The shock wave turbulent boundary layer interaction (STBLI) phenomenon has been actively researched in the last five decades. These interactions usually occur in hypersonic vehicles, where the shock generated from control surfaces interacts with the attached boundary layer. Designing hypersonic vehicles requires a tool to predict the aerothermodynamic loads, which can be done by performing Computation Fluid Dynamics (CFD) simulations. Reynolds-Averaged Navier-Stokes (RANS) simulations have been extensively used to predict the turbulent flow behavior, which utilizes the turbulence model to solve the nonlinear RANS equations. This computational study comprises two-dimensional RANS simulations of the interaction of incident shock waves with a turbulent boundary layer at Mach 6 in the presence of surface blowing. A couple of cases were computed, one without the surface blowing and the other with the presence of surface blowing. The computed results of surface heat transfer and pressure are compared with the experimental study done at the Calspan University at Buffalo Research Center (CUBRC). For this thesis, the k − ω and k − ϵ turbulence models were utilized to predict the surface heat transfer and pressure. The results show that both models predict the peak pressure values with experimental uncertainty in both cases. The k − ϵ model predicts the peak heat transfer with reasonable error in both cases. The k − ω model underpredicted the peak heat transfer in the case without surface blowing and gave anomalous results in predicting surface heat transfer over a porous plate. However, both turbulence models have proven to be poor predictors in the STBLI region.
