Abstract

Abstract: The coupling computation method which combines numerical solution and analytical one is used in simulating the annular jet formation and penetration into the target. The actual results indicate that this is the method is of having better computational precision and saving lots of computational time. It can be applied in the design of shaped charge.

Key words: annular jet, W shaped charge, MOCL, numerical simulation

摘要： 运用带有MOCL分界面跟踪算法的二维多流体欧拉程序和解析解相耦合的算法数值模拟了环形射流的形成及其对靶板的侵彻。实际应用表明，此方法计算结果准确可靠，经济省时，对聚能装药的优化设计具有较高的效费比。
