Evaluation of anisotropic turbulence models for the calculation of plane-of-symmetry boundary layers
Abstract
Three versions of the anisotropic k-epsilon turbulence model are compared to calculate the plane of symmetry boundary layer which include an algebraic stress model (Rodi, 1984), a nonlinear k-epsilon model (Speziale, 1987), and an anisotropic model (Nisizima and Yoshizawa, 1987). Results indicate that the anisotropic turbulence model performs most satisfactorily for the boundary-layer calculation in the plane of symmetry of a body of revolution. The algebraic stress model and the nonlinear k-epsilon model yield improved results over the standard k-epsilon model and the integral parameters are well predicted.
