A new scaling is derived that yields a Reynolds-number-independent profile for all components of the Reynolds stress in the near-wall region of wall-bounded flows, including channel, pipe and boundary layer flows. The scaling demonstrates the important role played by the wall shear stress fluctuations and how the large eddies determine the Reynolds number dependence of the near-wall turbulence behaviour.

壁面流动近壁区域的雷诺应力缩放

推导了一个新的比例，它为壁边界流动的近壁区域中的雷诺应力的所有分量产生了一个与雷诺数无关的剖面，包括通道、管道和边界层流动。缩放显示了壁面剪应力波动所起的重要作用，以及大涡流如何确定近壁面湍流行为的雷诺数依赖性。
