- Аннотация: https://elibrary.ru/item.asp?id=44569624The evolution of the structure of a self-similar flow for various types of negative Mach reflection with a change in the governing parameters of the problem (the Mach number of the incident shock wave, the gas adiabatic index, and the wedge angle) was studied. Along with the known modes of double and triple Mach reflection, a qualitatively new self-similar mode of “multiple” Mach reflection with four or five three-shock configurations was observed and investigated. Various modes of negative Mach reflection in the presence of perturbations: a thin layer of low density near the surface of the wedge are investigated.The study was performed in accordance with the research plan of the Research Institute of Mechanics of the Moscow State University named after M.V. Lomonosov (topic АААА-А19-119012990113-1) with the financial support of the Russian Foundation for Basic Research (project 18-01-00793).
