The Annals of Frontier and Exploratory Science

Announcements

Starting from the second half of 2004 I preferred to change the title, the name of the scientific discipline we are engaged with here at this website. We (I did this) named it in ~1992-94, according to many times slogan that came with the main theorem published in 1967 -- the volume averaged properties, features -- the Volume Averaging Theory (VAT), which was natural at that time.

Since that the name was introduced and used in much of publications, I have noticed the more and more pronounced misunderstanding and misjudgments concerning this definition and the field I am working with my collaborators, co-workers and students. Researchers continue to understand under this name the area, the volume of knowledge and advancements gained via the linear physical processes and phenomena being described mathematically primarily for the averaged variables.

Then the connections and physical interdependencies between the two scales are dropped, ignored. This point of view brought forward most of difficulties into the problem's physical meaning and its methods of solution.

It is the profound issue -- that the physics and mathematics of the Upper scale HSP-VA Equations (models) when being taken alone, apart from the another (Lower) scale physics and mathematics are not giving the advantage of the two scale consideration of the physical problem - Up- and Down Scaleportation. But this particular issue is the Main reason why we are involved in the craft.

I remember that at the beginning of 90-th the reviewers brought in by the DOE, also those used by journals were deeply profoundly unknown to the discipline of VAT (not talking about developments) in the form proliferated at that time by studies of S.Whitaker, W.Gray, and few other researchers not saying about the discipline that had been brought from the overseas, and what I was starting publishing with my US co-workers here. And that was all along in spite of more than 20 years of VAT publications history up to that time if talking about only the USA!

Reviewers seriously requested comparisons with "experiment" and "other" results, not knowing that the experimental scaled science and "other" results for heterogeneous media did not exist at that time (and in many situations do not exist up to now), and such, etc.

The misunderstanding and frustration of the reviewers, students, and professionals in physical and other disciplines who might become involved but fear the volume of new, untaught definitions and the volume of new knowledge forced to re-determine the name of the field.

  • I had started from 2003-2004 to coin the new title - the Hierarchical Scaled Physics-VAT (HSP-VAT), that would serve apparently also for some extended time.

    Apart that of the people's misunderstanding of what is suggested and how to deal with the averaged (Upper scale) equations along with the Lower scale conventional homogeneous equations, and vice-versa, the many other issues are at stake.

    Starting from the main question everybody liked to ask -- So what, what does it mean, if we anyway can not solve these terrible equations and dependencies?

    Great, the question was to the point at that time. But now we have many solutions, even the exact analytical solutions.

    I had agreed well with this question just at the start many years ago, that is why the many issues of what to do and how to understand and interpret the upper scale phenomena and equations gave the birth to the another field than the one traditionally understood under notations used when reading the studies by S.Whitaker, J.Slattery, and W.Gray with their co-authors. While the basic ideas of development of higher scale averaged variables equations are the same, the most of other issues have been determined and treated differently.

    One of the first reasons for going at least two-scale at that time was the nature of the fields of large Lower scale physics - as the turbulence, meteorology, urban air pollution modeling, heat and momentum transport in Heat transfer devices as the heat exchangers, where one can not abandon or ignore or have unsolved the Lower scale Momentum, Mass, and Heat transport problem.

    Well, most of traditional one scale science and engineering do the heat exchangers, for example, models and courses up to this time without the Lower scale physics and math. That is no sense to write down it because communications between both scales physics in Conventional Orthodox Homogeneous Physics (COHP) of XVIII - XX are occurring via adjustable coefficients that have being sought via Homogeneous experiments. No correct theories for this in COHP. The way of thinking is just jump to the Upper scale and try to figure out the "effective" coefficients with using the wrong Homogeneous models for that scale physics.

    Meanwhile, when we want and need to take the lower (and both) scale physics and math correctly, the Upper scale models, equations, solutions and/or characteristics can be sought rigorously and correctly as well.

    Firstly it was done by me in the USSR in ~1982- 1984, see some information on that in Turbulent Transport Two Scale VAT Governing Equations for Obstructed and Porous Media. Introduction

    Meanwhile, it is an appropriate place in this sub-section for telling some of the history of HSP-VAT application to the HEs theory and not only, modeling, and simulation. The matter is and about the authorship and Intellectual Properties (IP) that had been gained outside of some employment (UCLA) and the US.

