摘要: 介绍了在强脉冲电流的作用下双层钨衬套Z箍缩动力学过程的数值模拟,计算了一个双层钨衬套模型,分析了双层衬套的碰撞过程,指出了双层衬套下电磁内爆的现象和特点,给出了碰撞后电流在内外衬筒上的分布,并对箍缩功率和箍缩产生的能量进行了预估。Abstract: We have worked out one dimensional double region MHD programs for Z-pinch simulation. One of our calculated results of tungsten load has been discussed in the article. The dynamic phenomenon of double wire pinch is presented. The current distribution between the two liners after collision was given. According to our simulation results, 120 GW of X-ray power and 1.0 kJ of X-ray energy are produced in the pinch.
