Three-dimensional swept shock wave/turbulent boundary layer interaction and its control by means of bleed are important subjects in supersonic air intake development. In the present study, the modeled flowfield is computed using an explicit numerical algorithm for the compressible Navier-Stokes equations. The results are obtained at free-stream Mach numbers of 3.25 and 3.11 employing zero and two equation turbulence models with and without boundary layer bleed around the interaction region. The results with two equation model show less agreement with the experimental data than those with zero equation model because of the overprediction for eddy viscosity. We confirm that the latter code is available for a tool to design a supersonic intake with bleed. Also, this study provides important information about the flowfield and reproducibility of bleed effect. For more accurate prediction, however, new modelling for bleed boundary conditions should be introduced.
