Hello to everyone,
I would like to ask for any suggestions regarding which turbulence model to use for an incompressible internal flow. My grid is coarse and as far as i know the k-w model requires very fine grids. I would appreciate any suggestions on that.

Kindest Regards

As first approximation try standard turbulent models with reference to Fluent UG. There is a good guide that tells you which model is suitable depending on your problem, Re and flow type...

K-epsilon model is generally recommended for internal flows and k-epsilon model can handle course meshes having wall y+ 30-300
