Hey Joe,

I haven't done much on this topic lately since I had to work on another problem first. I have been in contact with Holger Marschall though who is developing another solver for the...

Hey Andrew,

no, I have not released any paper yet. Are you interested in the CH solver?

Anil,

the biggest problem will be to find a solver which can handle this kind of complex physics. You need a multiphase solver (> 2 phases) which can handle energy transport and phase change!...

Anil,

you don't need the C-H model for your purpose. The normal VOF model can simulate the agglomeration of the bubbles also.

Hello Anil,

the VOF or EULER methods have a different background. These methods differ in the treatment of the whole multiphase system. The VOF method uses an additional equation (alpha = phase...

After initializing with a maximum alpha1 of 0.55 it decreases to 0.5 during the first time steps, which is unrealistic but not unphysical. Maybe its just the diagonal solver of the explicit term,...

Hey Hrushi,

I've got the same problem. Leaving this 4th order diffusion term out of the equation works and the results seem realistic. However I want to implement the whole equation so I am still...

Hi,

I am pretty far on implementing the Cahn-Hilliard model into the two-phase solver interFoam. The new solver compiles and it also runs. However I have to fix some problem with the alpha...
