Abstract

Modeling study is performed to compare the flow and heat transfer characteristics of laminar and turbulent argon plasma jets impinging normally upon a flat plate (workpiece) in ambient air. It is found that when the plate standoff distance is comparatively large, the effect of the plate on the jet parameters only appears in the region near the plate, and the axial decaying-rates of the plasma temperature and axial velocity along the axis of the laminar plasma impinging-jet are appreciably less than their turbulent counterparts. The radial wall jet formed on the plate surface appreciably enhances the mass How rate of the ambient air entrained into the laminar or turbulent impinging plasma jet.
