Dear All,
I need to run a compressible high speed nozzle flow in OF on a low-Re mesh (y+<1). So far I did my calculations with the kOmegaSST turbulence model and it worked quite nice. Now I have to use the k-Epsilon turbulence model on the same mesh. The only low-Re k-epsilon turbulence for a compressible case available in OF is the one by Launder and Sharma. I compared the code of the LaunderSharmaKE with the standard kEpsilon model and found some differences as additional source-terms as well as some turbulent Reynolds-number functions. So I have some questions, hoping anybody can answer these:
Thanks in advance! Sebastian |
