目的 研究二维爆炸场中爆轰产物和空气冲击波绕流的物理机制方法 基于多物质流体的Euler型算法,对爆轰产物采用JWL状态方程,自行编制了SMMIC通用程序结果 通过大量的计算工作,得到了在爆炸点周围有和无防护挡墙的二维爆炸场的初始发展过程和绕过障碍物的情况结论 计算结果基本符合冲击波绕过防护挡墙的物理现象和规律,说明该物理模型和数值算法较为合理。
Aim To study the mechanism of the flow of the explosive shock wave around the protective wall. Methods Based on the algorithm the Euler type MMIC, the SMMIC code was made by using the JWL equation of state for the explosive product. Results The initial stage of the development of 2 D explosive field with and without the protective wall was obtained. Conclusion The results which the shoch waue moues around the protective wall are in agreement with the principle of physics. It also indicates that the model and algorithm presented is proper and it can be used to aid the project design and simulate the problems about the effect on the far field by the explosion.
