Do you mean entrainment of air?
So you should first active air entrainment model available under the physics tab. then in analyze tab/2D plot/contour variable, choose vol. fraction of entrained air.

thank you very much
Do you know it can shows bubbles of air diffused in water due to areation, or not?

your welcome,
yes I think so. see also "difference between true vof and two-fluid vof" post.
