Some Challenges in Thermoscience: More details in my following lectures/discussions
www.kostic.niu.edu
• Nature of Thermo-Mechanical energy transfer (Electro-magnetic …Photons, Phonons, Thermons)
• Thermal energy concept as property (decoupling from thermo-mechanical internal energy): Caloric, Exergy, Entransy
• Back to Caloric (Thermal Energy), caloric processes (conserved caloric regardless of irreversibility if complete)…Heat is Unique (all else is Work) and Universal (all works ultimately dissipate/convert to heat)
• Reversible adding work or heat results in different final states (different types of internal energies). However, reversible work between two states path is independent!
• Entropy is dimensionless ratio (!) since temperature is a micro-particle kinetic energy!• Isentropic processes conserve entropy, thus when a work is extracted the remaining
thermal energy at lower temperature is at constant (conserved) entropy.• Produced entropy cannot be “destroyed” by any means, it could only be transferred
with thermal energy, thus entropy production is irreversible! • Entropy is increasing with irreversible conversion of any work-potential (including
thermal work potential) the latter due to non-equilibrium, thus terminal and maximum at equilibrium.
• Carnot principle defines the both: work potential and reversible heat transfer• Useful or Available Energy - Exergy is additive state function for a given reference
(dead state of surrounding-ultimate equilibrium: Po, To, MUo), just like other state functions (energy, etc.).
Slide 16
Energy and Environmental Landscape …
… could be substantially enhanced with improved efficiency and diversification of energy sources, devices and processes.
We are now in transitional era where further progress cannot be continued with existing technology. The difficulties that will face every nation and the world in meeting energy needs over the next several decades will be more challenging than what we anticipate now.
www.kostic.niu.edu
Slide 17
Challenges are many …
… but so are potentials for innovative solutions based on further development of science and technology.
As new paradigms are to be developed, the thermoscience (thermodynamics and heat transfer), being “the heart and soul” of all energy sciences, holds the key to provide vision and check-and-balance methods for optimizations and further innovations.
www.kostic.niu.edu
Slide 18
From Fundamentals to Innovations
The fundamental Laws of Thermodynamics and comprehensive analysis and optimization are the most effective way for the improvements and could lead to innovative development.
www.kostic.niu.edu
… our objective is to motivate young researchers/students to be excited and
be persistent to reason and value fundamentals in order to innovate
Slide 19
The Fundamental Laws of Nature
• The fundamental Laws of Nature are exceptionally simple but they appear in exceptionally many different forms, which explain universality and unity of simplicity and complexity, but also difficulties to recognize simplicity in complex diversity
www.kostic.niu.edu
Slide 20
Cause Is Adequate to the Effect …
• The philosophic axiom
"causa aequat effectum," [the cause is adequate to the effect]
is traced to ancient philosophers and represents the most universal and fundamental law of nature, including existence and future, i.e. past and future transformations.
www.kostic.niu.edu
Slide 21
Phenomenological Laws
• Furthermore, the phenomenological Laws
of Thermodynamics, and in general, have much wider, including philosophical significance and implication, than their simple expressions based on the experimental observations – they are the Fundamental Laws of Nature.
• They are defining and unifying our comprehension of all existence in universe and all changes in time (all processes, including life).
www.kostic.niu.edu
Einstein stated that, “After mathematicians invaded (and
explained) my Theory of Relativity, I do not understand it any more.”
Slide 22
The Fundamental Laws of Nature:
The Laws of Thermodynamics have much wider, including philosophical significance and implication, than their simple expressions based on the experimental observations, they are:
The Fundamental Laws of Nature: • The Zeroth (equilibrium existentialism), • The First (conservational transformationalism), • The Second (forced-directional, irreversible transformationalism),• The Third (unattainability of emptiness).
The Laws are defining and unifying our comprehension of all existence and transformations in the universe.
www.kostic.niu.edu
Solving practical problems helps "really" understand theory, so that one can then solve other problems more effectively. If we can not solve a problem, that "proves" we do not "truly" understand theory -- the key is integration/synergy of theory and practice, the "true" UNDERSTANDING! If one thinks theory is boring, that means one is not really interested in understanding to solve practical problems.
Slide 23www.kostic.niu.edu
Thermal energy versus Internal energy concepts in Thermodynamics:
The T, Cth, Entropy are related to internal thermal energy, not any internal energy (the latter obvious for incompressible substances), but is more subtle for compressible gases due to coupling of internal thermal energy (transferred as heat TdS) and internal elastic-mechanical energy (transferred as work PdV). Entropy is NOT related to any other internal energy type, but thermal (unless the former is converted/dissipated to thermal in a process).
Slide 24
Mechanical and Thermal Energies
Are Distinguishable Within Internal Energy!DU12s= DU12v
U2s=U2v
U=Uth+Umech(elastic)
T2s=T2v (for Ideal Gas)
BUT!2s≠2v
Ps>Pv; Ss<Sv
Vs<Vv, Uth,s<Uth,v & Umech,s>Umech,v
Exs>Exv etc.

