This numerical study is about the heat transfer in a turbulent flow over a shallow cavity. Two different incoming flows are considered: a boundary layer flow and a plane wall jet flow. The latter is characterized by the presence of an outer layer, an additional turbulence source. In the boundary layer case, the Reynolds number and the turbulence intensity were investigated, while in the wall jet case, the ratio of the cavity depth to the jet nozzle height was examined. The results of this study reveal that the cavity flow is very sensitive to the incoming flow characteristics; an increase of the turbulence intensity accelerates the shear layer reattachment and enhances the heat transfer. The Reynolds number increase also improves the heat transfer. In addition, a heat transfer enhancement was observed in the wall jet case.
