THE MEAN VELOCITY DISTRIBUTION NEAR THE PEAK OF THE REYNOLDS SHEAR STRESS EXTENDING ALSO TO THE BUFFER REGION

摘要

An expression is derived for the mean velocity distribution in pipe and channel flows near the position of the maximum Reynolds shear stress, ym. This expression agrees well with measurements in a significant region on both sides of ym, extending to the buffer region on the one hand and almost all the way to the centerline of the flow on the other.
