For the optimization of arc ash melting process, present study has proposed the new numerical model to consider the arc-electrodes boundary condition without assumptions and also the complex interactions between the arc flow and molten soil interface with phase change. The effects of arc current, inlet gas flow rate, electrode gap and cathode vertex angle on the thermofluid field and net effective process efficiency of arc-ash melting systems are clarified by computational simulation.
