I created a new simulation project called 'Ducted fan - CFD sim':
A 3d printed ducted fan
More of my public projects can be found here.
@Ali_Arafat - transient run seems to make troubles. Any hints?
Fine mesh run meanwhile also in there - yPlus actually is so low that the no wall function would be necessary to capture the boundary layer.
Pressure distribution on surface:
The possible problem could be that the mesh for the Rotating zone is merging with the casing. See snap below,
I suggest to have a clear gap of atleast 1-2 cells between the boundaries of AMI zone and casing.
I hope this helps.
Very cool. Was it possible make fan rotate in simulation?
With best regards,
Indeed the fan rotates using the so called Arbitrary Mesh Interface (AMI). You can find more information about AMI and Multi Reference Frame (MRF) here: Rotating zones - MRF & AMI
All the best!
