Modeling of a windtunnel
 

I have my doubts modeling the inlet and outlet of a windtunnel. Can anybody tell me what are the best boundary conditions for these areas? Will a velocity inlet and a pressure outlet do the job?

I'd begin with that boundaries, and then would change if it doesn´t work.

it depends if the windtunnel is a supersonic or a subsonic one.

if you're modelling a subsonic windtunnel those boundary conditions are correct.
