We invite you to take part in the IX All-Russian Conference “Thermophysics and Physical Hydrodynamics” (TPH2024) and the scientific youth school “Thermophysics and Physical Hydrodynamics: modern Challenges” (TPHMS2024). The conference is devoted to the fundamental problems of modern thermophysics and hydrogas dynamics and is a continuation of a series of All-Union conferences of young researchers held with the participation of the Institute of Thermophysics SB RAS (Novosibirsk) since the 1970s. The conference will be held from September 8 to 15 at the Aquagrad Hotel, Sochi. The conference is organized by leading scientific institutes and universities of Novosibirsk. The purpose of the conference is to discuss modern problems in the field of thermophysics and hydrogas dynamics, to find ways to solve them, as well as to prepare a highly qualified scientific personnel reserve and attract young scientists to the most relevant research.
