Urgent help please: Oxygen transfer between phase
 
Hello everybody,

Oxygen bubbles are transported by water in a pipe. Some of oxygen is dissolved into water. Of course gas-liquid two-phase flow model will be used. But how to treat the oxygen transfer between the two phases? Thanks a lot in advance!

You could have a two-phase flow, with the water being made of a multicomponent thread water-air. You must then write a governing equation for the phase exchange (source/sink in cel for example)feeding the water component of the fluid phase... I am sure than you can speak to the CFX support engineer for questions of implementation.
