Abstract
The objective of this study is to investigate the Detached Eddy Simulation (DES) modifications to the hybrid k , k ! (kk! ) turbulence model and the Scale Adaptive Simulation (SAS) modifications to the one-equation k (1k ) turbulence model. Additionally, modifications to the damping functions to the baseline 1k model are presented and validated for a variety of test cases. Further, the Stress-! (S!) Reynolds stress model is tested alongside the 1k and kk! models. A blended dissipation equation is implemented into the S! model and validated for a variety of test cases. A surface-mounted cube is chosen as the primary test case to examine specifically the highly separated wake flow. Multiple grid levels are used to identify the grid requirements necessary for accurate computations with the kk! DES and 1k SAS models.
