drag force model: Schiller-Naumann-pb

melj · January 30, 2020, 12:38

Hello

I am modeling a multiphase bubble column.

Could anyone please explain (or refer to an article that describes) the Schiller-Naumann-pb drag model? Checked in Fluent help but it has provided just a one-line description. Does it use the same formula as Schiller-Naumann?

Thank you. I will go through the paper.

Thank you vinerm. I went through the paper but the reference that the author has mentioned seems to be incorrect. I am not able to get further details. I am not able to find any paper that has used this model in bubble columns.

If anyone has found a paper related to Schiller Naumann-pb drag model in bubble columns, kindly share.

Yes, the reference appears to be wrong. Actually, it is 32 instead of 31.
