摘要：

Direct numerical simulation of flow and heat transfer behind a spanwise rib mounted in a channel has been performed in steady and pulsating flow at the Reynolds numbers corresponding to transition to turbulence in the separation region behind the rib in the steady flow case. Numerical simulation results have been verified. Good agreement between the numerical and experimental flow patterns, profiles of velocity and velocity fluctuations in the rib wake has been demonstrated. The effect caused by forced unsteadiness parameters on heat transfer has been analyzed on the basis of numerical simulation results. Correlation between heat transfer characteristics and vortical structure of flow behind the rib has been revealed. It has been shown that heat transfer in transitional regimes of the rib flow in the channel can be further enhanced by forced flow pulsations.
