Description | ||||||
Due to the increase of maritime transportation volume day by day it is necessary to design a ship hull having large carrying capacity with low resistance. For this purpose, the authors propose innovative concepts of Ultra Large Block coefficient Ship (ULBS). In this paper, its concepts and study plans are shown, and its bow wave breaking phenomena are investigated as one of the fundamental studies on ULBS hull form. As experimental studies, wave breaking surface areas caused by ULBS models are measured. As theoretical ones, wave making resistance coefficients and distributions of free surface elevation are evaluated by means of Rankine source method, and distributions of free surface disturbance function D(x,y) are evaluated by means of Baba's low speed theory. Various parameters related to the wave breaking phenomena are investigated in comparisons between experimental and theoretical results. Under these investigations, it can be concluded that theoretical results based on wave making resistance coefficients, surface integrals of the square of free surface elevation and surface integrals of the square of free surface disturbance function have strong elations to wave breaking surface areas. |
