Abstract

Numerical computation with Transition k-kl- model is conducted to investigate the heat transfer characteristics for the single jet impingement cooling. The effects of the jet Reynolds number and the impingement spacing (jet-to-surface spacing, Zn/D) on heat transfer characteristic are researched. Results show that the numerical predictions are in good agreement with the analytical solution and experiment data. The maximum value of the Nusselt number is located in X/D=0.75. The bigger Reynolds number is, the better cooling effect is. There exists an optimal impingement spacing for heat transfer effect, the Nusselt number could reach the highest value in Zn/D=4.
