Five popular turbulence models have been tested and validated against experimental data of two turbulent flows.The models are:(1)the zero equation model of Baldwin Lomax;(2)the two equation k ε model of Jones and Launder;(3)the two equation k ω model of Wilcox;(4)the two equation k ω/k ε SST model of Menter;(5)the two scale k ε model.The benchmark flows are two transonic flows over bump geometries with shock wave/boundary layer interaction including separation.The computational results demonstrate that the SST model yields superior performance and the zero equation turbulence model does not provide satisfactory results.
