Does anyone know if OpenFoam has an implementation of David Wilcox's latest k-omega turbulence model? I am specifically referring to the one referenced in:

"Formulation of the k-omega Turbulence Model Revisited"
David Wilcox
AIAA Journal Nov. 2008

I have found his older model (kOmega)...

Thanks in advance.

The implementation of the kOmega in OpenFOAM is from 1988, it is already different from the 2006 version (Wilcox, Turbulence Modeling for CFD, 3rd Edition,2006).

It should not be too hard to change the equation and recompile the model with. The version from 2006 for example is missing the stress delimiter and the cross diffusion term. Both of them are fairly easily added to the equations already in place under $FOAM_SRC/turbulenceModels/incompressible/RAS/kOmega. You would need some C++ knowledge though in order to modify the model.
