A COMPARISON OF SEVERAL EDDY VISCOSITY TURBULENCE MODELS IN 2 AND 3-DIMENSIONAL BOUNDARY-LAYER FLOWS

Four flow cases are calculated using a boundary layer method with five turbulence models. The Johnson-King model, in particular, is modified and two variant forms are used in the present work. The variant forms involve an anisotropic form of three-dimensional eddy viscosity formu lations and a modification in the outer viscosity expression. It is fo und that the Johnson-King model generally performs very well as compar ed to the others, and the variant forms provide further improvement in most cases.
