Two-Dimensional Turbulent Separated Flow. Volume 1

Abstract

Many different flow cases with nominally two-dimensional turbulent separated flow regimes are discussed. Because of intermittent flow reversal and backflow near the wall, directionally sensitive measurement techniques such as hot-wire, pulsed-wire and laser anemometry are discussed. Experimentally- observed structure of detached flows on streamlined surfaces and around sharp- edged corners is discussed for steady and unsteady incompressible and compressible cases where large-scale structures dominate the flow behavior. A number of differential and integral calculation methods are discussed. Traditional attached flow turbulence models do not describe detached flows well and methods which include experimentally-observed features of detached flow parameters seem to perform best.
