But in your test case there aren't rotating parts inside the rotor zone (the rotor is empty), so I think that this is not the correct approach to see is the vortex is broken at the interface.
Maybe that cells in the rotor are rotating with the assigned rotational velocity, so I wrote that it is correct that the vortex is broken.
To see if the cells are rotating post a contour plot of velocity in a xz plane.
I found out that I set the rotating axis origin in a wrong position. Now the result seems right to me.
