PIV and LDV techniques applied to the analysis of an installed propeller wake

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.
