| 摘 要： | 采用多流体Ｕｕｌｅｒ型方法，对爆轰产物采用可变指数的多方气体状态方程，给出了对二维爆炸场进行模拟的方法，该法可为用压力一冲量准则对可能发生的爆炸事故进行风险评估提供基础。数值计算结果表明，该法适合于各种不同的几何外型，与现有实验结果符合较好。

| Abstract: | This paper presents a numerical method based on multi --fluid Eulerian algorithm tosimulate two dimension explosion field, in which perfect gas equation of state having variableindex is used for explosive. This method can be applied to hazard evaluation for explosion byaccident using pressure--impluse criterion. The results of numerical computation, which areagreed to experiment results, show that the present method is suitable for different geometries. |
