Appreciate any help or suggestions on the below case.

I am trying to run 2-phase flow VOF model.
Oil flowing through pipe into air cavity.I know the required flowrate that I should achieve through the pipe (gravity included).I have the pressure value for the cavity.
BCs pressure inlet for oil inlet and pressure outlet for air outlet and wall for the rest of model.
I would like to see if the diameter is good enough to hold the required flowrate.Also expecting to see some air flow back.
When I run with the above conditions (setting gauge pressure on pressure outlet to cavity pressure) it right away diverges.
Can anyone help me how to validate the results???


Thanks
