Abstract: The tool of choice in computing turbulent flows of engineering interest is the Reynolds averaged Navier-Stokes equations for the mean motion, coupled with a closure scheme for the unknown higher-order turbulent correlations. The focus of this paper is to discuss some recent advances in turbulent closure schemes and their application to a weakly compressible flow. Specifically highlighted are the development and utilization of formulations for obtaining explicit algebraic stress and dissipation rate models. Results are presented for the flow over a two-dimensional single element airfoil as well as the downstream wake flow using the explicit algebraic stress model with a comparison to both experiment and a standard isotropic eddy viscosity model.
