Book Description

This AGARDograph presents a wide range of recent work on compressible turbulent boundary layers. Special attention has been paid to flows with rapid changes in pressure including flows with shock waves, curved walls and expansions. Recent developments in the theory and experimental practice for these flows are presented. The application of rapid distortion theory to flows traversing expansion and shock waves is reviewed. This is followed by an account of experiments in progress aimed at elucidating the large scale structures present in supersonic boundary layers. The current status of the techniques of Laser-Doppler and Hot Wire anemometry in supersonic flow is discussed, and a new interferometric technique for the determination of wall-stress is described. The use of small pressure transducers to deduce information abut the structure of zero pressure-gradient and severly perturbed boundary layers is investigated. Finally there is an extension of the review and data presentation of AGARDographs 223, 253 and 263 to cover some of the experiments dealing with rapidly distorted layers.
