Comparisons between large eddy simulation (LES) and velocity measurements have been performed for the turbulent flow in a real shrouded rotor-stator configuration. To investigate turbulent flow regimes, LES numerical results (Spectral Vanishing Viscosity technique) and experimental data have been favourably compared for a large range of rotational Reynolds number in an annular cavity of curvature parameter Rm=1.8 and of aspect ratio G=5. All the characteristics of 3D turbulent boundary layers have been found and coherent structures have been shown under the form of annuli or spiral arms.
