Shadow phase
 

Hi all

I am working with two-phase flow (liquid and gas). The system is simple vessel just like simple cup full with the liquid phase with open top surface, and the gas is injected from the bottom through a porous media. The point is that the gas bubbles diameter varies during its journey to the top surface. There is a technique called "Shadow phase" or so used to predict the bubbles diameters variation. However, I wonder if Fluent 6 does support such a technique or on the other hand how does Fluent calculate the gas bubbles size variation.

ManyThanks