  • Announcement #2:

    2011. Some Facts from the History of HSP-VAT Founding 1981-2011

    As the response to the keynote talk by I.Catton in 2010 - "Conjugate Heat Transfer Within a Heterogeneous Hierarchical Structure" title of his keynote lecture at (IHTC-14) International Heat Transfer Conference, August 8 - 13, 2010, Washington D.C., USA, (http://www.asmeconferences.org/IHTC14/Keynotes.cfm) we need to say some otherwise statements.

    In his talk there are wordings - "In 1985, he began his work on Volume Averaging Theory (VAT) as a basis for dealing with transport in heterogeneous hierarchical media. This work culminated in a lengthy paper in Advances in Heat Transfer in 2001. This work has continued and now forms the basis for optimization of heat sinks and heat exchangers."

    First of all - Prof. I.Catton could not start the VAT in 1985, as long as I came to the US in 1990, and that was me who named this discipline approximately in 1992-1994 as the VAT (Volume Averaging Theory). Sorry, but I need to disclose this, and this is not in a single case when people liked to get attention via using my IP and publications.

    Before that nobody, neither professors S.Whitaker, J.C.Slattery, W.Gray, nor I.Catton ever used the mathematics, physical concepts for heterogeneous (two scale at least) description of physical problems as the scaled ones, two scale at least, for heterogeneous media, for nonlinear fields, for turbulence, biology, medicine, other sciences, etc., etc.

    Not talking on the coining of the field as the VAT (HSP-VAT now).

    I.Catton used to deal with the heat exchangers (HE) modeling for many years (and for Nuclear Power industry as well) before me, but never came to the ideas of connecting HE theory, modeling and design to the HSP-VAT, or VAT in the 90s.

    Heat Exchangers are the two or more scale thermal and fluid mechanics physics devices.

    That was me, who brought all of that on HEs and other fields to the MAE department of UCLA in 1991 and later on performed the theories, mathematical modeling and simulation specifically for HEs in 1998-2002. Using students and collaborators from many countries actually.

    See on this in all my - "Fundamentals ......"

    especially in "Fundamentals of Hierarchical Scaled Physics (HSP-VAT) Description of Transport and Phenomena in Heterogeneous and Scaled Media"

    as well as in this "Heat Exchangers, and in a few other sub-sections.

    Regarding the "start" in 1985 - that was the start of porous media research by I.Catton in a completely conventional orthodox way - the one scale homogeneous Darcy-Forchheimer type modeling governing equations, the papers on the topic Catton published with his active grad student J.Georgiadis in those few years before my arrival.

    And only my active participation starting in 1991 (Georgiadis left to those days) turned table to the HSP-VAT agenda. I was writing during all the consecutive 11 years to the DOE and DOD, DARPA, corporate research quarters the proposals in the fields of Ht Fluid Mechanics, Ht Thermal Physics, that were the natural fields for the areas of interest at MAE, as well as for other physical sciences that only I had brought in as the Hierarchical, Heterogeneous (Hr, Ht) fields to the department, as the solid state, composites via HSP-VAT, electrodynamics, magnetism, acoustics, medicine, etc., etc. Have copies of those texts and scripts, if anyone would like to look at.

    I.Catton for nearly three years learned the basics to understand and participate in this new for him science. Before my work at MAE of UCLA, he spoke to Whitaker for a few occasions, and left the field unconvinced of its usefulness.

    He told me himself on that - "too much of math and what is the goal, the purpose?"

    It took, as I said, nearly 3 years before I.Catton had acquired the basics of VAT (HSP-VAT) and began believing in that science (HSP-VAT), and consecutively our program manager of that time at DOE (O.Manly).

    And especially, this is my guess, as he witnessed through the years the first of this kind the 2 scale exact solutions in Ht Fluid Mechanics and Thermal Physics which I had developed.

    Some even with collaborators from other countries - as Dr. V.Kushch, Dr. Y.Gordienko, Prof. E.Sergievsky, and other personalities, paying to them myself, not via or by UCLA in the 90s.

    I.Catton knows about that.

