Diffusion
 

Hi Friends

I need to do CFD analysis on simple diffusion problem. Geometry is cylindrical having two inlet and one outlet. From one inlet "Helium" gas is going in and from other "Nitrogen gas". They both get mixed inside the pipe and come out form the outlet. There is no reaction involve in the process. I need to see how well the mixing happen inside the pipe

The problem is i have not performed and species transport simulation or diffusion related problem. I was looking for starting point here.

It would be great help if there is any tutorial which solves the basic diffusion problem. The tutorial i found "Surface Chemistry" and all have reaction involve.

Thanks for any help

Hey guy
It's easy and straightforward. You need to define a UDS and then define your diffusivity coefficients properly. Contact me, I can tell you even more. But now I'm a little busy.
Good luck
