In the multiphase flow calculation,I use "pressure outlet" boundary condition,but I find that a value named "backflow volume fraction" need to be set in the second phase panel,what mean is it? Is it right that the value being set as "1" means the second phase total reflux?

This is exactly what I'm trying to do. I'm dealing with a multiphase system that in the real world has a paper filter to stop the particulate or secondary phase. How would I represent this in the model?
