Default marine propeller with sliding mesh

Hi ! I am simulating a marine propeller with the rudder blade, so : unsteady computation with sliding mesh. I made a cylinder interface around the propeller which separate the 2 fluid zones : "stator zone" and "rotor zone". The rotor fluid zone is a sliding mesh zone with the blade walls stationary. The computation looks good with evolutions of forces not too bad. My problem is about the path lines : they do not swirl enought for me !?? The mesh moves but it looks like the fluid does not move !! I don't understand....maybe I don't use correctly the sliding mesh.... Anyone can help me ?

Thanks.

Thierry.
