Hi Everyone!

Please, Could you help me with my simulation in Fluent? I am engaged in simulating of sewage aeration in open channel flow, where water moves with defined velosity. I've specified inlet and outlet for water, and inlet surface for air (Eulirian - Eulirian, bubbles, d=0.0025 mm) But How Can I specify an outlet for air? If i specify outlet for air like pressure outlet on surface (free surf of my channel), it will be outlet for water too, but it will be incorrect study.

Are there any decisions for this problem?

I hope it will be appropriate image to undestand my problem. Surface C is a surface of water in my channel and usually is defined like symmetry BC, but I can't do as well because it's a surface, where air should vanish.
descrete models aren't appropriate either.
