hello,
I'm gonna model a cylindrical hollow fiber
( a hollow cylinder with porous walls ,Diameter=100 micrometer , pore size=0.5 micrometer)
with water-gas mixture flowing into it's lumen ,and see the amount of oxygen passing through pores due to Diffusion and mass transfer .
I define the wall as porous jump (in fluent) but don't know how to import the mixture and solve navier stocks and mass transfer equations!

please help me out!
1. which solver should I choose, fluent or CFX?
2.how to define this mixture of water and oxygen and see concentration profiles?
thank you.