    Some of these developments are in the websites, this one - web-1:

  • http://travkin-hspt.com

    and in Russian - web-3: "http://www.travkin-hspt.narod.ru"

    And finally for this short history remark, that was me, who wrote the full text of chapter in the book - Travkin, V.S. and Catton, I. Transport phenomena in heterogeneous media based on volume averaging theory// Advances in Heat Transfer, New York, Academic Press, Vol. 34, pp.1-144, (2001). I.Catton was the minor contributor, co-author. He even rejected acceptance of the compensation from the Avademic Press publishing house, because he knew who was the author. We were in good relationship at that time 98-2000, so he gave me his half-part payment. And I'd acknowledged this.

    At present times, it would be more modest of I.Catton and fair to write that he "had participated and supported the science of HSP-VAT," but not "started" or "invented," and that he was co-authoring the texts along the major contributor.

    Establishment usually attributes all the benefits to themselves in similar situations. Well, with my state of affairs - I am too big fish for that kind of tricks with authorship. Nevertheless, we know the situation in general in the US universities, when the position determines the "major" contributor. This rule is not always truthful, specifically when the lower compensation person having done so many things in the field, that others can not compete.

    It is true also, that I.Catton was following my advices in directions from the 90s - 2002, in the HSP-VAT Optimization of HEs, etc. We have many papers written by me. Yes, there are some grad students, other collaborators, but the theory, texts, ideology, mathematics, physical models all were developed by myself with their and I.Catton participations.

    Many fields, along with solved problems in HSP-VAT have been done by me and my collaborators in the 80s, before arriving to the US and continue developing HSP-VAT (in physics and math) and its applications far beyond the mechanical engineering at MAE of UCLA as, for example, in meteorology, spinning, atomic, particle, and nuclear physics, biophysics, biology, medicine, for many technologies, etc. Along the area of Heat Exchangers scaled transport as well.

    It is interesting - What S.Whitaker, a real one of pioneers since 60s, thinks now on that? In the 90s he told me - that nobody in his department of Chemical Engineering at UC, Davis even understood what he was suggesting and studying. And this is about the really good application field for HSP-VAT such as the chemical reactors modeling and design?

    Now, as I wrote here in this website also in the place - "Global Financial Opportunities in Multiscale Technologies. Introduction", other sub-sections,

    some people seems, who is somehow familiar with the science of HSP-VAT and publishing close to HSP-VAT, are declaring themselves as the "founders"! And it's a fun to read, but is not true.

    It will be enough just to read and compare the bibliography of mine and other major players in local-non-local physics since the 1980s, including internet publications of exclusive texts, materials, web appearances, papers written in Russian as well. The few papers of 80s and 90s after being laid down side by side will tell to specialist and to a student who is the founder of HSP-VAT (VAT). And who suggested to apply, had developed the theories, models and simulated in the HS physics, its applications modeling and design.

    This is the 3-rd stage of recognition according to great names of XIX-XX centuries, when specialists around are in a hurry to join the bandwagon. And it is Great. Something interesting is coming out unending and more essential.

    Prof. A.Nakayama is also suggesting his name as of the person who developed the VAT. Well, we can state that he participated in 90s, is participating now in the one scale half-homogeneous modeling in porous media, started to work in medicine, but had never even written the properly SCALED mathematical statements.

    I would upload to the sub-section - "How not to Scale-Down...or -Up.. ..Analysis of Current Studies on Scaled, Collective Phenomena in Biology Fields Presented as the One-Scale Concepts," the analysis of A.Nakayama and his co-authors VAT statements.

    Right now in these notes here written for the first time the state of the history on the subject of HSP-VAT (VAT).

