flow rate - diffusion - outlet condition

Please login with a confirmed email address before reporting spam

Hello
I am trying to do a modeling of a chamber filled with Hydrogen (pur hydrogen - one specie)
I have an inlet with a defined flow rate (laminar flow) on one side and then the gas diffuses through the membrane of the chamber (on 2 sides) to other chambers (filled with water) (see attached pictures)
I don t know how to add the outlet condition for the flow as it is diffusion through membrane?
(pressure / laminar outflow / velocity?)
(I am interested in knowing the concentration of the gas in the chamber while it is going in and diffusing through the membrane)
thanks!
