Default Multi-phase Modelling

Posts: n/a
Hello all:

I am using CFX 5.6. My experience with CFX is low. My experience with CFD is low.

I wish to set up a model that simulates two-phase flow in a vertical pipe. Essentially, I am modelling taylor bubbles. Of special concern is the entrainment area at the bottom of the bubble, however I would be glad to get the general shape modelled to get started.

I would like to get some advice on how to get a model set up and initiated properly to get bubble formation.

I would also like to know generally what kind of mesh would be best and what kind of solution times I can expect.

As I see it, I have two general options for the model. Homgeneous and Inhomogeneous. Initially, I am using the homogeneous model with free surfaces. I would like to get some reasonable results with this before attempting a nonhomogeneous model.

Any advice would be appreciated.

Any takers? All I am really looking for are some general guidelines for modelling gas bubbles.

My setup is as follows:

Vertical Pipe, 50 mm diameter, 5 m length. Stagnant water to start.
