Abstract

This paper describes the results of applications of one equation WrayAgarwal (WA) turbulence model in computing the flow over two 3D NASA benchmark problems: flow over a hemisphere-cylinder and a modified 3D bump in channel flow. The results obtained with the Wray-Agarwal turbulence model are compared to Spalart-Allmaras (SA) turbulence model. Computations for hemisphere-cylinder flow were performed at several angles of attack and compared with experimental data. Computations for the 3D bump in channel flow were compared to the highly refined results from NASA Turbulence Modelling Resource website. For both cases, it is shown that the Wray-Agarwal model has better accuracy compared to the Spalart-Allmaras model.
