Two-fluid models vs mixture models for bubbly flows

Hansong Tang

Maybe you are a specialist in two-phase problems and know which model, two-fluid model and mixture model, is better for bubbly flows. It seems that many people use two-fluid models, especially for engineering problems. But this kind of models has drawbacks, e.g., it needs two sets of governing equations, one for gas and the other for water, and thus is too complicated. On the other hand, mixture models seem to be less complicated, but I have not found some papers about their turbulence models. If you know something about this, please let me know. Thanks a lot.
