Does anybody have a (good) description for the RAS model? I found a lot about the LES and RANS modells on the internet, but unfortunately nothimg about the RAS model!
Regards, Ilja |

Hi,Ilja
From my understanding, LES (Large eddy simulation) and RANS (Reynolds Averaged Numerical Simulation) are different approaches or methodologies to handle the turbulence problems. RAS (Reynolds Averaged Stress) models are based on RANS. I am not quite sure whether I am completely right. Regards Jinbiao |

I mean if you can understand RANS, then it will be easy for you to understand RAS models. Sometimes RAS is used instead of RANS though. There are many RAS models. I am sorry that I do not have a good paper about them.
I think the following webpage may be helpful http://www.cfd-online.com/Wiki/Reyno...ess_model_(RSM) |
