This paper focuses on the numerical simulation of the arc plasma behavior considering eddy currents in electrodes and splitter plate. Eddy currents in metal parts are generated by time-varying magnetic field in arc moving and splitting process. Based on a three-dimensional (3D) magneto-hydrodynamic (MHD) model, the elongation and splitting process are simulated. A thin layer of nonlinear electrical resistance elements is used to represent the voltage drop of plasma sheath and the formation of new arc roots. So the arc splitting process with ferromagnetic plates can be included. The effect of ferromagnetic material。ッs nonlinear permeability is involved in the calculation. The temperature, velocity and current density distribution is calculated and analyzed in detail. And the calculated arc voltage is compared with the results neglecting eddy currents. |
