摘要

基于离子、电子和麦克斯韦方程两种流体模型，建立了真空电弧的二维磁流体力学模型，该模型考虑了质量守恒方程、动量守恒方程、能量守恒方程、麦克斯韦方程和广义欧姆定律。通过对上述方程的数值计算，得到了真空电弧的等离子体参数。根据计算结果，分析了方位自磁场和不同径向分布轴向磁场的影响。(AMF)对真空电弧等离子体参数的影响。

MHD simulation of vacuum arc under different AMF

Based on two-fluid models of ion, electron and Maxwell equation, The two-dimensional magnetohydrodynamic (MHD) model of vacuum arc was obtained in this paper, In the MHD model, mass conservation equation, momentum conservation equations, energy conservation equations, Maxwell equation and generalized ohm¿s law were considered. By numerically calculating above equations, the plasma parameters of vacuum arc were obtained. According to the calculation results, The influence of azimuthal self-magnetic field and different radial distributed axial magnetic field. (AMF) on vacuum arc plasma parameters were analyzed.
