An interior is just a meshed surface in the model - you can monitor the flow on it, but that's it. If you want to suck flow out & blow it into the domain at pre-set rates you'll need (velocity) flow boundaries. Using paired boundaries so you suck in some kg/s and then return the same kg/s at a higher temperature is allowed, and Expressions will make this much easier than would be the case with UDFs.
