Empty rotating domain

I am facing a very annoying problem while using Fluent (no matter which version, I tried both 15.0.7 and 14.5). I just modelled an empty rotating cylinder, surrounded by a stationary rectangular domain, and immersed in an inviscid incompressible air flow. Giving, as inlet condition in the stationary rectangular domain, a velocity profile, what I get immediately after the cylinder is something like a wake, the velocity of the air coming out from this empty domain is more or less constant and doesn't follow anymore the inlet profile. This effect is negligible when I set a very low rotational speed of the cylinder, but it is strongly increased when the rotational speed goes up.
My interfaces are good, I used Multiple Reference Frames, not Mixing Plane!!!
Did anyone get the same error in the past?
Thanks in advance.
