Fluent multiphase

sm.ensmp · March 3, 2010, 08:18

Hi,
I am modelling an a microchannel evaporator. I know that i have two phases but i dont know the flow pattern if it is bubbly flow or droplet flow.
So based on an article i chose the air as the primary phase and the water as the secondary one.
I tried the opposite case and i had different resultats.
I used the eulerian model per phase, K-E standard.
Can u help me to know on which bases we choose the primary and the secondary phase.

Thank you

By the title of your post, it seems you might be in the wrong forum?

I'm guessing you'll get more useful help in the Fluent forum for a Fluent-oriented question. If, instead, you are modeling with FLOW-3D, you should say so.
