v2-f turbulence model boundary conditions
I've been working with the some v2-f turbulence models in FLUENT (they're user-defined, because my team won't spend money on the FLUENT v2-f model.)
I know the boundary conditions for k, epsilon, and v2, at inlets, outlets, and walls. But, I'm having trouble finding appropriate boundary conditions for f. I'm currently using a derivative of 0 at inlets and outlets and a value of 0 at walls, but I don't know if those are correct.
Has anyone worked with the v2-f models enough to know what the f boundary conditions should be?
Thanks in advance!
Correction: I'm using the f formulation by Lein and Kalitzin ("Computations of Transonic Flows with the v2-f turbulence Model"), and the f boundary condition at solid walls is f=0.
But I still don't know the appropriate inlet and outlet boundary conditions. Can anyone help?
