An Experimental Study for Slamming Flow and Green Water on Deck Final Report

Abstract

The results of an experimental investigation on large-amplitude oscillations of an axisymmetric flared body in a free surface are presented here, the goal being to generate sets of quality experimental data, e.g. time~history measurements, for the study of slamming flows and green Water on deck, as well as comparison with time-domain numerical codes. The measured data include time histories of the prescribed displacement, the acceleration, the resultant force, and the wave elevation at several locations away from the body. Both the deck dry condition and green-water_on-deck cases are studied. A range of oscillation frequencies and amplitudes are covered to investigate steep waves, local wavebreaking, and spray sheets. Video recordings were also taken in each run to provide qualitative photographs for breaking wave profiles and contact line dynamics.
