Dear FOAMers
I'm in the middle of a two phase problem involving bubble growth on plane or coated surfaces.I have already solved the 2d AND 3D problems in FLUENT using a UDF for phase change and VOF for interface tracking but the run time is too long and i have to run it a couple of times for different contact angles and wall superheats so i'm trying to use OpenFOAM for the same problem so i can finish my thesis in time but every 2-phase solver i find only simulates cavitation (no evaporation or boiling).Any suggestion on phase change solvers is appreciated.
PS : The foretold UDF uses an energy source term for 2-phase heat transfer and two source terms for mass transfer for each phase which are equal in magnitude but different in sign.Also there is an extra energy source within the vapor region to ensure that the vapor phase would not exceed the saturation temperature.If anyone needs the UDF i'd be happy to share.
