Hi fiends,

I implement Lee mass transfer model in openFoam (interPhaseChangeFoam)

and in first step I validate it by 1D stefan problem.But in 2D film boiling case

solver doesn't work correctly and mushroom shape doesn't appear and

interface going up and finally give linear shape!!!

in my case Sp=-vDotAlphal and Su=divU*alpha1

and pressure source term is +vDotp.

I put some photos of pressure + temperature and volume fraction in

different times :

Alpha or volume fraction

I am working with two dimensional film boiling too. I am getting so much trouble constructing the interface given by the following equation:

And the figure came out like this:

Why I am not getting the correct interface? Any idea should be appreciated.

Are you using Symmetry? if yes, then change reflect plane
