Default Ducted propeller, Boundary conditions
Posts: n/a

I have a problem in setting up boundary conditions for a simulation of a ducted propulsive propeller. After testing a third of the model with periodic conditions (which didn't worked at all) I want to simulate now a complete model. My propeller is a moving wall who is turning with a moving reference frame, the duct is a stationary wall. The volume around is a cylinder. Who has experiences in such applications and can give me some useful tips?

Regards, Johannes
