| Abstract: | In this paper, the random choice method (RCM) with an operatorjplirting technique is applied to the numerical simulation of shock propagation down an area change tube with a nonuniform steady flow and flow properties behind the shock. The change rules of the shock strength and flow properties behind it haver been obtained, and the results are analysed preliminarily. |
