| 摘 要： | 文章通过数值模拟方法,对B炸药-铝、B炸药-铜系统中爆轰波斜反射现象进行了研究,获得了介质分界面处压力随入射角度变化规律,并确定了发生膨胀反射时的临界入射角度。计算结果与前人的实验观测结果吻合。本模拟计算的金属中形成的冲击波压力比基于理想爆轰假设的理论结果更符合实际,计算精度可满足工程应用需求。

| Abstract: | The oblique reflection phenomena of detonation waves occurring at B explosive-aluminum and B explosive-copper system was investigated by means of numerical simulation;the changes of the pressure at the interface with the incidence angles was found,and the critical angle of Prandtl-Meyer flow where has to happened was got.Calculation results coincided well with the experimental results of former literatures.The study indicates that the simulation result is more conformed to the reality compared with traditio... |
