OPTIMIZATION OF BOW BULB CONFIGURATIONS ON THE BASIS OF MODEL WAVE PROFILE MEASUREMENTS

A semi-empirical method for designing bow bulb configurations of low wave resistance on the basis of wave profile measurements in the model basin is critically examined. The fundamental assumption under investigation is the principle of linear superposition of the individual free-wave spectra of the main hull and the bow bulb to yield the free-wave spectrum of the composite bulbous bow hull form. It is concluded that wave resistance predictions based on this hypothesis are reasonably accurate so as to encourage the use of this method as a heuristic design tool. (Author)
