Hello

I am new to openFoam and I am trying to run 2D case with flow over a cylinder using the K-omega model. In the tutorial I found online they are setting up the cylinder like this (see picture). What is Cmu, kappa, E and beta1 ? Why not just say that the omegaWallfunctions is uniform? What is the physics behind Cmu, kappa, E and beta1?
