Hi, Foamers
I have been using Hybrid LES/RANS like DES, DDES only for incompressible flows. At this time, I'd like to use Spalart-Allmara DDES or k-w SST DDES (implemented by me) with rhoCentralFoam in OpenFOAM v2.30. I want to know if I can still use those Hybrid models for compressible solvers without any modifications or additional works. Also, I will appreciate it if anyone has an example file using SAS turbulence model and can share it with me. Thank you. P.S: I remember k-w SST-DDES I implemented was for incompressible flows. By the way, I can still use it for a compressible solver like rhoCentralFoam only by changing "namespace incompressible" into "namespace compressible" in source files and compiling them again? Otherwise, should I modify many portions in source files for compressible solvers? Last edited by eddykendo; July 9, 2015 at 11:13. |

Hi
Which shielding function did you use for the kw-SST DDES? |

Hello,
Could you please share the SST DDES code? I am trying to modify the DDES model in openfoam, but I can't find a ready-made SST-DDES in of5. Besides, do you know something about the definition of 'delta' in DDES? Theoretically, it is a variable about deltax, delaty and deltz, which are sizes of mesh in three directions. However, I can not find the definition code mentioning these three paramenters. Thanks a lot! Anyone who can give me ideas is welcome! Alisa. Quote:

Hello everybodydo
Do you find the sst DDES code, I really need it for my intership I'm looking everywhere but I find the IDDES spalart-allmaras It would be nice of you if someone could share it or tell me what implementation I should do. Gracias |
