Grid Refinement for Round Jet
 
Hello,

I try to do some simple steady state simulations of round free jets (Mach < 0.3, Re about 7000-8000). I'm using the k-e model and it's extensions. The problem is that when I refine the grid, to a certain point, the Jet plume shrinks so it doesn't even leave the domain (it should).

So my question is; Is there a minimum cell size connected with the transport of k and e?

Best Regards

M

Sorry for spamming the thread, but I found the answer. It was simply a matter of convergence criterion.

The question about the smallest recommended grid size for the k-e model is still interresting however.

Cheers!
