How can I add a vapor fraction in the chtMultiRegionFoam?
Is for implementing a phase change simulation using that solver. |

In the ESI development line of OpenFOAM (openfoam.com) there is the solver chtMultiRegionTwoPhaseEulerFoam which can do what you want. See https://www.openfoam.com/releases/op...nd-physics.php

There are two "challenges":
The first one is to get a new solver based on chtMultiRegionFoam. There you have to replace the solver in the fluid folder with your base solve (interCondensatingEvaporatingFoam). This is just "programming", but a a lot. The second one is you have to find new boundary conditions for the wall where you model what happens physically there. Boiling/condensation? Then you have to implement it. If you look at the solver of ESI and the corresponding wall modelling, you can see, this is even more work. How much time do you have? Do you have help by co-workers? This sounds more like a at least one PhD thesis than e. g. a master thesis. |
