摘要

结合表面更新和经典理论，初步分析了壁面内输运过程与湍流核内输运过程的根本区别。结果表明，在离壁较近的地方，Prt随Pr增大而增大，而在离壁较远的地方，Prt随Pr减小。

A model of the turbulent burst phenomenon: Predictions for turbulent prandtl number

A preliminary analysis is developed coupling surface-renewal and classical ideas which accounts for the fundamental difference between the transport process within the wall region and the turbulent core. It shows that Pr_t increases with Pr very near the wall, but decreases with Pr at greater distances from the wall.
