3D 2-phase flow simulation (gas/liquid)
3D 2-phase flow simulation (gas/liquid)
Hi, been a while since I've been on here or involved with any CFD. My company is wanting me to try to find an open-source package that can simulate 2 or even 3-phase fluid flow. I've done simple single-phase flow simulations using Code_Saturne before and am pretty familiar with it, but I've been wanting to start using Elmer as it seems like a more powerful package. My question is, can this be done in Elmer, and will it require custom Fortran? Really don't even know where to start. Would appreciate a nudge in the right direction, or even a suggestion for a different CFD package that might be able to accommodate me better. I'm pretty handy with SALOME so I can get the mesh made and post-process the results and whatnot, just don't know which open-source packages, if any, can do this out of the box or with little modification. Thanks in advance.

Hi,
I am not a CFD expert, but a quick search in the forum reveals that in principle fluid flows with more than one phase can be simulated with Elmer, see the following posts:

That said, you should also have a look at OpenFoam which is certainly more specialized on CFD.
More specific CFD questions will have to be answered by someone else...
HTH,
Matthias

To get started with Elmer, you can have a look at the tutorials. The solvers are described in the Models manual.
Elmer can import the mesh in unv format as exported by Salomé.
