Default Two phase flow with VOF
Posts: n/a
I am working on annular flow modelling with VOF model. VOF model is very unstable to capture annular flow's details. Interface position is important for me but I could find any satisfactory solution. How can I can get better solutions with Fluent's VOF model? Is someone there who can help me to provide information for this problem? Thanks already

Maybe you need to try unsteady simulation. I solve VOF with tiny time step before and found the result satisfactory. Maybe you also need to apply 2nd order discretisation too. regards, Jolius
