An impinging jet is a fluid jet that strikes a surface vertically or at a specific angle for cooling or heating. In this case, the post-impact flow develops on the surface, creating a thermal boundary layer. As it moves in a peripheral direction, the thickness of this boundary layer increases, and consequently, the rate of heat transfer … http://www.1cae.com/a/ansys-fluent/45/fluent-dpm-ansys-3285.htm tsn plc-8
