High Temperature Hydrodynamics of Explosion and Shock Wave Phenomena
A. S. Smetannikov and A. V. Teterev

Hydrodynamics of processes occurring in some problems of high energy density physics is considered. Physical models, computation technique and results of simulation of a hydrodynamic flow are discussed. For the description properties of material in hydrodynamic calculations a wide-range equation of states has been used. The following problems have been considered: explosion of an explosive charge above surface, high-velocity meteorite impact on protection shields and falling of space bodies in a water basin. The results of simulations allow one to obtain a detailed spatial-temporal distribution of the arising flow and to study origination, propagation, interaction and attenuation of shock waves.

Key words: high energy density physics, numerical modeling, hydrodynamic flow, equation of state
