First for rotating zone we need to define a rotating region. For that we created a closed cylinder around the rotor by editing your geometry. This solid is called solid_0.
Then mesh the geometry simply as you do in normal cases but add another mesh refinement for previously made cylinder solid_0 and mark the create cell zone to true.
In Simulation setup we used steady state analysis and added the rotation of the turbine using MRF Multi Reference Frame Method (mesh is not physically moving but it adds the rotation effect)
Then set the initial and boundary conditions according to your application. Then in advance concepts options Rotating Zones and select MRF, give the rotation center which is any point on the rotation axis, specify the rotation axis and give the angular velocity.
Here are simple plots of a simulation run.
You can also calculate the other permeates, like force on the rotor, by adding options in Result Control.
And then you can post process these parameters
