hello,

I work on two-phase flow in a pipe. I used the application interFoam for it.
My problem is when I reduced the diameter of the results that I will not have a physical meaning. at any given time The results are correct (I will have well-formed bubble), but from some time t deviennemt dispersed bubbles.
the enclosed my results, can you tell me how I should fix this problem please?

Hello,
Could you sent a little more information? I just started working on a similar problem. I do not have results (yet), but maybe we can help each other.

Hello Lyna,
Without more information it is very impossible to help you. Please read the first item in the CFD online forum. (How to give enough info to get help).

With my simulation I tried to change the outlet boundary conditions and that helped.

Best regards
Wouter
