hi everybody.
I have to simulate an air-entraining vortex using a cylinder intake connected to a reservoir.
Which Physics Model should I active despite of gravity and viscosity?
Are Air entrainment, drift flux and density evaluation required?

*the intake has a definite discharge. I select "volume flow rate" for outlet discharge, but I can't set a negative discharge. what should i do?

sorry for my bad english
thanks
