摘要

采用改进的流体力学方法研究了磁压力作用下等离子体开关的运动特性。与NRL的模拟代码不同的是,将等离子体填充区划分为N个部分,并使用实验测量的电流穿透参数。根据磁绝缘真空间隙形成的侵蚀机理,对开关开断相进行了模拟。该代码包括双发电机内(电位)电极负极性运行状态的规则电路数据。在典型的传导相位持续时间(900纳秒)的情况下,发现所需的最小等离子体密度约为1015厘米。传导电流幅值与等离子体密度的最佳拟合为I ~ n0.23。计算得到的开关开断相位特性与实验数据非常接近。

Numerical simulations of plasma dynamics in a microsecond plasma opening switch
The modified hydrodynamic approach is being used to study the characteristics of plasma motion due to magnetic pressure in plasma opening switch. The simulation code differs from the NRL counterpart with dividing of the plasma filled region into N sections and with using the experimentally measured current penetration parameters. The simulation of the switch opening phase is performed in terms of erosion mechanism of magnetically insulated vacuum gap forming. The code includes the circuit data which are regular for the DOUBLE generator operation regimes in the negative polarity of inner (potential) electrode. In the case of typical duration of the conduction phase (900 ns) the-minimum needed plasma density was found to be about 1015 cm. The best fit of conduction current amplitude vs plasma density is I ~ n0.23. The calculated characteristics of the switch opening phase were obtained to be very close to the experimental data.
