Abstract :
Summary Form only given, as follows. A mathematical modeling program has been initiated to provide computational capabilities applicable to process development, equipment design and process control of plasma reactors for molten-bath plasma furnace melting. The mathematical model developed fully addresses the conjugate heat transfer, phase change, and boundary condition aspects of the problem and provides numerical solutions to the governing equations. The relative influences of thermal buoyancy and thermocapillary and arc-shear-induced flow on both the melt-pool volume and skull profile have been examined, and interactions between the flow effects have been analyzed.<>
