Battousai07 is on a distinguished road
Hello All,
As a part of a research project, i am trying to create a a openfoam solver which solves cavitation for different phases. After some literature survey i decided to use 2 phase ( liquid and vapor) and 4 species. The liquid phase should be consisted of 2 species, and vapor phase also need to be consisted of 2 species that are the vapor forms of the species in liquid phase. The idea here is to drive the cavitation through the species. (A.liquid ==> A.gas, and B.liquid ==> B.gas). I decided to choose reactingTwoPhaseEulerFoam since it already supports the multiComponentPhases and even the phase change between phases. The twoPhaseSystem class controls the mass transfer between phases. Selecting "thermalPhaseChangeTwoPhaseSystem" mass transfer is drived by the temperature gradient. I am trying to create twoPhaseSystem where the mass transfer is drived by a certain pressure condition. My question is, as far as i understood, the phase change only occurs at the interface in this solver. Would it be also possible to create new interfaces at the locations where pressure drops below under saturation pressure? I could not be sure whether this solver already can handle creating new interfaces or not.
Thanks in advance
