Mutliphase Flows, Virtual mass, Bubbly flows

KP;

Hi CFD champs,

I am working on modelling of bubbly flows. During the course of simulations lot of numerical instabilities leading to numerical divergence is observed when virtual mass is included in case set up. It would be interesting and helpful for me if some one can share their experience in the context of virtual mass. Just to give more insight to the situation I use FLUENT and Eulerian-Eulerian method for solving governing equations. Thanks for help in advance. Eagerly waiting for replies!
