abstract = {In this bachelor’s thesis, the flow over a nominally two-dimensional 20° compression
corner at M= 2.85 has been simulated in order to evaluate the capabilities of adaptive
mesh refinement methods in flows involving shock wave/turbulent boundary
layer interactions. Hence, Reynolds Averaged Navier-Stokes (RANS) simulations
have been carried out using Ansys Fluent to pursue the former objective.

The initial grid convergence study using k-omega SST turbulence model showed that the
optimal cell count for a structured mesh in the simulated conditions was 9.0 x 10^4. In
addition, a turbulence model assessment was performed comparing Spalart-Allmaras
model with different k-epsilon and k-omega turbulence models. For the studied flow, Georgiadis
and Yoder version of the k-omega SST model was the one which showed better
agreement with the experimental values.

Finally, different adaptive mesh refinement configurations were tested, regarding
pressure and velocity gradients. Thus, results comparable to the fine grid solution
were obtained, with a reduction of more than an 80% in the overall computational
cost.},
