Default Multiphase problem
Posts: n/a
Hi I am working with CFX 5.5 I would like to solve a problem where a gas is resolved in water. But at interface between water and air, the gas is diffuses into the air.

I can calculate the mass flux in 1d using the Fick law. But since the diffusion is very much dependent on the air change rate (the change in local pressure at the interface) I would like to calculate the mass flux in 3d at the interface.

Are there any one who can give me some advise on how to setup such a case ?
