FAN simulation with inhomgen Temperature
I simulate a fan with an inhomogeneous temperature source in front of it. The rotation of the fan is simulated with MRF and also as a rigid body motion.
The MRF simulation shows that the heat is transferred against the rotation direction of the fan. The unsteady simulation transports the heat in the right direction.
So I am searching for the factor of this behavior, but until now I couldn't find a mistake in the simulation and some literature about this problem of the MRF.
Someone knows this problem and/or knows some literature about this behavior?
Can you put a picture from your domain.
Have you checked if the gravity direction is correct?
Have you selected air as an ideal gas/real gas?
