Check the centre of rotation in CFX and compare with your geometry. At a guess the axis is not where you thought it was.

I still couldn't figure it out. Yes, probably it's because mismatch of the centers. However, the second image which I sent here shows that they match. And can you maybe be a little bit more specific how to check, please?

Set up will show the initial condition, which is from the CAD. In results it'll be wherever the spinning part finished up. In geometry find the centre of the turbine unit (you may need to slice/chop the model to create a vertex). I'm not sure how rotation is set in CFX, but it'll be defined in the fluid zone somewhere - that need to be the same as CAD value.
