The history of conferences related to the ﬂow swirling dates back to the cycle of All-
Union scientiﬁc and technical conferences "Vortex effect and its application in technology" held in Kuibyshev (Samara) from 1971 to 1993.
The idea of exchange of views and contacts of specialists engaged in the study of swirling ﬂows was enthusiastically met by the scientiﬁc community of post-Soviet Russia and was picked up by the corresponding member of the RAS, Yu. V. Polezhaev, who proposed to organize The First Russian conference "Swirling ﬂow to improve the efﬁciency of heat exchangers" in Moscow, at the Joint Institute of High Temperatures of the Russian Academy of Sciences from 9 to 11 April 2002. A total of 23 reports by leading Russian teams were presented at the conference.
The second Russian conference "Heat and mass Transfer and hydrodynamics in swirling ﬂows" took place on March 15-17, 2005 at the Moscow Power Engineering Institute (MPEI) and was dedicated to its 75th anniversary. About 100 reports have been presented there. At the Third and Fourth international conferences held at MPEI in 2008 and 2011., there were six sections, 120 and 150 reports, respectively. Lectures were given by leading scientists: A. E. Bergles (USA), John R. Lloyd (USA), V. I. Terekhov (Russia), D. B. Spalding (UK), N. Syred (UK), A. A. Khalatov (Ukraine), E. D. Fedorovich (Russia), etc.
The fifth and sixth conferences were held in Kazan (KNRTU-KAI) and Novosibirsk (IT SB RAS) in 2015 and 2017. Along with well-known Russian and foreign scientists, a large number of young scientists presented their reports. The Seventh international conference "Heat and mass transfer and hydrodynamics in swirling ﬂows" was held to Soloviev Rybinsk State Aviation Technical University (RSATU).
The purpose of the international conference "Heat and Mass Transfer and Hydrodynamics in Swirling Flows" is to present current scientific achievements in the field of heat and mass transfer intensification, the study of complex flows, experimental, analytical and numerical modeling of heat and mass transfer and hydrodynamics processes at the macro -, micro-and nanoscale.
The working languages of the conference are English and Russian.
