should be unraveled all
the while.
CAD model of a
part
Model subdivided into small
pieces (elements)
Elements share regular focuses called nodes. The
way toward isolating the model into little pieces is
called meshing.
The conduct of every component is notable under all
conceivable help and load situations. The limited
component technique utilizes elements with various
shapes.
The reaction anytime in an element is interjected
from the reaction at the element nodes. Every node is
completely depicted by various parameters relying
upon the investigation compose and the element
utilized. For instance, the temperature of a node
completely depicts its reaction in warm examination.
For auxiliary examinations, the reaction of a node is
depicted, when all is said in done, by three
interpretations and three pivots. These are called
degrees of flexibility (DOFs). Examination utilizing
FEM is called Finite Element Analysis (FEA).
A tetrahedral element. Red dots represent nodes.
Edges of an element can be curved or straight.
The software details the conditions administering the
conduct of every element contemplating its
availability to different elements. These conditions

relate the reaction to known material properties,
restraints, and loads.
Analysis Steps:
The steps needed to perform an analysis depend on
the study type. You complete a study by performing
the following steps:
Create an investigation characterizing its
examination write and options.
If required, characterize parameters of your
investigation. A parameter can be a model
measurement, material property, force value, or
any other input.
Define material properties.
Specify restrictions and burdens.
The program naturally makes a mixed work
when diverse geometries (solid, shell, auxiliary
individuals and so on.) exist in the model.
Define part contact and contact sets.
Mesh the model to separate the model into
numerous little pieces called elements. Fatigue
and optimization thinks about utilize the lattices
in referenced examinations.
Run the examination.
View comes about.
Specific capabilities of Solid works Simulation:
1. Static Analysis:
At the point when loads are connected to a body, the
body twists and the impact of burdens is transmitted
all through the body. The outside loads incite inward
loads and responses to render the body into a
condition of balance. Linear Static examination
displacements, strains, stresses, and response forces
under the impact of connected loads.
2. Thermal Stress Analysis:
Changes in temperature can actuate considerable
misshapenness, strains, and stresses. Thermal stress
examination alludes to static analysis that
incorporates the impact of temperature.
Perform thermal stress examination utilizing one of
the accompanying choices:
• Using a uniform ascent or drop in
temperature for the entire model.
• Using a temperature profile coming about
because of a consistent state or thermal
analysis.
• Using a temperature profile from Flow
Simulation.
3. Frequency analysis :
On the off chance that the plan is subjected to
dynamic situations, static examinations can't be
utilized to assess the reaction. Recurrence studies can
enable you to stay away from reverberation and plan
vibration confinement frameworks. They additionally
frame the reason for assessing the reaction of straight
powerful frameworks where the reaction of a
framework to a dynamic domain is thought to be
equivalent to the summation of the commitments of
the modes considered in the investigation.
4. Dynamic analysis :
Dynamic investigation include:
Design auxiliary and mechanical
frameworks to perform without
disappointment dynamic environment.
Modify framework's qualities (i.e.,
geometry, damping systems, material
properties, and so forth.) to lessen vibration
impacts.
5. Buckling analysis :
Used to calculate the clasping loads and decide the
clasping mode shape. Both linear (Eigen esteem) and
nonlinear buckling investigations are conceivable.
6. Non-linear static analysis:
International Journal of Research
Volume 7, Issue XI, November/2018
ISSN NO:2236-6124
Page No:1011
Every single genuine structure carryon non-linearly
somehow at some level of stacking. At times, straight
investigation might be sufficient. In numerous
different cases, the straight arrangement can deliver
incorrect outcomes in light of the fact that the
presumptions whereupon it is based are abused. Non
linearity can be caused by the material conduct,
extensive removals, and contact conditions. We can
utilize a nonlinear report to take care of a direct issue.
The outcomes can be marginally extraordinary
because of various procedures. In the nonlinear static
investigation, dynamic impacts like inertial and
damping powers are not considered.
7. Drop test studies :
Drop test examines assess the impact of the effect of
a section or assembly with an inflexible or adaptable
planar surface. Dropping a protest on the floor is a
commonplace application and henceforth the name.
The program figures effect and gravity stacks
naturally. No different load or limitations are
permitted.
8. Fatigue Analysis :
Weakness is the prime reason for the disappointment
of numerous items, particularly those made of metals.
Cases of disappointment because of weariness
incorporate, pivoting hardware, jolts, plane wings,
customer items, seaward stages, ships, vehicle axles,
bridges, and bones.
9. Pressure vessel Design study :
In a Pressure Vessel Design study, you combine the
results of static studies with the desired factors. Each
static study has a different set of loads that produce
corresponding results. These loads can be dead loads,
live loads (approximated by static loads), thermal
loads, seismic loads, and so on. The Pressure Vessel
Design study combines the results of the static
studies algebraically using a linear combination or
the square root of the sum of the squares (SRSS).

Meshing in solid works flow simulation:
The Solid Works Flow Simulation mesh consists of
cells in the form of rectangular parallelepipeds. The
Flow Simulation mesh can contain basic cells of
three different types: fluid cells, partial cells and solid
cells see figure below. Basic cells can be split during
the process of refinement. During refinement, each
basic cell is split in eight smaller cells with the same
volume.

Fig.: Refinement of rectangular parallelepiped
Calculation control options:
There are a number of ways in which you can control
your calculations, see table 1.3. As shown in the table
the finishing conditions include refinement number,
iterations, calculation time and travels. Travel is
defined as the number of iterations related to the
propagation of a perturbation through the
computational domain.
Table.: List of calculation control options
Inserting boundarv conditions:
Boundary conditions are required for both the inflow
and outflow faces of internal flow regions with the
exception of enclosures subjected to natural
convection. Visualization of boundary conditions can
be shown with anows of different colors indicating
the type and direction of the boundary condition. The
boundary conditions are divided in three different
types: flow openings, pressure openings and walls.
Table.: List of available boundary conditions in Solid
Works Flow Simulation
Choosing goals:
Goals are criteria used to stop the iterative solution
process. The goals are chosen from the physical
parameters of interest to the user of Flow Simulation.
The use of goals minimizes errors in the calculated
parameters and shortens the total solution time for the
solver. There are five different types of goals:
Global goals, point goals, surface goals, volume
goals and equation goals. The global goal is based on
parameter values determined everywhere in the flow
