Flow simulation of Brake rotor
 

I am trying to simulate a disk brake rotor rotating in free air. I am using the SST model with solid in rotary motion@800 rpm and air at atmospheric pressure. The results show a significant high convective heat transfer co-efficient and no flow through the rotor vanes. Confused with this contradictory result. I am using mesh deformation in fluid domain to couple with rotating solid.

P.S. : I am a structural mechanics person but have to do this for a project. Please pardon for being naive here.

Can you provide more details? Like which package you are using for this simulation? What kind of deformation did you apply?
Is there any other velocity than rotational?
Are you intending to do heat transfer separately after taking htc's from this run?

I'm using the CFX module for a CHT analysis. So I'm not extracting the htcs. And there is no velocity other than the rotors angular velocity.

Can you post your convergence plot?
Snapshot of the mesh would also be useful if possible.

Here are the snaps for pressure & momentum convergence and turbulence. Also the setup window and mesh. I am pretty sure the setup is wrong. And also I am doing a transient analysis.

Thank you for your reply and help

Will suggest you one quick change, see if it works.
Let your solid be stationary and give your fluid volume either rotating mesh or rotating frame of reference.

Thanks Shrirang.
I will try this and share if it works.
