Hi, I tried to model two round jet but as we know K-Eps model is very weak about this. I found that Pope, Launder and Chung tried to use variable Ceps1 and Ceps2. Is there anybody that applied them in fluent or generated a UDF for solving correct spreading of round jet?

There is some papers about LES of round jet which seems reasonable, but with too much cost.

All suggestions or comments about round jet simulation are mostly welcome.
