The investigation of a propeller wake is carried out in a cavitation tunnel using particle image velocimetry. To achieve high spatial resolution, a multigrid adaptive cross-correlation algorithm is used for image analysis. The contributions of the viscous wake, originated by the boundary layer on the blades of the trailing vortex sheets, as well as of the vorticity distribution are resolved and discussed for different angular positions of the blade. The near wake flow is characterised by strong deformations, due to the bending of the blade wake sheets, to the contraction of the slipstream and to the trajectory of the tip vortex. The turbulent diffusion and the viscous dissipation rapidly lead to broadening and decay of the trailing edge wake. Furthermore, secondary tip vortex structures are also pointed out.
