Hi Foamers,

I am trying to estimate heat transfer over vertical surfaces using twoPhaseEulerFoam. I have got the variation of thermal n velocity profile as required bt the problem is there isnt any variation for alpha as the process is condensation. I tried to make several changes in equation sets and formulations bt nthng is seems to be working... any suggestions?

Hi,

Did you manage to sort it out?
I think, you should put some small number for alpha1 because condensation depends on alpha1, if you check the code, you can see it...
what is the geometry are you using? and p_rgh BC?
