- Аннотация: https://elibrary.ru/item.asp?id=44344472On the basis of the Euler equations for a perfect gas with an inhomogeneous distribution of molar mass, the interaction of a shock wave in a combustible gas with an elliptic bubble of an inert gas of elevated density is simulated in planar two-dimensional (2D) formulation. Various values of the Mach number M of the incident wave and the ratio of bubble axles are considered. A finite-volume Godunov-type method of the second order of approximation with HLLC (Harten-Lax-van Leer Contact) Riemann solver is used for numerical simulation. The combustion reaction of the gas mixture is modeled using the two-stage Korobeynikov-Levin kinetics.This study was performed in the Institute of Mechanics of M. V. Lomonosov Moscow State University (MSU) using the equipment of the shared research facilities of high-performance computing resources of MSU with partial financial support of grants council of the President of the Russian Federation (project No. MK-3012.2019.1) and RFBR (project No. 18-01-00793).
