EXPERIMENTAL MEASUREMENTS OF THE DEFORMATION OF REGULAR HEAD AND FOLLOWING SEAS BY A SHIP MODEL
Abstract
This report describes measurements of the changes in amplitude of regular head and following waves as they passed along the length of a ship model for model speeds zero, Froude number 0.1, and Froude number 0.3. In head seas the height of the incident wave diminished by some 20% to 40% as it passed along the length of the fully restrained model from bow to stern. In following seas the wave diminished by some 50%, from stern to bow when the ship speed was less than the wave group velocity, and from bow to stern when the ship speed was greater than the wave group velocity. These experimental results are generally in fair agreement with Grim's theoretical predictions. However, at forward speeds in head seas, there are local variations of wave height near the bow which are not predicted by the theory.
