The vortex heat generators are known as installations that allow converting the liquid stream energy into heat. Currently, there are many manufacturers of heat generators with various declared parameters and characteristics. The authors interpret various scientific hypotheses explaining the hydrodynamic processes occurring in the heat generator, however, only a small number of real experimental studies on this subject representing of great interest are in free public access. This article is devoted to the actual issue of processes modeling the vortex high-pressure fluid flow in the constant volume circuit. The authors consider the physical and numerical modeling of these processes occurring during the fluid flowing in closed channels with throttling of the flow section and high-speed flowing through tangentially directed nozzles in the special chambers. At the same time, thanks to the organization of a swirling flow in special chambers in a closed circuit, an intensive growth of the working fluid temperature is observed; it allows the vortex devices of this type to perform the functions of heat generators. The equations describing the cavitational two-phase fluid flow and the numerical simulation results of the flow in the heat generator using the software complex ANSYS are presented in the article.
