摘要: 本文用特征线方法计算了一维非定常炸轰的发展和传播问题。为模拟炸药的化学反应,采用了一种冲击波引爆的唯象模型。以PBX-9404高级炸药为例给出了计算的POP图与实验结果的比较以及不同时刻波后流场的分布。

Abstract: A phenomenological model of shock initiation and detonation of heterogeneous explosives is implemented in the one-dimensional hydrodynamic code based on the method of characteristics. Since there is no artificial viscous term to smear the shock, we can get a clear picture of the simulated structure of detonation wave. We have calculated Unsteady detonation process of PBX-9404 and the results are quite well consistent with the experiment data.
