InterFoam : Calculate heat/concentration flux at the interface

Vietazz · May 21, 2016, 17:02

Hello everyone,

I am using interFoam to simulate mass transfer from a rising droplet in a quiscent immiscible liquid.
I succeeded to implement the concentration equation in the interfoam solver

! Resulats are pretty good !
Nom I'd like to post-process the integral of the concentration flux around the interface so I can calculate the Sherwood numbder (the equivalent of the Nusselt number in thermal problem) . I searched for a solution evreywhere without a result !!
I'll be really grateful to whoever may suggest a piece of help

Sincerly,

I am really stuck ! can anybody help plz ..?
Here is what I wanna do :
I am trying to calculate the integrale of D.\nabla (C)*n over the region where alpha=1.
C : concentration
D : diffucivity
n : normal unit vector to the interface
* : inner product

I will appreciate any help ...

My project also involves similar work. can you please share your concentration equation code with me.

Hey guys !

Did you manage to implement this concentration equation in interFoam ? If yes, would you mind share the code or the process ? I am stuck with the same problem.

Sincerely,
Santhosh
