modelling bubble dynamics
Hi guys,

I am trying to model a bubble in a channel. I am trying to solve it in a 2D axisymmetric way. I have problems in meshing. What kind of mesh should i use? Sliding mesh or Dynamic mesh. I am using a constant velocity at the inlet will the wall being stationary. Do i need to change it with a moving wall boundary condition? I want the bubble to move with the flow.

Hi Arun,

You don't need to create two different mesh for water and vapor. Mesh has to be a single in domain. Thing is you have to define all those data of bubble in multiphase model.
