✦ Synopsis

This paper reviews some recent research aiming to assess the performance of advanced forms of second-moment closure and nonlinear eddy-viscosity models for compressible ¯ows, with particular emphasis placed on strong shock-boundary-layer interaction involving separation. This topic is of particular relevance to high-speed aerospace and turbomachinery aerodynamics. Relevant closure forms and their merits, relative to simpler linear eddy-viscosity approximations, are reviewed ®rst, mainly in qualitative terms. The performance of some particular models is then examined by reference to solutions for a range of 2D and 3D compressible ¯ows.

A nonlinear low-Reynolds-number k-e model of was extended to predict the flows over a step with inclined wall, where a boundary-layer flow without separation and a separated and reattaching flow coexist. For a better prediction of the flows, a slight modification was made on the function of wall da
