[Help] Boundary conditions for turbulent flow (kEpsilon)
Join Date: May 2011

I want to model a turbulent air stream by using kepsilon model. I am pretty new to CFD and therefore stuck defining the right boundary conditions.
According to my virgin openFoam knowledge I do have to define the mesh-boundaries (patch,empty,wall etc) and the initial flow conditions (p,U,(k),(epsilon),(omega),....)
Now my problem: I want to model turbulent air flow in a dump-combustor using kEpsilon model. I do have information about density,viscosity, inlet-speed and turbulence intensity. Do I have to calculate k and epsilon manually in order to define a correct inlet value?
Thanks for reading (and wasting your valuable time ) in advance.
