Abstract
The aim of this work is to assess the numerical requirements, computational cost and prediction capabilities of two Hybrid formulations, Scale Adaptive Simulation (SAS)and Delayed Detached Eddy Simulation (DDES), and of the Partially-Averaged Navier Stokes (PANS) equations PANS based on an adapted k-omega SST model. The selected test case is the fow over a backwardfacing step at a Reynolds number based on the step height h of 37500.
