An Effective Viscosity Model for Turbulent Wall Boundary Layers.

Abstract

Existing effective viscosity models which have been very valuable in the mean field closure method for turbulent boundary layer computation have shown certain undesirable limitations for certain realistic but general boundary layer flows. The more general flows usually involve non-negligible considerations of pressure gradients and such wall conditions as roughness, curvature and aspiration or transpiration in varying degrees of importance. The effects of these external and wall influences are included in the present model of the effective viscosity which is developed for a general flow. (Author)
