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 http://s3.picofile.com/file/82204120...sentation1.jpg Pressure http://s3.picofile.com/file/82204122...sentation2.jpg Temperature http://s3.picofile.com/file/82204125...sentation3.jpg velocity http://s3.picofile.com/file/82204126...sentation4.jpg |

I am working with two dimensional film boiling too. I am getting so much trouble constructing the interface given by the following equation:
filmeqn.PNG And the figure came out like this: film2D.png Why I am not getting the correct interface? Any idea should be appreciated. |
