Hi, I'm a AVL's FIRE user and I need to know what is the best formulas to obtain the boundary's condition for turbulence (this is simultation for the inlet flow in a Diesel 4 strockes engine). The turbulence model is k-e and the mean speed of flow can vary from 10m/s to 60m/s (experiment's results), so i need the formulas for k, e, and l (lengh scale). I tried to use some formula but it doesn't seem to match. If you have some advise to give me, thanks in advance.
We have an adapted version of the usrbnd.f that allows TKE to be given as a percentage of the mean velocity, which may help you.
I'd be happy to supply this, just contact me and we can arrange a transfer method.
