摘要

The Scale-Adaptive Simulation (SAS) based on SST turbulence model is more and more popular as a new hybrid RANS/LES method. The flow around AS239 airfoil at the maximum lift condition is simulated by SST-SAS to test its behavior in the mild separation. Compared with results from SST-DES and SST-DDES, SST-SAS on one hand overcomes the Grid Induced Separation (GIS) near the boundary like the delay of RANS in SST-DDES and on the other hand, it decreases the grey area in the wake and gets clearer vortexes and more accurate velocity profile than those obtainable with SST-DDES.
