| 摘 要： | 从非定常Ｅｕｌｅｒ方程出发，用高精度高分辨率的ＴＶＤ格式，对圆柱形空腔内的气云爆炸波对壁面作用问题进行了数值模拟。计算获得圆柱形空腔内气云爆炸场的复杂的波系结构及其演化过程、壁面任意指定点的压力时间曲线。本文还给出了同体积、不同形状的气云爆炸对壁面的作用效应。

| Abstract: | Based on unsteady Euler equations, high accuracy and highresolution TVD scheme was used to simulate the cloud explosion in a cylindrical confined volume. Complicated blast waye structure, blast wave'sdeveloping and pressure time history at arbitrary given points on the innerwall are obtained in this paper. Some numerical experiments of vapourcloud explosions with different shapes and their impact to inner wall ofcontrolled volume were also be done. |
