The development of instability of Richtmyer–Meshkov in the interaction of a shock wave with a two-component medium consisting of light and heavy gas

Abstract

Abstract On the basis of the previously formulated mathematical model of the mechanics of a two-speed two-temperature mixture of light and heavy gases, the evolution of a system of two cylinders of heavy gas after the passage of a shock wave through it is numerically investigated. The analysis of the obtained data on the dependence of the spatial expansion on time, as well as the kinematic characteristics of the system showed their satisfactory compliance with the experimental data for all initial separations of the cylinders. The influence of the initial separation of cylinders on the flow morphology is investigated.
