Symposium audience
On October 20 and 21, the National (All-Russian) Symposium "Numerical Modeling in Climate Systems" was held at the Department of Heat, Gas Supply, and Ventilation at SPbGASU. The event brought together scientists, faculty, and specialists from various Russian cities, including St. Petersburg, Kazan, Moscow, Voronezh, Belgorod, Kursk, and Ukhta.
Symposium participants discussed current research in the field of numerical modeling of heating, ventilation, air conditioning, and gas supply systems. Topics covered included the prospects for using numerical modeling in the design of heating, ventilation, and air conditioning systems, the development and verification of a numerical model for radiative-convective heat transfer in a long radiant heater, the use of user-defined flow functions (UDFs) in numerical analysis of tube deposits in convective bundles of water-tube boilers, and a post-processing algorithm for numerical modeling results for quantitatively assessing laminar flow in cleanrooms.
The symposium opened with a presentation by Arslan Ziganshin, Doctor of Engineering and Head of the Department of Information Systems and Technologies in Construction at the Kazan State University of Architecture and Civil Engineering. He presented a study of the flow in a "knee-symmetrical tee" ventilation system and proposed solutions for improving its energy efficiency.
Andrey Kolosnitsyn, CEO of MM-Technologies LLC, addressed the pressing issue of transitioning to domestic software. In his presentation, he analyzed the strengths and weaknesses of Russian programs FlowVision, Logos, and CadFlo, as well as their development prospects for science and practice.
Ural Federal University specialists presented the results of a comparison of gas dynamics and heat transfer calculations for air ducts using ANSYS CFX and SimFlow software to develop an engineering modeling method.
Kristina Kocharyantz, Research Director and Head of the Aerodynamics and Acoustics Research Laboratory at Arktos LLC, addressed a pressing issue for numerical modeling specialists. She discussed the specifics of developing and optimizing air diffuser models for numerical calculations of indoor microclimates. Many undergraduate and graduate students simplify their numerical models in areas such as air inlet areas near ventilation grilles and diffusers, which is often erroneous, as it yields incorrect air distribution calculations. The presentation presented the results of an analysis of various air diffusers with recommended boundary conditions and described options for optimizing numerical models for various cases.
Yegor Aralov, a graduate student at Southwestern State University, addressed the pressing issue of gas infrastructure safety. His presentation focused on digital technologies for monitoring the condition of low-pressure gas pipelines in extremely cold conditions, which significantly improves their reliability.
Faculty and students from Moscow State University of Civil Engineering presented joint work: Associate Professor Elena Belova and student Vyacheslav Vlasenko reviewed mathematical models of air dehumidification, while Associate Professor Sergei Tikhomirov presented the results of a numerical study of the influence of radiator geometry on the laminar-turbulent transition.
Postgraduate and master's students from the Department of Heat and Gas Supply and Ventilation at St. Petersburg State University of Architecture and Civil Engineering (SPbGASU) presented the results of their research.
The scientific program concluded with a presentation by Tamara Datsyuk, Doctor of Engineering, Professor of the Department of Construction Physics, Electric Power Engineering, and Electrical Engineering at St. Petersburg State University of Architecture and Civil Engineering. She summarized twenty years of experience using numerical modeling at our university.
The symposium concluded with a roundtable discussion, where participants had the opportunity to informally discuss the topics raised and identify avenues for further collaboration. The event served as an important platform for exchanging experiences between leading experts, young scientists, and industry representatives.
