Application of a New K-tau Model to Near Wall Turbulent Flows

Abstract

A recently developed K-tau model for near wall turbulent flows is applied to two severe test cases. The turbulent flows considered include the incompressible flat plate boundary layer with the adverse pressure gradients and incompressible flow past a backward facing step. Calculations are performed for this two-equation model using an anisotropic as well as isotropic eddy- viscosity. The model predictions are shown to compare quite favorably with experimental data.
