在一维流体动力学编码SSS程序中,利用三项式点火增长反应速率模型对钝感炸药JB-9014的反应区进行了计算。计算中,未反应炸药采用固态HOM状态方程,产物采用气态JWL状态方程,计算得到了钝感炸药JB-9014化学反应区的峰值压力、CJ压力、反应区宽度和反应时间等参数,计算结果与实验结果符合较好。分析表明,三项式点火增长反应速率模型可用于研究钝感炸药的反应区结构。 相似文献

Interaction of Shock Waves in Cement Mortar Plate Investigated by the Digital Speckle Correlation Method 下载免费PDF全文
Interaction of shock waves in cement mortar plate is studied by digital speckle correlation method and digital high-speed photography technique. When the plates were destroyed by two detonators exploding at the same time, variation of shock wave field is obtained. Experimental results show that the interaction of shock waves will result in a nonlinear huge increase of local normal strain, leading to large deformation and serious destruction. However, the occurrence of this strongly nonlinear phenomenon sensitively depends on the interval between detonators, and it will only appear when the interval is smaller than the diameter of the region where shock waves exist. 相似文献
