SINGULAR PERTURBATION AND TURBULENT SHEAR FLOW NEAR WALLS

For the postulated expansions, the logarithmic profile, wall friction law, and classical similarity results are deduced without an explicit closure condition relating the turbulent stress to the Newtonian stress. Continuation to higher order is shown to be in general indeterminate without additional physical input to the formulation. In an appendix, if the explicit closure of Clauser's eddy-viscosity model is adopted, it is shown how other asymptotic methods (WKBJ-like procedures) readily yield satisfactory results for the defect velocity profile without numerical integration.
