Abstract:

含铝炸药的爆轰过程属于典型的非理想爆轰过程,其波头反应区处于多相反应流动状态,因此其波头处爆轰参数的计算一直是一个难点。在假定铝颗粒于波头处不参与化学反应且爆轰产物和铝颗粒压力、速度一致的条件下,应用连续介质模型描述了爆轰产物和铝颗粒两相之间的平衡关系,采用广义C-J条件给出了计算波头处爆压、物质速度和爆热的一组简单完备方程组。由实测得到的爆速,可以求得相应的爆压、物质点速度和波头处释放的热量。对三组不同含铝量(10%,20%,30%)的TNT含铝炸药和HMX含铝炸药的计算结果表明随着爆速的降低,对应的爆压、波头处物质速度和热量都会降低,不同含铝量的同一炸药在同一爆速条件下,含铝量越高对应的爆压值、波头处爆热值越大。同时,对计算假定和采用模型进行了一定的讨论。
