Abstract
We present an improved Detached Eddy Simulation (DES) based on the SST turbulence model, WAD SST-DES, for accelerating the Large Eddy Simulation (LES) development in mixing layers. Similar to WAD-DES based on the SA turbulence model proposed by Wang and Qin, the formulation of Yoshizawa’s k-equation-like subgrid model in LES zones in the original SST-DES is rewritten as a standard one to end the previous turbulence transfer in the interface between the RANS and LES regions, and the numerical results for flow around A-aerofoil show that these improvements efficiently weaken the influence of the grey area while delaying the RANS at the boundary, in a manner similar to DDES. In addition, we discuss the influence of several coefficients in the improved SST-DES; these coefficients may play a very important role in the final simulation results.
