Continuse Phase in Two Phase Flow

ali_kntu · February 4, 2014, 02:52

hi
i want to model two phase flow (water - vapor) with high vapor void fraction about 0.9 (alpha=0.9). i don't know in such analysis with high vapor volume fraction, vapor should be continuous phase or dispersed phase?

You have to consider the fluid. Is it best to think of it as mainly vapour with some water, or water with some vapour? In your case it sounds like vapour with some water makes sense. So I would try vapour as the continuous phase. But if it causes problems try it with water as the continuous phase.

Thanks for your attention
