摘要
In this study PLASIMO program developed by Eindhoven University of Technology was used to investigate the effects of argon flow velocity on argon plasma in the cascaded arc. The simulation results are in good agreement with available experimental data that along the symmetry axis, the pressure decreases but the electron temperature increases from the inlet to the outlet. The effects of flow velocity of argon on plasma properties were investigated. The simulation results show that for argon arc discharges, with increasing the flow velocity, the electron density and the heavy particle temperature increases, while the electron temperature decreases. Along the symmetry axis, the electron temperatures are all above 1 eV and the heavy particle temperatures are all about 1 eV at different flow velocities.
