Abstract :
Numerical simulation of unsteady turbulent flow for a rectangular impinging jet is carried out in this paper. The Nusselt number at stagnation point increases as nozzle to plate distance (H/D) increases until H/D=8. This may be caused by nonlinear dynamic effects in momentum and energy transport within the boundary layers. The flow and temperature fields in one period have been compared. The temperature fields only change a little with the presence of vortex produced by rectangular impinging jet.
