Unmatched circumferential velocities

I would like to double check regarding is the change in circumferential speed moving from results obtained from streamline analysis and those from CFD. According to definition, U is equal to the rotational speed (rad/s) times radius (m). If the same geometry is imported to AxCFD to be used with the boundary conditions from the turbine design stage then both a specific radius and the rotational speed are equal, however there is a disparity in results of circumferential velocities at same stations between streamline and CFD.
