The evaluation will focus on Scale-Adaptive Simulation (SAS) (Menter et al., 2003), which smoothly combines RANS and LES capabilities. The resulting flow fields are discussed along URANS, LES and corresponding measurements. The question arises, if SAS methods may combine advantages of RANS and ...
It is well known that no turbulent model can excellently perform for every application, as well as the SST-SAS model. One objection to the current SST-SAS implementation is that there is no production limiter included, aiming at avoiding the spurious generation of turbulence energy in the stagn...
Hi, I recently implemented the kOmegaSST-SAS model to RAS turbulence model side, so one can use wall functions if desired. It's based on the paper "Development and Application of SST-SAS Turbulence Model in the DESIDER Project" (C) Springer-Verlag Heidelberg 2008 Y. Egorov and F. Ment...
The SAS model (Scale Adapted Simulation) was invented by Menter and his co-workers. The idea behind the SST-SAS model is to add an additional production term - the SAS term - in the w equation which is sensitive to resolved (i.e. unsteady) fluctuations. In regions where the flow is ...
I was running several simulations with the SST Transitional model. Before we updated the license, the transitional model worked fine, but now it seems to have disappeared from Pre along with the SAS model. I am using version 12.1. Has this happened to anyone before? Tech support doesn't ...
