  I have done vof calculation of heptane in microtube. can anyone help me that how Fluent calculate mass flow rate of each phase in flux reports. I want to know formula and can we take this mass flow rate as evaporation rate?

  No. Theres a ist Phase interaction Variable for post processing. Integrate it over the volume.

  Sir thanks for reply. You mean in Reports>Volume integrals>field variable>phase interaction>mass transfer rate and find volume integral on fluid region.
  
  Further my geometry is 2D, so should i go for surface integral or volume integral?

  Volume integral. And yes that is what I meant.
