Turbulence models for wall boundary layers

Boundary-layer equations with boundary conditions corresponding to a wide range of plane, two-dimensional flows, including the 14 mandatory test cases of the 1968 AFOSR-IFD-Stanford Conference and those over the sub-and supercritical airfoils of Nakayama, have been solved. Results were obtained with...

Description
Summary:Boundary-layer equations with boundary conditions corresponding to a wide range of plane, two-dimensional flows, including the 14 mandatory test cases of the 1968 AFOSR-IFD-Stanford Conference and those over the sub-and supercritical airfoils of Nakayama, have been solved. Results were obtained with turbulence models based on an algebraic eddy-viscosity formula, the equations for turbulent kinetic energy and dissipation rate, and equations for the Reynolds stresses and dissipation rate. They are shown to depend upon the model in an almost random manner. The cost penalty associated with the higher order model is quantified and it is concluded that, for the flows considered, a well-founded algebraic eddy- viscosity model is preferred. (Author)
