摘要

摘要: 采用磁流体力学的方法对等离子体端路开关进行了一维数值模拟，通过对给定的进入等离子体的电流波形模型的计算，给出了轴向上等离子体的运动及其不同时刻的密度分布，分析了磁场在等离子体内部的异常渗透过程，指出考虑Hall效应是产生这一异常现象的最为主要的因素。

Abstract: Preliminary results of an one-dimensional numerical code designed to investigate the magnetic field thrust effects in plasma opening switch are presented. The code is based on the magneto-hydrodynamic equations, and the current into the switch is given as a known condition. The plasma development on the axial direction is calculated. Also plasma density at different moment during the opening process is described. It is pointed out that the Hall effect plays a predominant role in the abnormal penetration of magnetic field.
