A new nonlinear near-wall turbulence model is developed on the basis of realizability constraints to predict turbulent flow and heat transfer in strongly nonequilibrium flows. The linear k-e-f l model of Park and Sung (Fluid Dyn. Res., 20 (1997) 97) is extended to a nonlinear formulation. The stress

The effects of the convex surface curvature on the local heat transfer from an axisymmetric impinging jet were investigated. The flow at the nozzle exit has a fully developed velocity profile. The jet Reynolds number (Re) ranges from 11,000 to 50,000, the dimensionless nozzle-to-surface distance (L/

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

Generalized wall functions in application to high-Reynolds-number turbulence models are derived. The wall functions are based on transfer of a boundary condition from a wall to some intermediate boundary near the wall (usually the first nearest to the wall mesh point but that is not obligatory). The
