Numerical analysis of cylindrical shock waves in heterogeneous environments

Abstract

In this paper, a numerical study of propagation of cylindrical shock wave and its interaction with the adjacent layer of a heterogeneous two-phase medium is held. To solve the conservation equations of two-phase medium was used a modification of the method of Neumann-Richtmyer, adapt to calculations for heterogeneous environments. The complexity of the calculation of flows containing discontinuities such as shock waves dues to the necessity of translation computational grids in the high pressure gradients. Set of problems: the construction of a mathematical model of two-phase medium, the modification of the numerical method of calculation algorithms for restructuring computational grids are presented in the form of a complete computer technology, which effectively carry out calculations for the dissemination of multi-dimensional problems of strong discontinuities in heterogeneous environments.
