I have a question about a turbulent model in multiphase flows! this is "Lopez de Bertodano" model! is there any instruction for using this model!? is this incompatible with a special settings? such as some boundary condition or some discretization method or something like them? Recounting: I'm working on a bubbly flow. the problem without using "lopez" model is very stable. but when I use this model the problem suddenly been unstable and in a few iterations lead to divergence! Thanks in advance
