Hi  
I am calculating the power output of a wind turbine using ANSYS Fluent. I am using Multiple Frames, one is the moving/rotational frame, and the other one is stationary frame (outer frame), see attached picture please. 
 
I barely can find studies in the literature who used multiple frames (one rotational one stationary) together with the periodic boundary condition. I am using multiple frames together with the periodic boundary condition and my results are close to experimental results. I define periodic boundary condition for rotating/moving frame and stationary domain separately in the mesh interface section. For the rotatinal domain, I only define interfaces and wall (blade). Is there something wrong?

Thank you very much
 
Mehmet

Looks okay. Why do you think something is wrong?

For rotating machinery you can also have a look at CFX, which has specific turbo pre- and post-processing available.
