摘要: 本文在瞬时稳态爆轰的假定下,简要叙述了散心爆轰的不定常性质。在散心爆轰的数值模拟方法中,我们改进了人造粘性并用Cochran反应率和JWL状态方程来描述炸药的引爆过程。计了几个典型的散心爆轰问题,得到了比较满意的结果。

Abstract: In this artical a unsteady nature of divergent detonation wave has been briefly describees with the assumption of instantaneous steady detonation. In the method for numerical modeling of divergent detonation we have improved artificial stickiness and described ignition process of explosive with cochran's reaction rate and JWL equation of state. A few of typal divergent detonation problems have been Calculated with our 2DL program and Some satisfactory results have been been gotten.
