Hi,
i am involved in a R&D project on bubble curtains.
First of all i want to validate the methodology to create the air bubble and especially the velocity field inducedny the bubble rising.
I found different papers and about this topic i found also the experimental results.
The model is made of a rectangulare domain with an airbubble at the bottom (slightly above the bottom) in a quiescent water: the bubble rise to buoyancy force.
the setup of simulations a multiphase model: VOF+Level set functions. I am using the same setup of the paper and my proble is aùhow to recognise the uprise velocity of air bubble because the bubble breaks.
Does someone can help me?
Thank you very much

vinerm will become famous soon enough
You have not mentioned what help do you require? Do you need help with setup or with convergence or something else?