1 kJ heating is NOT the SAME as 1 kJ compressing!Thermal and Mechanical energies are distinguishable, NOT the same Internal energy (as argued by some)!
Slide 26
Heat Is Transfer of Thermal Energy
• Philosophically, you cannot transfer something that does not exist.For example, you cannot transfer water unless you have water. You cannot transfer energy (type) without having it somewhere (stored) to transfer and store it somewhere else. In the process (while transferring) you may convert/reprocess (modify the "original structure") while conserving the underlying substructure (true elementary particles): existential conservationism.
• Denying existence of thermal energy is the same as denying existence of heat transfer!

Slide 27
Useful Energy: Work potential, Exergy (and Entransy) concept(s)
Two systems in non-equilibrium have potential of extracting work (useful energy). The maximum work potential is if they are reversibly brought to mutual equilibrium while the work is extracted (entropy is conserved, thus over-all isentropic), otherwise part or in-whole that work potential will dissipate via heat to thermal energy and generate entropy.
If one system is fixed, an infinite thermal reservoir and taken as a reference (like environment at To & Po) then that maximum work potential depends on the other system state, i.e., it is independent of the process path, thus the system property, called Exergy.
Note that there will be a need to reversibly exchange heat (and entropy) at the reference temperature or reversibly regenerate heat internally, except for isentropic processes.

All reversible processes are “over-all isentropic” (entropy conserved)!
Exergy analysis to minimize and optimize irreversibility
Entransy analysis to maximize and optimize heat transfer
Slide 30www.kostic.niu.edu
Slide 31
The Concept of "Entransy" May Be More Important Than What It Appears at First
… but it has to be "properly" related to existing concepts of Thermal energy (not precisely defined yet, see elsewhere), Exergy and Entropy, as well as irreversibility and reversibility.
Entransy concept and analysis have some unique advantages over other approaches. There is a need to define Entransy as a property (how it relates to other thermodynamic properties) and as process energy flux (how it relates to heat & work transfer and entropy transfer & generation). We also could advance and synergize your "Thermomass" concept with my work in that area.

Slide 32www.kostic.niu.edu
What is Energy ?
If one could expel all energy out of a physical system … … then empty, nothing will be left …
… so ENERGY is EVERYTHING … E=mc2
Mass (m) and energy (E) are manifestation of each other and are equivalent;they have a holistic meaning of “mass-energy”
More important than what it appears to be
Slide 33www.kostic.niu.edu
What is Energy ?“From the Sovereign Sun to the deluge of photons out of the astounding compaction and increase of
power-density in computer chips …
Mass-Energy represents motion of a system structure, i.e., its representative particles at different space and time scales, and ultimately motion of photons.

