Question regarding Energy Source term
 

Hej,

I am working on a condensation problem. I am using VOF method. I wrote UDF's for source terms accounting for mass and heat transfer. My doubt is When we have heat transfer during condensation , it should remove heat from steam phase and add heat to liquid phase (in condensation). But in VOF we have only one energy equation which is shared between both phases, and the energy source UDF is give to the mixture level thread. How can I make sure that heat is added in liquid phase and removed from gas phase?

I would really appreciate if some one can answer this.

Thanks in advance,

Regards,
