摘要: 为了满足串联战斗部中一级弹开坑的要求,本文提出并设计了能够形成环形射流的W型聚能装药,运用带有网格线示踪点法(MOCL)分界面跟踪算法的二维多流体欧拉程序,对环形射流的形成进行了数值仿真,比较数值仿真结果与试验结果,该聚能装药可以满足工程设计的要求。

Abstract: A W shaped charge is used to form an annular jet that can punch large holes in targets. Ihe process of annular jet formation and of penetrating targets is numerically simulated with a two dimensional Euler program making use of the tracking algorithm with MOCL interface. The results of numerical simula?tion are analyzed and compared with experimental results. It is believed that the design can meet the re?quirements in engineering design.
