An examination of turbulence models for a separating threedimensional turbulent boundary layer
Abstract
Turbulence modeling in separating 3D boundary layers using an inverse method is discussed. The ability of models developed for 2D flows to predict the separation of a 3D boundary layer is examined, as is the influence of Rotta's (1977) hypothesis that the cause of the disagreement between calculative and experimental prediction of low speed flows with severe crossflow is an inadequate modeling of the pressurestrain correlation term of the Reynolds tensor transport equation. The validity of the considered models is tested by comparison with the wellknown experiments of Van den Berg (1972) and Elsenaar (1974), which simulate an infinite swept wing situation. The boundary layer equations are solved by an inverse method with prescribed displacement thicknesses.