    We continue these historical notes with the priorities remark on the larger scope things - that among other new directions in HSP-VAT, biology and medicine can be mentioned the following ones that were developed by me. With some ideological, technical and still principal support by Prof. I.Catton, other collaborators. With the help of my associates from a few countries:

    1) - the presentation of the HSP-VAT physics and mathematical models as the Two Scale (at least) directly cross-linked Scaleported physical problems;

    2) - the True Scaled HSP-VAT models physical Closure;

    3) - the HSP-VAT Direct Two-Scale Analytical (mathematical) and Numerical Cross-Linked Modeling and Solutions - Scaleportation;

    4) - the HSP-VAT Heterogeneous Experiments fundamentals, basic concepts, definitions, and techniques for a few fields in Fluid mechanics and Thermal Physics;

    5) - the HSP-VAT Heterogeneous Optimization basics;

    6) - the Non-linear, and Turbulent HSP-VAT physics, models, and simulations have been described, advanced, and took substantial part in the texts;

    7) - the fundamentals of Scaleportation between the atomic scale Electromagnetism and Mesoscale Continuum mechanics Electrodynamics.

    All issues mentioned above have been advanced for the first time for many physical disciplines -- as those presented in this website -- Acoustics, Electrodynamics, Nanoscale and Atomic scale physics, Biotech and Health science applications, Ferromagnetism, Meteorology and Air Pollution modeling, Optics, Semiconductors, Superconductivity, and few Technologies, etc.

    Well, and I am not sorry for this long list, with regard of other researchers claims. This should be announced, this is like agreements in business - if not stated, recorded, then workers and adversaries around do that for themselves.

    The exact Two scale first time obtained by me solutions of common textbooks known problems that cannot be sold in Homogeneous One-Scale statements, but being presented to students as the solutions, can be seen in -

  • "When the 2x2 is not going to be 4 - What to do?"

  • "Classical Problems in Fluid Mechanics"

  • "Classical Problems in Thermal Physics"

  • "Globular Morphology Two Scale Electrostatic Exact Solutions"

  • "Two Scale EM Wave Propagation in Superlattices - 1D Photonic Crystals"

  • "Two Scale Solution for Acoustic Wave Propagation Through the Multilayer Two-Phase Medium,"

  • "Effective Coefficients in Electrodynamics."

    These exact solutions have been demonstrating the potential for treatment of this new type of physics tasks - the two and more scales interconnected strictly problems, and at the same time the reality of interconnection (Scaleportation) of the physical fields acting over the two (at least) scales.

    It is important to note for a public who is not proficient enough in mathematics, that in mathematics the things that just once had been proven are valid and continue to be official, "legally binding" for all similar problems. That means the volume of research, studies that has been gained throughout >40 years in physics of Continuum Heterogeneous media is official, valid, and "legally binding" in all other areas of physics and technologies. Including and sub-atomic fields in physics.

    This said, it is not precluding the great need in HSP research in the sub-atomic physics.

    *****************************************************************************

  • The Clause of Multiscaling ?

  • Announcement #4: The more texts and papers appeared in the last years and more I read them - it is become the pure knowledge - that unfortunately the Concept of - Multiscale, Multiscaling is understood by most of the workers literally, as everyone prefers to understand it ?

    Of course, it became the fashionable topic to use while approaching for funding, that is why so many people suddenly became "multiscaled."

    Mathematicians and most of mechanical engineering professionals as well as physicists want to understand the Multiscale approach, the theory as a method of - the calculation procedure, a numerical method, which allows to get rid of multiphase, multibody challenge difficulties when solving the heterogeneous media ONE SCALE problem ? Like the famous Homogenization theory, which is not really the Multiscale theory.

    It is strange for someone familiar with the literature on homogenization, but true - read down here the subsection in this section - Comparing with Governing Equations and "Averaging" in Homogenization Theory

    which suggests our selective analysis on few main points and issues on derivation of governing equations and their meaning in Homogenization Theory.

    Of course, technically speaking it might be named the multiscale method when few scales those differentiated one from another just by some coefficient (not by physics) being applied to the same mathematical problem governing equations and to the same physical scale model for each of these scales ? But what is really should be understood under the specific different scale models name in this case - is that it is the MULTIRESOLUTION method.

    Meaning, that the same understanding of physical problem and statement is being treated using the different (various) scales for better reflection of the specifics of physics and for easier and better solution of this ONE SCALE HOMOGENEOUS statement problem.

    That's it. Nothing more if not HSP-VAT used. Especially, when the task is set about a heterogeneous medium (material).

