The origins of the Conference start from 1970 in the Soviet Union, Novosibirsk. It was organized by Kutateladze Institute of Thermophysics SB RAS. The name of the conference was «Actual problems of thermophysics and physical hydrodynamics». The conference has been organized under this name up to 2015. The conference chairs were academicians of RAS V. E. Nakoryakov, S. V. Alekseenko and D. M. Marckovich. Peer reviewed proceedings of the conference have been published in the format of printed books. In 2016 the conference is reorganized in a new format with a shorter name: «Thermophysics and physical hydrodynamics» (TPH2021). The proceedings of the renewal Conference were published in the Journal of physics: conference series. The conference was held jointly with the scientific youth school «Thermophysics and Physical Hydrodynamics: Modern Challenges» (TPHMC2021). The scientific school is a lecture intensive. Invited lecturers – famous scientists and specialists from all over Russia talk about the achievements of their groups, teams, organizations. The subsequent work of young scientists in the sections of TPH2021 provides an opportunity to look at the challenges facing science in detail, ask questions, and get answers that can give an impetus to the development of their own research. The conference takes place in Sevastopol, a beautiful and honor city in Crimea on the bank of the Black Sea. Ministry of Science and Higher Education of the Russian Federation, Siberian Branch of the Russian Academy of Sciences, National Committee on Heat and Mass Transfer RAS, Lavrentyev Institute of Hydrodynamics SB RAS, Novosibirsk State University, Novosibirsk State Technical University, Marine Hydrophysical Institute RAS, and Sevastopol State University are among other conference organizers besides Kutateladze Institute of thermophysics. The present Conference covers the following topics: heat transfer and hydrodynamics in single phase flows, hydrodynamics and heat and mass transfer in multiphase flows, phase transitions, reacting flow dynamics, detonation processes, numerical methods in thermophysics and physical hydrodynamics, techniques of thermophysics and hydrodynamics experiment, thermophysical properties of substances, heat and mass transfer on micro- and nanoscales, electrophysical phenomena in gaseous and liquid media, heat transfer and hydrodynamics in industrial processes and environment protection. There are more than 180 participants. The proceedings contain 137 papers grouped by topic. The scientific committee appreciates the enormous work of the editorial board and reviewers in the preparation of this volume. We would like to express our sincere thanks to all authors for their research contributions, and to organizers of the conference for their valuable spadework, especially to specialists of MKS LLC.

First Time

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.

The flow and heat transfer of non-Newtonian nanofluids has an extensive range of applications in oceanography, the cooling of metallic plates, melt-spinning, the movement of biological fluids, heat exchangers technology, coating and suspensions. In view of these applications, we studied the steady Marangoni driven boundary layer flow, heat and mass transfer characteristics of a nanofluid. A non-Newtonian second-grade liquid model is used to deliberate the effect of activation energy on the chemically reactive non-Newtonian nanofluid. By applying suitable similarity transformations, the system of governing equations is transformed into a set of ordinary differential equations. These reduced equations are tackled numerically using the Runge–Kutta–Fehlberg fourth-fifth order (RKF-45) method. The velocity, concentration, thermal fields and rate of heat transfer are explored for the embedded non-dimensional parameters graphically. Our results revealed that the escalating values of the Marangoni number improve the velocity gradient and reduce the heat transfer. As the values of the porosity parameter increase, the velocity gradient is reduced and the heat transfer is improved. Finally, the Nusselt number is found to decline as the porosity parameter increases.

Abstract The plate-fin heat exchanger has been widely applied in the field of air separation and aerospace due to its high specific surface area of heat transfer. However, the low heat transfer efficiency of its plate bundles has also attracted more attention. It is of great significance to optimize the structure of plate-fin heat exchanger to improve its heat transfer efficiency. The plate bundle was studied by combining numerical simulation with experiment. Firstly, according to the heat and mass transfer theory, the plate bundle calculation model of plate-fin heat exchanger was established, and the accuracy of the UDF (User-Defined Functions) for describing the mass and heat transfer was verified. Then, the influences of fin structure parameters on the heat and mass transfer characteristics of channel were discussed, including the height, spacing, thickness and length of fins. Finally the influence of various factors on the flow field performance under different flow states was integrated to complete the optimal design of the plate bundle.

In the past three decades, fractal geometry and technique have received considerable attention due to its wide applications in sciences and technologies such as in physics, mathematics, geophysics, oil recovery, material science and engineering, flow and heat and mass transfer in porous media etc. The fractal geometry and technique may become particularly powerful when they are applied to deal with random and disordered media such as porous media, nanofluids, nucleate boiling heat transfer. In this paper, a summary of recent advances is presented in the areas of heat and mass transfer in fractal media by fractal geometry technique. The present overview includes a brief summary of the fractal geometry technique applied in the areas of heat and mass transfer; thermal conductivities of porous media and nanofluids; nucleate boiling heat transfer. A few comments are made with respect to the theoretical studies that should be made in the future.

We investigated heat and mass transfer on water based nanofluid due to the combined effects of homogeneous–heterogeneous reactions, an external magnetic field and internal heat generation. The flow is generated by the movement of a linearly stretched surface, and the nanofluid contains nanoparticles of copper and gold. Exact solutions of the transformed model equations were obtained in terms of hypergeometric functions. To gain more insights regarding subtle impact of fluid and material parameters on the heat and mass transfer characteristics, and the fluid properties, the equations were further solved numerically using the matlab bvp4c solver. The similarities and differences in the behavior, including the heat and mass transfer characteristics, of the copper–water and gold–water nanofluids with respect to changes in the flow parameters were investigated. Finally, we obtained the numerical values of the skin friction and heat transfer coefficients.

Falling Liquid Film

Mathematical model of conjugated heat and mass transfer in absorption on the entrance region of the semi-infinite liquid film of lithium bromide water solution is investigated for different values of Froude number. The calculations shown that larger values of Froude number corresponds to a smaller thickness of the falling film. It was demonstrated that for large values of the Froude number the heat transfer from the surface is greater than for smaller values.
