An experimental investigation of the propeller wake has been performed in a cavitation tunnel using LDV and flow visualizations. The objective is the hydrodynamic and geometrical characterization Of the wake flow field and its downstream evolution features. Implications of the physical aspects For wake modeling are also highlighted. The viscous blade wake, originating in the boundary Layer on the blade surfaces, the trailing vortex sheets, due to the radial gradient of the bound Circulation, as well as the turbulence distribution are identified at the trailing edge and followed.