    More than ever, when the problem constituted for a heterogeneous medium or when the scales are different by their peculiar physics - as, for example, the scale of a singular star, planet (or an atom) and the scale of a star nebula (or a piece of solid (or other) state medium). Everybody realizes that the difference is of many orders of magnitude. And the physics on each scale is different. Nevertheless, everything and the physics including are interdependent!

    How many physical theories do you know that capable to describe a variety of interdependent via a scale physics phenomena? We are not talking here on one scale traditional physics constructions, of coarse.

    So, the next Announcement I would like to do is about the MULTISCALE definition.

  • The Multiscale, Multiscaling - it is not about the method of calculation of heterogeneous (or multibody) problem !!!! The method of number of scales applied for the solution of the problem is known in mathematics for long time. The Multiscale Problem it is about the Formulation of Different Physical Scales (at least two) Problem and their (different scale problems) Cross-Connection and Solution - that calls a Scaleportation! Not an "ad hoc" or heuristic coupling, but a real relationship which has a mathematical and physical explanation, formulation.

    Some of the inspired by particle physics and biology notes on Scaleportation are given in -

  • - "Reductionism and/versus Holism in Physics and Biology - are Both Defective Concepts without Scaleportation"

    *****************************************************************************

  • Analysis of Published Studies on Heterogeneous and Hierarchical Media

  • Announcement #5: There is our intension in this website first of all to serve better to this field and to people studying and working in it. The issue of analysis of published in the field research papers, reviews, books is the inseparable activity. That is why everybody should accept, understand and think about critical materials appearing on these pages - as of usual component of healthy movement in the area.

    There is no personal critique on these pages. If few names appearing more often than the others - that is because those researchers as, for example, S.Torquato or A.Prosperetti studies are outstanding, and they might be of substantial interest for HSP-VAT, if those persons would do the substantial rethinking in terms of the efforts and return on those efforts, and on the prospective outcome. How much of effort and money spent uselessly in the area of Heterogeneous physics (and Engineering) theory, modeling and experiment is unbelievable when compounding the work for government programs, grants, and contracts done in the lab after lab etc., etc. Not only in the universities and government labs, industries are spending even more.

    Especially at nowadays, when the Nanotechnology and Multiscaling became the magic words.

    Some areas, even when they deserve the attention are out of our time and interests as, for example - the boiling in Thermal Physics. In spite that the theory begins with more or less tedious description of the one bubble produced, not to mention the sufficient morphological features of the surface of boiling. Then, the field is doing well just collecting the experimental data and building heuristic correlations. Because the workers in the field don't know how to combine the multiple bubbles growth in the dense environment. That is the current state of affairs.

    Many other disciplines and sub-disciplines are in the same mode, unfortunately.

    *****************************************************************************

  • Challenging, Unorthodox, Pioneering, Future Physics Spring-Ups.

    It was noticed recently that the "dissident" or better to say "renewing", challenging, unorthodox, pioneering, future physics theories continue sprouting in many areas of physics from the 70s of the last century. Some of them are really vocal and straightly attacking the orthodox "theological" theories of physics mainly, some are rather coward and/or shy.

    We are concerning to a variety of them, just because they (according to their authors) try to remodel or renovate based on the one scale concept(s) assumptions, something that is still a Homogeneous theory in orthodox homogeneous physics. As the new concepts claim the intent to improve, often replace the old obsolete orthodox theories. They do this out of the best their objective; nevertheless, it's all made with the one scale Homogeneous description, even when author(s) address the obvious hierarchical, scaled issues.

    That is why we need to state -

  • Announcement #6: that either all the new pioneering theories in physics need to be sustained in case of heterogeneous, scaled phenomena occurring by the scale re-gauging in connection to their more than a one scale physical concepts, models, and equations or they are doomed to fade, or to be covered as long as they bare the same incorrectness of the homogeneous methodology in this regard as the orthodox homogeneous scaleless physics.

    It is again about the One Scale for All (OSFA) governing equations for the phenomena at the atomic, sub-atomic, continuous, particle physics, heterogeneous, planetary, intergalactic, whatever like for a "Big Bang", etc. scale. That means, so far, people are using the same basic governing equations for any atomic, sub-nuclear and for general relativity (gravitation) models to name a few!

    And this is also the obsolete and incorrect Homogeneous concept in physics.
