Modelling shock-affected near-wall flows with anisotropy-resolving turbulence closures

This paper reviews some recent research aiming to assess the performance of advanced forms of second-moment closure and non-linear eddy-viscosity mode ls for compressible flows, with particular emphasis placed on strong shock- boundary-layer interaction involving separation. This topic is of particula r relevance to high-speed aerospace and turbomachinery aerodynamics. Releva nt closure forms and their merits, relative to simpler linear eddy-viscosit y approximations, are reviewed first, mainly in qualitative terms. The perf ormance of some particular models is then examined by reference to solution s for a range of 2D and 3D compressible flows. (C) 2000 Elsevier Science In c. All rights reserved.
