Anomalous Effects of Pressure Gradient on Supersonic Turbulent Boundary Layers

摘要

Consistent discrepancies between calculations and experiments on supersonic boundary layers in moderate to strong pressure gradients are considered. It is thought that these are due to unexpected, large effects of mean dilation on the Reynolds stresses. Agreement between calculation and experiment is greatly improved by representing the effects of mean dilation in the same way as that used to represent the effects of extra rates of strain in low-speed flows.
