rotating case boundary conditions
 
I am trying to analyze a propeller in Fluent. I have a 1/10 pie slice, that includes one of the blades. I am using a pressure inlet, and pressure outlet, on the sides periodic condition, on the outside of the slice a slip wall, and then I have the fluid rotating at my desired rpms. Are these correct boundary conditions?

Also I understand the different reference frames that fluent uses, but what does fluent output the inertial frame, the rotating frame?

I've no idea of how fluent deals with rotating frames but concerning your BC I think that for the external part of the slice you should better have a pressure outlet rather than a slip wall.

Cheers,

Rob
