摘要

摘要: 就阻抗递变的多层组合飞片对靶样品的冲击压缩过程进行了一维平面应变数值模拟计算，其中，等熵线采用逐步递推法计算。以水和钽为靶的计算结果显示，这种多层组合飞片对水和钽均产生了很好的准等熵压缩效果。其中，对水的计算结果与国外文献报道的结果一致；计算的钽/氟化锂窗口界面速度历史与实验结果十分吻合。因此，用适当匹配的多层组合飞片对靶样品产生准等熵压缩是可行的，提出的准等熵压缩的数值模拟方法是可靠的。

Abstract: This article describes the numerical simulation for shock compression which is produced by layered flyers impacting target, in which the isentropic curve is calculated by recurrence method. Take water and tantalum for examples, the calculation results show this kind of flyers can produce good effects of quasi-isentropic compression for water and tantalum, and the result for water is in accord with the reference data, the calculation results for the interface velocity between Ta/LiF is in accord with the experimental results. Therefore, the method to obtain quasi-isentropic compression by layered flyers impacting target and the method of numerical simulation for quasi-isentropic compression are reliable.
