Hello
I have a cooling intake geometry on an aircraft. However, I only know the mass flow rate entering the intake. I don't have any other parameters. I don't even have the internal geometry of the intake. That is because, the intake is not important to me, but I need an 'exit' for the flow at that location so that a spillage does not affect the rest of the flow.

I don't think it is possible to define an internal face as a mass flow rate. However, I want to maintain the required mass flow rate through this channel that I have designed a simplistic approach to my cooling intake and exit.

Does anybody have any idea on how I can acheive this?
