Abstract

In order to achieve minimum resistance for a ship hull, we used an optimization algorithm and computational fluid dynamics to develop a hull-form design. An ITTC 1957 modelship correlation line formula was used to estimate the frictional resistance coefficient, and the wave-making resistance coefficient was evaluated by the Rankine source panel method with nonlinear free-surface boundary conditions. The geometry of the hull surface was represented and modified by a B-spline surface-modeling technique during the optimization process. Wigley and series 60 (CB = 0.60) hulls were selected to obtain an optimized hull that produces minimum resistance. Experimental tests were carried out for the modified series 60 (CB = 0.60) hull.
