| 摘 要： | 利用ALE算法和炸药爆轰产物的JWL状态方程对爆炸冲击波绕过墙体的环流现象进行了数值模拟，得到了在爆炸物周围有障碍物的爆炸场初始发展和绕过墙体环流的情况，解析了空气冲击波的绕流规律。实验结果与数值模拟基本相符，反映了爆炸波绕过障碍物的详细过程。

| Abstract: | Using ALE algorithm and the JWL,state equation for the product of explosive shock wave,the numerical simulation of the shock wave rounding the wall was conducted.The initial development of explosive field and the circulation current behavior were obtained and the law of shock wave rounding the wall was analyzed.Both experimental and numerical results were in good agreement,which showed the inherent mechanism of blast wave rounding the wall. |
