THE PROPAGATION OF SPHERICAL SHOCK WAVES IN DUSTY GAS
粉尘气体中的球激波

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 results showed that the numerical method applied in this paper can get resolution with high accuracy,nonoscillation and sharp discontinuity.
