A Survey of Measurements and Measuring Techniques in Rapidly Distorted Compressible Turbulent Boundary Layers


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.

Compressibility, Turbulence and High Speed Flow


Book Description

Compressibility, Turbulence and High Speed Flow introduces the reader to the field of compressible turbulence and compressible turbulent flows across a broad speed range, through a unique complimentary treatment of both the theoretical foundations and the measurement and analysis tools currently used. The book provides the reader with the necessary background and current trends in the theoretical and experimental aspects of compressible turbulent flows and compressible turbulence. Detailed derivations of the pertinent equations describing the motion of such turbulent flows is provided and an extensive discussion of the various approaches used in predicting both free shear and wall bounded flows is presented. Experimental measurement techniques common to the compressible flow regime are introduced with particular emphasis on the unique challenges presented by high speed flows. Both experimental and numerical simulation work is supplied throughout to provide the reader with an overall perspective of current trends. - An introduction to current techniques in compressible turbulent flow analysis - An approach that enables engineers to identify and solve complex compressible flow challenges - Prediction methodologies, including the Reynolds-averaged Navier Stokes (RANS) method, scale filtered methods and direct numerical simulation (DNS) - Current strategies focusing on compressible flow control
