Professor Pavel L. Kirillov has died on October 8th, 2021, on his 95th year after a life as a husband, father, and an internationally renowned scientist, researcher, and educator in the field of nuclear engineering, thermalhydraulics, heat transfer, and two-phase flow. He was a passionate and dedicated in everything, what he has done and leaves an incredible legacy to the profession. He was born on August 20th, 1927 in Russia, and received his M.A.Sc. degree in thermal physics in 1950 (Moscow Power-Engineering Institute (MPEI) (МосковскийЭнергетическйИнститут (МЭИ)), Faculty of Physics and Power Engineering (Физико-ЭнергетическийФакультет), Ph.D. and Doctor of Technical Sciences degrees in 1959 and 1969, respectively. Professor Pavel Leonidovich Kirillov was a respected technical leader, mentor, and friend to innumerable students, researchers, scientists, and engineers, and he will be sadly missed by all, who had the privilege to know him. He was an outstanding contributor in every aspect of his prolific work and career in the true traditions of technical excellence and critical thinking, and his irreplaceable loss is deeply felt worldwide.

Preface

School-Seminar of Young Scientists and Specialists (SSYSS) under the leadership of the academician of RAS A.I. Leontiev “Problems of Heat and Mass Transfer and Gas Dynamics in Power Plants” is organized by National Committee for Heat and Mass Transfer, Russian Academy of Sciences. It has been held every two years since 1977. The School-Seminar brings together young researchers and leading scientists working in the field of heat and mass transfer, and provides an opportunity for open discussion and assessment of the results obtained. In 2021, the Institute of Thermal Physics of the Ural Branch of RAS was the co-organizer of the School-Seminar, therefore XXIII SSYSS was held for the first time in the Urals near Ekaterinburg on May 24th - 28th 2021. More than 150 reports were included in the scientific program, including about 30 lectures of leading Russian thermophysicists. Due to the current situation of COVID-19 epidemic, some lectures took place online. List of Committee are available in this pdf.

Becoming Large, Becoming Infinite: The Anatomy of Thermal Physics and Phase Transitions in Finite Systems

This paper presents an in-depth analysis of the anatomy of both thermodynamics and statistical mechanics, together with the relationships between their constituent parts. Based on this analysis, using the renormalization group and finite-size scaling, we give a definition of a large but finite system and argue that phase transitions are represented correctly, as incipient singularities in such systems. We describe the role of the thermodynamic limit. And we explore the implications of this picture of critical phenomena for the questions of reduction and emergence.

Determination of Object Temperature Influenced by Ambient Temperature as a Solution of Newton’s Law of Cooling or Heating Rates

Thermal physics experiments often require accurate data about the thermal condition of the observed object so that its temperature should be measured. The object temperature, which is observed directly using a measuring instrument, does not represent its actual thermal condition because there is an influence of the object temperature and the ambient temperature differences, especially if the object is not in adiabatic isolation. Newton’s Law on cooling or heating rate is used to determine the actual object temperature if the ambient influence is eliminated. The method used in this research is matching analyses between mathematical solutions and empirical data. In thermal physics experiments in laboratories, particularly in the Basic Physics Laboratory, the influence of ambient temperature-known as Newton Correction-often uses a linear temperature-change approach to time. Thus, an analysis of the differential equation model of Newton’s Law of cooling and heating rates is carried out. The result shows that the objects temperature function over time is in the form of an exponential function, both for a constant ambient temperature, and an ambient temperature that changes over time. The result of this analysis is also in line with the experimental data of the Mechanical Heat Equivalence experiment conducted in the Basic Physics Laboratory of Bandung State Polytechnic.

Thermal Physics and Glaucoma II: Preliminary Evidences for a Thermophysical Design of a Possible Visible-Light-Photons Therapy

Recently, a non-equilibrium thermodynamic approach has been developed in order to model the fundamental role of the membrane electric potential in the cell behaviour. A related new viewpoint is introduced, with a design of a photobiomodulation treatment in order to restore part of the visual field. Here, a first step in experimental evidence of the validity of the thermodynamic approach is developed. This result represents the starting point for future experimental improvements for light stimulation in order to improve the quality of life of the patients. The future possible therapy will be in addition to the pharmacological treatments.

Discrete systems in thermal physics and engineering: a glance from non-equilibrium thermodynamics

Non-equilibrium processes in Schottky systems generate by projection onto the equilibrium subspace reversible accompanying processes for which the non-equilibrium variables are functions of the equilibrium ones. The embedding theorem which guarantees the compatibility of the accompanying processes with the non-equilibrium entropy is proved. The non-equilibrium entropy is defined as a state function on the non-equilibrium state space containing the contact temperature as a non-equilibrium variable. If the entropy production does not depend on the internal energy, the contact temperature changes into the thermostatic temperature also in non-equilibrium, a fact which allows to use temperature as a primitive concept in non-equilibrium. The dissipation inequality is revisited, and an efficiency of generalized cyclic processes beyond the Carnot process is achieved.

In detail explanation for the “Proof of the Twin Prime Conjecture” and its applications to thermal physics

Twin prime numbers are two prime numbers which have the difference equals to exactly 2. In other words, twin primes is a pair of two prime numbers which have the value of the difference exactly two. Sometimes the word “twin prime” is used for a pair of twin primes; an another name for this is considered as “prime twin” or called as “prime pajir”. Up to date there is no any exact proof/disproof for twin prime conjecture since roughly 200 years in the world. Through this research paper, my attempt is to provide a valid proof for twin prime conjecture. This new paper is the detailed explanation of my previous paper that I completed on mid of the year 2020 titled as ‘Proof of Twin Prime Conjecture that can be obtained by using Contradiction method in Mathematics’ (WHICH IS WELL-RECONGNIZED ALL OVER THE WORLD through researchgate as well). And this proof of the existence of infinitely many twin primes can be applied to many subject areas in Physics, Chemistry and etc. And the proof of twin prime conjecture can be used to solve several unsolved problems in Physics, Chemistry and etc as well. Also as an additional result, at the end of this research paper, it discusses about an application of the Proof of Twin Prime Conjecture to the Quantum and Thermal Physics. There, this research paper consider three space volumes symbolized as area A , B and C. Inside areas A and B there are microscopic particles separately. By applying the proof of the twin prime conjecture, finally this will try to conclude that although the areas A and B have separated by area C, there are some particles those have moved from the area B to area A (due to the high thermal pressure of area B).
