forward curve centrifugal blower boundary condidions
 
Hi friends, I have a problem about simulation of a forward curve centrifugal blower 3D due to blade motionless

1- Blades don't rotate in rotating zone thus the flow is complex around blades, some fluid flows in the back direction interestingly

2- when I change moving referance frame to moving mesh, the fluid flows in right direction but blades don't rotate again

3- To sum up, I suspect either the blades don't rotate anytime because of flow is rotate (but there are some simulations when a examine in the google) or I have a problem about rotating zone

Do you have any idea about this problem?

Thanks for your interest, primarily!
