In this study, the performance of the Wray-Agarwal one-equation turbulence model is evaluated using Shock Wave-Boundary Layer Interaction (SWBLI) test cases. Also, a recently tested formulation by Raje and Sinha aiming for enhancement in SWBLI flow predictions for the k-ω SST model is applied to the Wray-Agarwal turbulence model as an extension. By introducing Reynolds stress anisotropy to the turbulent boundary layer, an updated version of the Wray-Agarwal model is proposed. The modified version of the model is tested using supersonic and hypersonic compression ramps and impinging shock-type flow problems. It is shown that the current extended version of the model predicts the shock-induced separation locations more accurately than the standard Wray-Agarwal model for compression ramptype flow problems. The modifications have no significant effect on the predictions of impinging shock-type problems.
