Hi Formers
I have managed to implement the interPhaseChangeFoam solver according to the project done by Martin Andersen,So i have a solver that Psat depend temprature.now,I want use this solver for my case,But I dont know how modified empirical coefficients in mass transfer models.foe example if I choose Kunz model ,How determine t or Cprod or Cdest ?
If in my case,dont have velocity (all of the case U=0)? whats happen?
It means,I have a case with water and vapor and I want evaporate water with Temprature (Psat depend temp)...
regards,
Nazanin

Hi Nazanin
for stimulation evaporate with temp,I think you should use another mass transfer model and modified the source term
you can read this page
http://www.cfd-online.com/Forums/blo...-openfoam.html

or if you use this solver I think you should variable diffusion coefficient [DT ] based on the volume fraction of both phases.I did this work,but I have problem too. you tell good point...can we use interPhasechangeFoam solver base this phasechange model without U. as I know ,this solver for cavitation and Cavitation without U....?
you can see my thread in this page:
