一维理想磁控等离子体激波管流动仿真

One dimension numerical simulation of the ideal plasma controlled by the external magnetic field in the shock tube

推导了磁场作用下等离子体流动的控制方程,采用加入人工粘性项的MacCormack二阶格式对方程进行了离散。计算了在不同磁场作用下,一维理想磁控等离子体在激波管内的流动情况。计算结果表明,在施加磁场作用后,激波管内的波系结构发生了明显的改变,磁场强度在激波的影响下发生了重新分布。

The governing equations of the plasma flow controlled by the external magnetic field were derived. The second order Maccormack scheme included artificial viscosity was used to get the discrimination of the governing equations. One dimension ideal plasma flow in the shock tube at different magnetic fields was simulated. The results show that the structure of the shock waves in the shock tube change remarkably as the external magnetic field exists. The magnetic field redistribute on the influence of the shock waves.
