Abstract: For this paper, based on two phase flow model of dilute partical suspension in a gas,the GRP scheme of finite difference method with high resolution and the second order Mac Cor mack sche me are applied to the numerical analysis of the propagatfon of spherical shock waves in dusty gas for four kinds of initial states. The results indicate that the propagating process of spherical shock waves and the flow field developed behind it possess more complicated properties as compared with that in a pure gas. The r...
