Abstract

Abstract

The jet plume formed immediately adjacent to the nozzle of an arc spray gun has a significant effect on the properties of the resultant coating. This study applied the computational fluid dynamics (CFD) and the Schlieren photography to elucidate the properties of jet plumes. The Schlieren images examined revealed that the properties and widths of the plume depend on the direction of material wires for thermal coating. Through the CFD approach, we observed the formation of shock waves immediately after the nozzle aperture and damping of the shock waves in the downstream plume.