Humanity’s Top Ten Problemsfor next 40 years
1. ENERGY (critical for the rest nine)2. Water3. Food4. Environment 5. Poverty6. Terrorism & War7. Disease8. Education9. Democracy10. Population
2013: Over 7 Billion People
2050: ~ 10 Billion ( 1010 +) People
Slide 35www.kostic.niu.edu
The two things are certaineven if man-made Global Warming is debatable
• (1) the world population and their living-standard expectations will substantially increase(over 7 billion people now, in 50 years 10-11 billion - energy may double)
• (2) fossil fuels’ economical reserves, particularly oil and natural gas, will substantially decrease(oil may run out in 30-50 years)
Efficient and Sustainable EnergyEnergy/Economy/Ecology Challenges and Opportunities
• We are in 'energy transition era' from fossil fuels to alternative (including nuclear) and renewable energy sources (including solar, biomass, hydro, wind, and geothermal).
Efficient and Sustainable EnergyEnergy/Economy/Ecology Challenges and Opportunities
• In this transitional era, the energy CONSERVATION and EFFICIENCY (including energy storage) is the most “effective" and thus the most viable/profitable option in initial and mid-range period, until alternative and renewable energy infrastructure is developed and matured, and even more so beyond.
Efficient and Sustainable EnergyEnergy/Economy/Ecology Challenges and Opportunities

Electromagnetic Natureof Thermo-Mechanical Mass-Energy Transfer
Due to Photon Diffusive Re-Emission and Propagation
Prof. M. KosticMechanical EngineeringNORTHERN ILLINOIS UNIVERSITY
International Forum on Frontier Theories in Thermal ScienceTsinghua University, Beijing, China, December 18-20, 2011
Based on atomic electron-shell interactionsand the Einstein mass-energy equivalence, during “believed-massless” heat conduction
or mechanical work transfer, there has to be electromagnetic, i.e., photon mass-energy propagation
(since they are not gravitational and not nuclear interactions)through involved material structures, from a mass-energy source to a sink system. Otherwise, the mass-energy equivalence and Physics
law of forced interactions will be violated!
Slide 56www.kostic.niu.edu
Fig.1: Electromagnetic Nature of Thermo-Mechanical Mass-Energy Transfer Due to Photon Diffusive Re-Emission and Propagation: Steady-state, mass-energy transfer is depicted through heat conduction plate (right-above) and rotating shaft (right-below). Energy transfer (i.e., Einstein’s mass-energy equivalency transfer, ) has to be electromagnetic by photon transfer, either as photon electromagnetic waves on-long range through space/vacuum (, or photon “on-contact” transfer within material structures, e.g., through heat conduction plate (rt.-above) and turbine shaft work (rt.- below). Otherwise, Einstein’s mass-energy equivalency and the fundamental force/interactions in Physics will be violated.
Slide 57© M. Kostic <www.kostic.niu.edu>
“The Second Law of Thermodynamics is considered one of the central laws of science, engineering and technology. For over a century it has been assumed to be inviolable by the scientific community. Over the last 10-20 years, however, more than two dozen challenges to it have appeared in the physical literature - more than during any other period in its 150-year history.”
Second Law Conference: Status and Challengeswith Prof. Sheehan in Sun Diego, CA June 2011
Slide 58www.kostic.niu.edu
The Second Law Symposium has been a unique gathering of the unorthodox physicist and inventors (to avoid using a stronger word)
Slide 59www.kostic.niu.edu
Fig. 8: Significance of the Carnot’s reasoning of reversible cycles is in many ways comparable with the Einstein’s relativity theory in modern times. The Carnot Ratio Equality is much more important than what it appears at first. It is probably the most important equation in Thermodynamics and among the most important equations in natural sciences.
The “Key Fundamental Concepts” are much more important than what they
appear to be

