Hello fellow Foamers
I'm new to the Field of CFD and writting my Bachelor Thesis about a mesh analysis in OpenFoam (VOF;InterDyMFoam). (yes i learned it is a long way, notheless a fun one ) So in a meeting with my supervisior we stumbeld over a simple (or not) question. Where is the phaseline between water and air in a VOF simulation? So while in the real world the phase transition of water and air is quite visible, in a VOF simulation it isn't. Mostly because the Voluminas which contain the data are calculated with a ratio of Air and Water in it. What kind of ratio would you use for the phase transition? Well now i've written 2 questions which are kinda related maybe even the same. Feel free to comment/discuss. My answers for the questsions would be: In a real world we see the watersurface so this line constist of 100% (ok 95%) water. Which then results in a ratio of 0.95 to 0.05 (water:air). Thanks for your comments and inputs! Happy Day to you. Alwinder (First Post YAY ) |
