Abstract

Magnetically dispersed arc plasma^[1] exhibits typically dispersed uniform arc column as well as diffusive cathode root ^[1,2] and diffusive anode root. In this paper magnetically dispersed arc plasma coupled with solid cathode is numerically simulated by the simplified cathode sheath model of Lowke
[3]. The numerical simulation results in argon show that the maximum value of arc root current density on the cathode surface is 3.5×10⁷ A/m², and the maximum value of energy flux on the cathode surface is 3×10⁷ J/m², both values are less than the average values of a contracted arc, respectively.
