Surface tension modelling
 
2 Attachment(s)
I am modeling multiphase flow, with water (green) , oil (red) , air (blue). The water is flowing through the oil, but I am having results where the air is coming in between water and oil. and separating water and oil. I think it's because of surface tension modeling.

Why is the air coming in between water and oil? Thanks

What's the outlet boundary condition?

The air might be coming in between water and oil due to entrainment.
