Dear all,

Does anybody know how to enable the curvature correction in the k Omega SST model? I am using OpenFOAM 2.1. Thank you

best regards
Luca

I'm not aware of any rotation or curvature sensitized kOmegaSST in OpenFOAM.
Very glad to discover I'm wrong
Can you please provide more details on what you actually mean?

I am investigating a flow that is characterised by highly curved streamlines. The k-Omega SST is based on the Boussinesq appox then the Re stress tensor is forced to be aligned to the mean strain rate tensor. I have tried to use a RSTM turbulence model as it solves directly the Re stress tensor (then it avoids this problem) but it much more computational expensive. For this reason I would like to use a curvature correction in a 2-eq model. This correction term is described in this paper: " Shur, M. L., Strelets, M. K., Travin, A. K., Spalart, P. R., "Turbulence Modeling in Rotating and Curved Channels: Assessing the Spalart-Shur Correction," AIAA Journal Vol. 38, No. 5, 2000, pp. 784-792."

Surfing internet I have found out that someone has already developed a modified k-Omega SST library with the curvature correction term:

Hi LM4112,

"https://github.com/Unsupported-Contr...x/pull/7/files (however now it seems that the website is down)". What u mean?

I tried the website and works fine. I guess you can find the code that you are looking for there.

Regards,

Now it is working, yesterday when I wrote the post it wasn't .

hi Luca,

have you tried the kOmegaSST with rotation correction? How was it?
