Dear. Foamers.

Hi..

I am trying to use k-w SST SAS with rhoCentralFoam for compressible flows.
But, I did not find out any example file for set-up.
I will appreciate it if someone has an example file using SAS and share it with me.

Thanks

Hi eddykendo

I might be wrong but kOmegaSSTSAS is an incompressible model. Here the information from the source code:

kOmegaSSTSAS LES turbulence model for incompressible flows based on:
"Evaluation of the SST-SAS model: channel flow, asymmetric diffuser and axi-symmetric hill". European Conference on Computational Fluid Dynamics ECCOMAS CFD 2006. Lars Davidson
The first term of the Qsas expression is corrected following:
DESider A European Effort on Hybrid RANS-LES Modelling: Results of the European-Union Funded Project, 2004 - 2007 (Notes on Numerical Fluid Mechanics and Multidisciplinary Design). Chapter 2, section 8 Formulation of the Scale-Adaptive Simulation (SAS) Model during the DESIDER Project. Published in Springer-Verlag Berlin Heidelberg 2009. F. R. Menter and Y. Egorov.

Cheers

Fabian

Hi

Have you managed to find any tutorials on the OpenFoam SAS model?


Thanks,

Tom
