摘　　要：采用多物质欧拉算法 ,对近水面爆炸进行模拟 ,计算爆轰产物、水、空气的相互作用过程 ,得到各流体介质压力、密度等物理量的变化规律以及水柱的形成发展过程。该方法用来分析复杂流体的运动可以得到较好的结果。By applying multi-material Euler algorithm, a simulation of explosion near water surface is conducted, and the calculation of the multi-material interactions between water, air and exploded substance for near water surface explosion is presented. The changing regularities of fluid's pressure and density as well as the developing course of water-column have been obtained. The results show that this method is efficient to analyze complex movement of fluid.
