Im looking at designing an aerator in a siphon system where the downward flow and low preassure in the pipe draws in the air through the aerator and draws the bubbly flow down the pipe with the water flow. The simulation of the multiphase flow on CFD could be simular to that of the fuel mix in a venturi. Any help would be appreciated.

hi,

There are examples of an air-bubble reactor in the CFX tutorials. Have you looked at that example?

Hey i have looked at the tutorial and worked through it however the example is looking at the upward bubbly flow and in the siphon system that i am looking at the bubbly flow is being forced into the downward flow.

Hi,

So can't you just change the boundaries around to suit your application? What specifically is the problem?
