Thin liquid FILM breaks with InterFOAM
Hi
I am simulating thin film flows driven by gravity on a vertical flat plate. I am using InterFoam with water-air mixture. The domain is initialized to a uniform film thickness over the length of the plate and uniform velocity. The pressure is initialized to zero everywhere. The simulation runs for a verry short while and just when waves start forming on the surface, the liquid film breaks. This is not consistent with results in the literature. Does anyone have experience with this? Does this have to do with my initalization? Thanks. |
Why did you initialize with uniform velocity?
Maybe a zero velocity suits better? |

The velocity is initialized to non zero values using Nusselt's theory but pressure is initialized to zero everywhere. Have you been able to benchmark any thin falling film results? I would like to know more about the problem set up. Maybe I am not setting up the problem well. Thanks |

OK. Thanks all the same. But have you successfully run thin film flows using InterFoam? do you experience any film breaks? |
