The top should be a single-phase gas mass flow outlet, well say 2kg/s ( I can work on those units later), and a pressure outlet for the liquid phase, only, at the bottom. The liquid inlet is self-explanatory with well say 1kg/s. I am thinking I enable back flow for the gas phase at the liquid pressure outlet and a mass flow outlet at the top for the gas phase, but I see Ansys doesn’t offer a mass flow outlet for the two phase. How would I accomplish this task?
