摘要
基于MOCL(MarkonCellLine)分界面跟踪算法 ,用二维多流体网格法的欧拉程序 ,数值模拟了锥形罩聚能装药侵彻钢板的全过程 ;与试验结果进行了比较 ,可以满足工程设计的需要。这种连贯性的模拟能力避免了数值计算中对射流的许多人为假定 。
Based on MOCL algorithm, the full process penetrating a 10 mm thick steel slab by a shaped charge is numerically simulated in a two-dimensional multi-material Eulerian code. The results are compared with the experimental data, which are able to be applied to engineering design. The ability to coherently simulate the full process can avoid lots of artificial hypotheses to the jet in the numerical computation, and is of practical value to simulate numerically terminal effects of a series projectile.
