mass transfer coefficients in bubble column

    • carmendecrescenzo90


      I need to simulate gas mass transfer in a bubble column.  I used Eulerian multiphase model with 2 phases (liquid and gas in two different mixtures with O2 as common component). I would like to simulate mass  transfer by using species mass transfer but I have problem to identify "To phase- from phase" in Interphase mass transfer coefficient panel (see attached figure). I have just read in Ansyshelp and I found "As in all interphase mass transfer models in Fluent, if a gas mixture is involved in an interphase species mass transfer process, it is always treated as a “to”-phase and the liquid mixture as a “from”-phase." Can someone clarify this sentence?

      Thnak you in advance