Slide 61www.kostic.niu.edu
Entropy, the thermal displacement property, dS=dQrev/T (or dQcal/T) with J/K unit,
is “a measure” of thermal dynamic-disorder or thermal randomness, and may be expressed as being related to logarithm of number of “all thermal, dynamic-microstates”, or to their
logarithmic-probability or uncertainty, that
corresponds, or are consistent with the given
thermodynamic macrostate. Note that the
meanings of all relevant adjectives are deeply important to reflect reality and as such it has
metaphoric description for real systems.
Qcal=Qrev+Wloss=Qrev+Qdiss
Slide 62www.kostic.niu.edu
A system form and/or functional order/disorder:
A system form and/or function related order or disorder is not thermal-energy order/disorder, and the former is not the latter, thus not related to Thermodynamic entropy. Entropy is always generated (due to ‘energy dissipation’) during production of form/function order or disorder, including information, i.e., during any process of creating or destroying, i.e., transforming any material structure. Expanding entropy to any type disorder or information is unjustified, misleading and plain wrong.
Slide 63www.kostic.niu.edu
Entropy refers to dynamic thermal-disorder of its micro structure (which give rise to temperature, heat capacity, entropy and thermal energy. It does not refer to form-nor functional-disorder of macro-structure: For example, the same ordered or piled bricks (see above) at the same temperature have the same entropy (the same Thermodynamic state)!
Entropy and Disorder …S=S(T,V) not of other type of disorder:
If Tleft=Tright and Vleft=Vright Sleft=Sright
Slide 64
The Boltzmann constant is a conversion factor:
Temperature is (random kinetic) thermal-energy of a (micro-thermal) particle (with Boltzmann constant being the conversion factor between micro-thermal energy and macro-temperature), … thus entropy is ration between macro (multi-particle) thermal energy and a representative particle thermal-energy, thus dimensionless.
[J/(K )]
The thermal-energy used for entropy is without its ‘useful’ part or work potential, thus include pressure-volume influence. In that regard, a single particle entropy without thermal-interactions is zero (no random-thermal motion), but also infinity (as if in infinite volume, taking forever to thermally interact).

Slide 65www.kostic.niu.edu
Sgen
Entropy Generation (Production) is always irreversible in one direction only, occurring during a process within a system and stored as entropy property. Entropy cannot be destroyed under any circumstances, since it will imply spontaneous heat transfer from lower to higher temperature or imply higher efficiency than the ideal Carnot cycle engine

YES! Miracles are possible !It may look ‘perpetuum mobile’ but miracles are real too …
… we could not comprehend energy conservation until 1850s: (mechanical energy was escaping “without being noticed how”)
… we may not comprehend now new energy conversions and wrongly believe they are not possible: (“cold fusion” seems impossible for now … ?)
…….Let us keep our eyesand our minds ‘open’ ………..
Things and Events are both, MORE but also LESS complex than how they appear and we ‘see’ them -- it is
natural simplicity in real complexity
… but, the miracles are until they are comprehended and understood !

However, regardless of imminent shortages of fossil fuels, the outlook for future energy needs is encouraging. Energy conservation “with existing technology” (insulation, regeneration, cogeneration and optimization with energy storage) has real immediate potential to substantially reduce energy dependence on fossil fuels and enable use of alternative and renewable energy sources. There are many diverse and abundant energy sources with promising future potentials, so that mankind should be able to enhance its activities, standard and quality of living, by diversifying energy sources, and by improving energy conversion and utilization efficiencies, while at the same time increasing safety and reducing environmental pollution. After all, in the wake of a short history of fossil fuels’ abundance and use (a blip on a human history radar screen), the life may be happier after the fossil fuel era!

