Default Question on turbulent dispersion force in momentum

Hi everyone, I'm simulating a stirred tank with one dispersed bubble phase (Eulerian - k-eps dispersed model). I'd like to know if the turbulent dispersion force by Simonin (accessed through the TUI) is significant in this kind of flow. I tend to think it is. The thing is it is difficult to get convergence in this configuration with the turbulent dispersion force. Is it due to the free surface flow interface between primary and secondary phase ? Does anyone have a strategy or a clue about this ? I keep digging. Cheers Emm.
