Abstract

Abstract

In this paper,on the basis of experimental data of two kinds of chemical explosions,the piston-pushing model of spherical blast-waves and the second-order Godunov-type scheme of finite difference methods with high identification to discontinuity are used to the numerical reconstruction of part of an actual hemispherical blast-wave flow field by properly adjusting the moving bounary conditions of a piston.This method is simple and reliable.It is suitable to the evaluation of effects of the blast-wave flow field away from the explosion center.
