N2 - Based on MHD model, high current vacuum arc (HCVA) is simulated and analyzed. In this model, the influence of ion kinetic energy and viscosity is considered. With the increase of arc current, plasma flow transits from supersonic to subsonic status; so, boundary conditions of cathode and anode side have to be adjusted. First, we simulate and analyze the fundamental characteristics of HCVA. Then, we simulate and analyze the influence of nonuniform distributed AMF on HCVA characteristics. According to the simulation results, the saddle-shaped AMF can more effectively inhibit plasma loss from arc column than that of bell-shaped AMF. Comparisons between simulation results and experimental results show the lightness of model and simulation.
