AB In this bachelor’s thesis, the flow over a nominally two-dimensional 20° compressioncorner at M= 2.85 has been simulated in order to evaluate the capabilities of adaptivemesh refinement methods in flows involving shock wave/turbulent boundarylayer interactions. Hence, Reynolds Averaged Navier-Stokes (RANS) simulationshave been carried out using Ansys Fluent to pursue the former objective.The initial grid convergence study using k-omega SST turbulence model showed that theoptimal cell count for a structured mesh in the simulated conditions was 9.0 x 10^4. Inaddition, a turbulence model assessment was performed comparing Spalart-Allmarasmodel with different k-epsilon and k-omega turbulence models. For the studied flow, Georgiadisand Yoder version of the k-omega SST model was the one which showed betteragreement with the experimental values.Finally, different adaptive mesh refinement configurations were tested, regardingpressure and velocity gradients. Thus, results comparable to the fine grid solutionwere obtained, with a reduction of more than an 80% in the overall computationalcost.
