摘要：
Direct numerical simulation of flow and heat transfer behind a spanwise rib in a pulsating flow in a channel has been performed at the Reynolds numbers that correspond to transition to turbulence in the separation region behind the rib in a steady flow case. Good agreement between the calculations and experimental data has been demonstrated. The effect of forced unsteadiness parameters on heat transfer behind the rib has been analyzed. It has been shown that forced flow pulsations are able to augment heat transfer. The correlation between the heat transfer level and the vortical structure of flow behind the rib has been demonstrated.
