Default volume-fraction

Hello everybody! I'am thinking about a problem based on the principle of a coaxial ejector (innerpipe water, outerpipe air). I have got massflow of water an air. Problem now: at boundary pressure outlet I need volume fraction air. Do I have to calculate it from my massflow?

Only if you expect recirculation at the outlet. Extend your physical domain to avoid recirculation at the outlet.
