about multiphase
 
when pushing a blanket bottle into water, some bubbles will bubble out of the bottle mouth. How to simulate the progress by using Fluent.

how about using VOF. it may work for your case, but the Vof model cannot account for the compressibility of the air phase.i dont know if this approximation have fluence on the result.

Maybe you can try to use Multiphase Model or Eulerian Model.

I build a model using VOF. The bubble does not rise during the simulation. it always stay near the bottle mouth. Why? I have set the gravity in the model.
