A New Low Reynolds Number One-Equation Turbulence Model Based on a k-k-ω Closure

46th AIAA Fluid Dynamics Conference (2014)

Tim Wray Ramesh K. Agarwal

Accurate turbulence modeling remains a critical problem in the prediction capability of computational fluid dynamics. In this paper a new one equation eddy viscosity model is derived from k-ω closure. The ω-equation used in this derivation includes a cross diffusion term that allows the new model to switch between a k-ω or k-e behavior. The new model is used to simulate the flow of several canonical separated flow cases. The open source software OpenFOAM is used for the flow calculations. It is shown that the new model increases the accuracy of flow simulations compared to the commonly used Spalart-Allmaras (SA) and Shear-Stress-Transport (SST) k-ω models for several of these flows.
