simulate wetting and film evaporation with openfoam

katy · September 12, 2013, 11:41

Hello,

I would like to simulate the wetting and drying process of complicated rigid geometries. Therefore I am wondering which solver is the best to model those effects.

It should handle:
thin films
capillary forces
mass transfer between 2 phases
diffusion

Maybe I will have to combine some solvers...

Can anyone give me a hint?
Thanks a lot!

i guess you should write your own solver
but interFoam or interPhaseChangeFoam can be considered as basic solver for you
but you need to add energy equation and some sub model to resolve thin film model

Thank you for the fast reply! I do not think that I am able to write my own solver. I was hoping, that it was possible to combine some solvers as
-dieselSpray
-reactingParcelFilmFoam
-interPhaseChangeFoam
-...
but I am not sure if one of those includes capillary forces.

atleast, i know interPhaseChangeFoam considers surface tension
