Abstract
In the present paper a Delayed Detached-Eddy Simulation (DDES) based on the strain-adaptive linear Spalart-Allmaras (SALSA) model is performed in order to investigate the transonic flow over the OAT15A supercritical airfoil within the buffet regime. The results are compared with 2D and 3D-URANS computations using the SALSA model, as well as with experimental data. This study shows improvements achieved in the prediction of the flow unsteadiness and statistics by means of the DDES.
