A three-dimensional oblique shock/turbulent boundary-layer interaction is computed using a hybrid explicitimplicit numerical algorithm for the compressible Navier-Stokes equations. The flow configuration consists of a sharp fin or wedge, attached normal to a flat plate. The deflection of the wedge generates an oblique shock wave that interacts with the turbulent boundary layer on the flat plate. Computed results are obtained at Mach number M = 3 for a wedge angle of 10 deg and Reynolds number of Reδ∞ = 2.8 × 105 based on the undisturbed boundary-layer thickness δ upstream of the sharp fin. These results, together with the results of a previous computation for the same configuration at Reδ∞ = 9.3 × 105, are compared to the recent experimental data of McClure and Dolling. The computed results are in generally good agreement with the experiment and predict with reasonable accuracy the recovery of the boundary layer to a nominal two-dimensional state downstream of the interaction. Contour plots of various flow variables are employed to investigate the flow structure for the Reδ∞ = 2.8 × 105 case and to compare with the model developed by Oskam, et al. based upon experimental measurements at Reδ∞= 9.3 × 105.
