Looks like a straightforward rotating frames of reference model. Have a look at the rotating machinery tutorials.

thank you for your answer, in this project I look for CL, CD and main shaft torque. do you have reference step to CFX-mesh?

Are the vanes zero thickness within the surrounding volume (AKA zero thickness baffles)? That is currently a problem for Workbench meshing (since the concept never existed for FEA). It has been fixed for 12.1, but in the mean time, you will need ICEM CFD or TGrid to model zero thickness Baffles, or you could give them some thickness so ANSYS Meshing (workbench) can handle them...
