Abstract
Bow and shoulder wave-breaking flow, generated by a fast displacement ship model (INSEAN model 2340) has been investigated. Both the mean and the rms values of the wave height have been obtained measuring point by point by means of a finger probe. The intensity of the breaking is highlighted by the highest values of the wave fluctuations nearby the bow wave crest. The velocity field under the free surface has been measured 0.2 Lpp downstream the fore perpendicular by means of 5-hole Pitot probe. These measurements have been performed just downstream the maximum of the wave fluctuation. Very detailed database for CFD validation has been carried out for the wave height. The measured velocity field completes the database and highlights interesting flow features. Uncertainty assessment of the wave height and velocity results has been performed following the AIAA Standards S-071-1995.
