Morozov, A. Smetannikov] The dynamics of the processes proceeding upon explosion of condensed explosives in the air has been investigated. The paper discusses the physical model, the computing method, and the results of modeling a two-dimensional hydrodynamic fl ow initiated by the explosion of a spherical charge at some height above the ground surface. Explosions of charges at a height comparable to the size of the region occupied by the explosion products are considered. The results of calculations have made it possible to obtain a detailed space-time pattern of the initiated fl ow and investigate the incipient formation, propagation, interaction, and subsequent attenuation of shock waves. It has been shown that the distance to the surface can strongly influence the fl ow dynamics and parameters of shock waves.
