Hi, I am still new to fluent and would like to seek advice on the simulation.
Currently, I would like to simulate 3D bubble column with VOF. My dimension of the column is height=60cm, diameter=20cm. My mesh size is around 60k cells, is that sufficient to capture the bubble formation? Can I actually get the 3D fluent tutorial from online? I know there is one for 2D bubble column, but for 3D, I am trying to get the animation for the bubble formation. Anyone can give me some advice?
I know that I have to specify surface tension, and I search online the normal value would be 0.072N/m2, is that right? What velocity do I need to set?
I think bubble column is not a hot topic and the simulation has been done for years. If you have one, do you mind to share your experience and result?

60k mesh is too fine, you have to set the mesh size according to the hole size of the sparger. but as a default, I usually set the mesh size to 1mm. 0.0735 for surface tension would be fine.
