Dear All members,

In my problem (laminar flow in permeable tube) I must solve navier-stokes and mass transfer equation together. But I have problem in this coupling. I think because mass transfer equation is slower than momentum equation, my answers are not reliable. velocity changes very fast but concentration changes very slowly ...

Any comments will be greatly appreciated. Thank you.

Hi , I just start learning CFX. Could I ask how do you know you solve N-S equation in CFX? or Reynolds equation? Can we know it from CFX software?
