摘要：
The purpose of this article is to compare various CFD approaches for modeling turbulent flows, specifically the two-equation Reynolds-averaged Navier-Stokes (RANS) Menter's Shear Stress Transport turbulence model (SST) and its various hybrids with large eddy simulation (LES): detached-eddy simulation (DES), delayed DES (DDES) and improved delayed DES (IDDES). We compare these RANS and hybrid RANS-LES methods on a diffuser problem with experimental data.
