Abstract: In this work, Magnetic Hydrodynamic (MHD) model is used to simulate heat transfer and fluid flow in a DC Plasma-Arc reactor for waste thermal treatment. Through the coupled iterative computation about electromagnetic equations (using magnetic vector potential) and hydrodynamic equations, the temperature and velocity distributions are solved, which are the most valuable information for industrial application. The simulation results clearly describe the phenomenon of high temperature cathode jet of plasma-arc. The gas around arc region is heated and driven to flow by cathode jet. The situation of heat transfer and fluid flow is obtained, which is expected to meet the requirements for industrial application of hazardous waste treatment with the plasma-arc technology.
