This report contains the detailed description of the study of the canonical shock-turbulence interaction (STI) problem performed with the DLR’s TAU CFD solver. STI studies reported in the literature are typically performed with high-order (> 2nd) accurate numerical schemes for space- and time discretizations. Instead, TAU, being a code used for both industrial and academic purposes, contains second-order accurate numerics. The motivation of this work is to understand how such a solver copes with the canonical STI setup which requires low dissipation to describe the turbulence accurately while higher dissipation is needed to avoid numerical issues in the shock capturing process. To this end, the scale-resolving capability of TAU has been carefully investigated for several STI’s where turbulence has been described with a Large Eddy Simulations (LES) method
