The Rybinsk State Aviation Technical University named after P. A. Solovyov hosted the All-Russian scientific conference — the XXV school-seminar of academician A. I. Leontyev “Problems of gas dynamics and heat and mass transfer in power plants”. Students, postgraduates, young scientists and specialists in the field of hydrogas dynamics and thermal physics participated in it.
The founder and director of the school until 2021 is Academician of the Russian Academy of Sciences Alexander Ivanovich Leontiev, a world-famous scientist, laureate of the international Global Energy Prize, who headed the National Committee of the Russian Academy of Sciences on Heat and Mass Transfer, and Honorary Doctor of St. Petersburg Polytechnic University.
Plenary reports were presented by leading Russian thermal physicists, colleagues and students of A. I. Leontiev, including Corresponding Members of the Russian Academy of Sciences N. A. Pribaturin, P. A. Strizhak, L. S. Yanovsky, professors L. A. Dombrovsky, S. A. Isaev, V. I. Terekhov and others.
Associate Professor of the Higher School of Applied Mathematics and Computational Physics of the Physics and Mechanical Institute Sergei Galaev gave a plenary report on “Flow and heat transfer in finned channels designed for cooling turbine blades.”
Young researchers from SPbPU took an active part in the meetings. Associate Professor of the Higher School of Nuclear and Thermal Engineering Elizaveta Kolesnik presented a report on “Modeling of Film Condensation Processes on a Vertical Plate by the VOF Method”. Assistant of the Higher School of Nuclear and Thermal Energy of the Institute of Power Engineering Pavel Bobylev spoke about the intensification of heat exchange during boiling on a finned surface.
Traditionally, the event included a discussion of sectional poster presentations with the selection of the best in each section. The distinguished authors were awarded diplomas and prizes.
Assistant of the Higher School of Applied Mathematics and Wind Engineering Anna Podmarkova presented a report “Analysis of the Efficiency of Ventilation with Multi-Jet Supply of Incoming Air”. Postgraduate student Vladislav Adiatullin devoted his presentation to self-oscillating modes of the flow of counter-wall jets in a rectangular cavity. Student of the Applied Mathematics and Physics program Tatyana Korskova presented a report “Numerical Study of Air Mixing in a Ventilated Space with Supply of an Incoming Jet Through an Oscillator”. Student of the Applied Mathematics and Physics program Daniil Ageyev presented a study of free air convection near a single horizontal finned tube.
Following the results of the school-seminar, four Polytechnic students were among the section winners. Assistant of the Higher School of Applied Mathematics and Wind Engineering Elena Babich shared her research on the flow structure and local heat transfer during supersonic flow past a cylinder limited at the ends by parallel plates. Student of the Higher School of Applied Mathematics and Technical Electrification Sergey Knyazev spoke about a comprehensive study of heat transfer during flow past a cylinder with turbulators. Student of the Applied Mathematics and Physics program Denis Kuchiev presented a report on “Numerical modeling of turbulent free convection in a layer with volumetric heat release using LES and RANS approaches”. PhD student of the PhysMechanics Department Daria Popova devoted her presentation to modeling non-stationary processes in a cooled stage of a turbine based on the harmonic balance method.
The conference provided a deep analysis of the current problems of the industry, including modeling of flows, heat exchange in complex systems and advanced materials. Koprino Bay on the Volga bank contributed to concentrated work. The calm atmosphere, remoteness from the bustle of the city and the availability of the necessary infrastructure created comfortable conditions for scientific work. I was pleasantly surprised that my work received a positive assessment from experts. Recognition of the relevance and significance of the study by colleagues is an important incentive for further work, – shared Denis Kuchiev.
