Two phase flow of air and water with two inlet
 

I am Trying to simulate the wellbore model in Ansys Fluent.
It is a two phase model with water and air.
The ultimate result could be a slug flow
Which model and what settings should I use in Fluent to simulate this model?
Please help

Is there anyone who can help me?

multiphase is the word?
set up one multiphase domain. One inlet is water only, the other is the mixture. Then outlet as mass flow.
Guess you need to apply buoyancy as well.
so there is your 2 words: multiphase and buoyancy, lots of stuff in the web with and without pictures.

You have to enable multi phase in model
add water in material (default of material is air so after that you got 2 material)
change the material in phase 1 to air and phase 2 to water in Phase
Set the inlet 1 and inlet 2 with the phase you chose
I don't know exactly how to setup outlet but mass flow is the good advise so try it, why not

Thanks everyone, I am trying the suggestions.

Besides I will appreciate if people still continue to comment. I will post the results once i obtain it.

try massflow both inlets and outlets.
The pressure will be ok then. I got weird flows otherwise, if I define mass in and 0 pressure out, I get very different mass flows at the outlets.
