Abstract

Accurate turbulence modeling remains a critical problem in the prediction capability of computational fluid dynamics. One particular flow regime lacking accurate simulation is instances of separated flow. In this paper the Rahman-Agarwal-Siikonen (RAS) model is used to simulate the flow of several canonical separated flow cases. The commercially available software ANSYS FLUENT and the open source software OpenFOAM are used for the flow calculations. It is shown that the RAS model significantly increases the accuracy of flow simulations compared to the commonly used Spalart-Allmaras (SA) and Shear-Stress-Transport (SST) k-ω models.