Stretching the mind further …
Mass may be a special tensor-like quantity due to "over-all-isotropic in all-directions" motion of elementary particles (that make up its structure) and thus give rise to inertia if accelerated in any direction, i.e., resisting change of motion in any and all directions with equal components (the isotropic mass inertia). There may be anisotropic masses, with bulk linear or rotational motion, being the extreme cases. Note that fundamental particles (without inertial mass, like photons and similar, but with relativistic masses E/c^2) has to always move with ultimate speed of light in vacuum, and such particles (some yet to be discovered) might be moving (orbiting with twisting, string-like vibration and rotation) within virtually infinitesimal spaces and thus making-up other "massive" so-called elementary particles

Force and Forcing …
Force or Forcing is a process of exchanging useful-energy (forced displacement) with net-zero exchange at forced equilibrium. The Second Law provides conditions and limits for process forcing (energy exchange direction

Deterministic vs. Probabilistic
All interactions in nature are physical and based on simple cause-and-effect conservation laws, thus deterministic and should be without any exceptional phenomenon. Due to diversity and complexity of large systems, we would never be able to observe deterministic phenomena with full details but have to use holistic and probabilistic approach for observation; therefore, our observation methodology is holistic and probabilistic, but phenomena have to be deterministic, not miraculous nor probabilistic

Elementary Particles: Electron?
There is no proof that an electron, or any other elementary particle, has or does not have a structure. The concept of elementary particle is intrinsically problematic (just because we cannot observe or reason a structure which exhibits certain phenomena, does not mean it does not exist). Past and recent history proved us to be wrong every time. Particularly problematic is the current theory which requires elementary particle annihilation/creation (“miraculous creationism”) while using conservation laws. At the very least (in phenomenological view) the elementary particles should be conserved and be the building structure for other particles and systems. Note that many concepts (in modern physics) are "virtual" entities that are part of the mathematical theory, but are not directly observable.

Slide 101
Boundary Forces …
There is no such thing as a unidirectional force or a force that acts on only one body (no imaginary boundary vector-forces). Put it very simply: a forcing (force-flux cause-and-effect phenomena) acts between an interface of pair of objects (forced interaction: action-reaction, including process-inertial forces), and not on a single object. The Newton Laws and the Laws of Thermodynamics imply that all forces are mass-energy interactions (forced displacements with momentum and energy transfer and conservation) between different particulate bodies due to non-equilibrium (available energy or work potential, cause of forcing) towards the equilibrium.

Slide 102
No Perfect Rigidity …
All matter must be somewhat elastic (can be compressed or stretched). If bodies could be perfectly rigid we'd have infinite forces acting with infinite speeds for infinitesimal times (if you pushed on one end of a perfectly rigid stick, the other end would move instantaneously). System components (bodies) that exert forces have to be massive (2nd Newton Law) and with accompanying reaction forces (3rd Newton Law).

Slide 103
Energy is bound by forced motion …Energy is possessed (thus equilibrium property) by material systems and redistributed (transferred) between and within system(s), due to systems' non-equilibrium, via forced-displacement interactions (process) towards the equilibrium (equi-partition of energy over mass and space); thus energy is conserved (the 1st Law) but degraded (the 2nd Law). Effects are consequences of Causes except at Equilibrium they are equal (reversible). The existence in space and transformations in time are manifestations of perpetual mass-energy forced displacement processes: with net-zero mass-energy transfer in equilibrium (equilibrium process) and non-zero mass-energy transfer in non-equilibrium (active process) towards equilibrium. System components (particles and bodies) that exert forces have to be massive (2nd Newton Law) and with accompanying reaction forces (3rd Newton Law).

Processes … Miracles
"Nothing occurs locally nor in the universe without mass-energy exchange/conversion and irreversible entropy production.
It is crystal-clear (to me) that all confusions related to the far-reaching fundamental Laws of Thermodynamics, and especially the Second Law (Abstract), are due to the lack of their genuine and subtle comprehension."
The miracles are until they are comprehended and understood.

The Concept of "Entransy" May Be More Important Than What It Appears at First
… but it has to be "properly" related to existing concepts of Thermal energy (not precisely defined yet, see elsewhere), Exergy and Entropy, as well as irreversibility and reversibility.
Entransy concept and analysis have some unique advantages over other approaches. There is a need to define Entransy as a property (how it relates to other thermodynamic properties) and as process energy flux (how it relates to heat & work transfer and entropy transfer & generation). We also could advance and synergize your "Thermomass" concept with my work in that area.
