Context : I am trying to finalize the implementation of evaporations models in VoF for OpenFOAM 12/13. So I saw that "compressibleCavitation" and incompressibleCavitation models both use the constantPressure files. Analogically I wanted to add the evaporation/condensation model using the constantTemperature files. Question : Physically speaking, when I use cavitation or evaporation/condensation respectively, I observe a mass transfer depending on the pressure gradient for a given temperature (constant) and temperature gradient for a given pressure (constant). Thus, why is the "saturationPressure" (for cavitation) uses "constantPressure" titled files and "saturationTemperature" (for evaporation/condensation) uses "constantTemperature" titled files ?
