The Wave Generated by a Fine Ship Bow

Abstract

The flow field near the bow of a ship has some characteristics of a high-Froude-number problem, even if ship speed is moderate. Some of these features can be predicted by slender-body theory if the assumptions are modified in the bow region to allow for the occurrence of longitudinal rates of change greater than normally assumed. Analytical results are derived for the case of a fine wedge-shaped bow, in which case a universal curve may be drawn within limits for the shape of the bow wave on the hull, regardless of speed, draft, or entrance angle. Some experimental results are shown which generally confirm the mathematical predictions.
