Problem is considered 2D.

How can I define an oversaturated water flow (oversaturated with oxygen in my case)<br \/>2. Is Fluent solver able to solve the concentration differential equation and determine the mass transfer which leads to growth of the gas bubble<br \/>3. I am thinking of using VOF model to capture the change of the interface. Any thoughts about this?<br \/>4. How to inject the bubble from a site?<br \/>5.
