Multiphase flow in a porous-no porous domains
 

Hello everybody,

I an trying to simulate the next situation:

- I have two domains: one ist porous with a gas (air) and the other ist no porous with another gas (water vapour).
- Inside the porous domain, I have an area of particles injection.

I want to know how is the diffusion of these particles in the whole domain /the two domains).

Attached find you the geometry,

please, can somebody help me?

thank you in advance!

This sounds like a single phase model, but using a multi-component gas. You might also be able to do it using a passive transportable scalar. And you have one sub-domain as fluid and one as porous. This sound simple enough.
