K-e model and tip clearance
I get a very good convergence using SA turbulent model. But when I use the three low Re K-e model to compute the same case, I can't get a good convergence. And the same problem is met when I add a tip clearance on the rotor using SA model.
I try many methods such as regenerate the grid to get a good quality.
My project is a three stages turbine.
Who meet the same problem and how to resolve it?
Thanks very much.
