Abstract
For the optimization of arc ash melting process, the present study has proposed the new numerical model to consider the arc flow boundary conditions without using experimental data and also the complex interactions between the arc flow and molten soil interface with phase change. Next, the effects of arc current, electrode gap, inlet gas flow rate and cathode vertex angle on the thermofluid field of arc-molten soil system are clarified by numerical simulation to provide the fundamental data for optimum operating conditions and melter configuration of arc ash melting process.
