Results of an installed marine propeller wake survey, performed by means of stereo-PIV and LDV techniques, are presented. Measurements were carried out in phase with the propeller angular position along a transversal section of the wake, located in the close vicinity of the blade trailing edge. Both the techniques allow a suitable reconstruction of the propeller wake features and of the strong and complex interactions between the propeller itself and the hull wake. The present work is mainly focused in pointing out the capability of the measurement techniques in resolving the propeller wake especially for the application of Stereo PIV.
