the XII All-Russian Conference “Thermophysics and Power Engineering in Academic Centers” (TPEAC 2021) October 25-27, 2021, Sochi, RussiaThe All-Russian scientific conference “Thermophysics and Power Engineering in Academic Centers“ (TPEAC-2021) continues series of conferences (workshops) on thermophysics and heat power engineering. Since the first conference until now, the principal organizer of the conference is the Kutateladze Institute of Thermophysics, SB RAS. The 1st Workshop of the University Departments and Research Teams in Siberia and the far East specializing in thermophysics was held in Novosibirsk in 1978. Since then, the geographical spread of the Conference expanded every year involving various research centers: Tomsk, 1980; Krasnoyarsk, 1982; Vladivostok, 1984; Kemerovo, 1986; Ulan-Ude, 1988. The 7th Workshop was held in Novosibirsk, September 9-12, 1990, at the Institute of Thermophysics SB RAS. Workshop of Universities in Siberia and Far East on Thermophysics and Heat Power Engineering, dedicated to the 85th Birthday of the Workshop founder, academician S.S. Kutateladze, was held in Novosibirsk, October 6-8, 1999, at the Institute of Thermophysics SB RAS, and the Novosibirsk State Technical University (NSTU). Since 1999 new series of workshops started. The 2nd Workshop was held in Tomsk, 2001, at the Tomsk Polytechnic University (TPU); 3rd - in Barnaul, 2003, at the Altai State Technical University; 4th - in Vladivostok, 2005, at the Far-East State Technical University; 5th - in Irkutsk, 2007, at the Irkutsk State Technical University. Since 2009, when the 6th Workshop was held in Krasnoyarsk at the Siberian Federal University, it acquired the status of an All-Russian conference. The 7th All-Russian Workshop of Universities on Thermophysics and Power Engineering was held in Kemerovo, 2011, at the Kuzbas State Technical University; 8th - in Yekaterinburg, 2013, at the Ural Federal University. Since 2015, when the 9th Workshop was held in Kazan, at the Kazan State Engineering University, it acquired the status of an international conference. International Conference “The 10th Workshop of Universities on Thermophysics and Power Engineering“, was held in Moscow, 2017, at the Moscow Engineering University. The 11th All-Russian scientific conference with international participation “Thermophysics and Power Engineering in Academic Centers“ (TPEAC-2019) held based on the Peter the Great St. Petersburg Polytechnic University (SPbPU), Saint Petersburg.List of “Thermophysics and Power Engineering in Academic Centers” (TPEAC 2021) October 25-27, 2021, Sochi, Russia, Editorial Committee, Organizing Committee, Scientific Committee, Members of the Scientific and Advisory Committee and this titles are available in this pdf.
