 April 9, 2009, 21:56 Volume Fraction in VOF model #1 Senior Member   Saima Join Date: Apr 2009 Location: Canada Posts: 185 Rep Power: 9 Hi all, I have 2phase problem with water and air. The primary phase is air and secondary phase is water. I know the liquid water content which is 0.84 gm/m3 . Now i am not able to figure out what should be the volume fraction of water. Kindly help me. Thanks in advance Regards, Saima

Hope this helps.
