Questions about model constant of Cmu in Fluent
 
Hi, I am doing sensitivity study on model constant of Cmu. We know that Cmu is ralated to the turbulent visicosity. Given the fixed inlet condition of mean veloctiy and K and E, with the increasing of the Cmu, the turbulent visicosity become larger. The question is how the larger turbulent visicosity affect the computation result, more specifically, affect the computation result of k in the domain? Many thank!
