On the basis of a mathematical model of the mechanics of a two-velocity two-temperature mixture of light and heavy gases with different pressures, the dynamics of a heavy-gas droplet in the case of incidence of a shock wave on it is numerically studied within the framework of two-dimensional nonstationary flow of the mixture. An analysis of experimental data on the dependence of the spatial expansion of the droplet on time has shown their satisfactory agreement with calculated data.
