... by Proper Orthogonal Decomposition method. Combined with the multi-objective genetic algorithm, the optimal hulls with better comprehensive resistance performance are obtained, and optimization effect is analyzed through further verification. Furthermore, based on Proper Orthogonal Decomposition method...

... process of deformation and evaluation of the hull form was performed form the viewpoint of CFD simulation on a free-surface in the presence of regular waves. After that, a series of model tests were performed to confirm that the optimal hull form was improved not only in terms of the performance in waves...

When the Neumann-Michell (NM) theory is numerically implemented for ship waves, in order to overcome panel integral difficulty of wave component in the Green function over a 4-node panel, the analytical panel integral...

... by RANS-based solver, and the bulbous bow was optimized. Zhang, Ma, and Ji (2009) used Rankine source method to calculate the wave-making resistance and Non-Linear Programming (NLP) as the optimization algorithm to get the optimal hull form with minimum wave-making resistance. Yang and Huang (2016) used...

... reconstruction method to transform and express hull form, and then predicts the hydrodynamic performance of each hull form scheme with computational fluid dynamic methods. Finally, the optimal hull satisfying the constraint condition is obtained by the optimization algorithm. Current studies are usually aiming...

... as an initial hull. Three optimization cases are considered for reduced drag: the bow part of the initial hull as well as the stem profile are modified to generate an optimal hull with a bulbous bow; a stern end bulb is designed and attached to the initial hull to generate an optimal hull with stern end...

The shape of the two final optimized hull forms, corresponding to two different design speeds, are critically discussed against a conventional (reference) design by comparing predicted...

... of the target ship but also be applied to estimate the unknown hull form based on the reduced wave height. The optimal hull forms of minimizing wash wave for a typical catamaran in deep water at service speed and at the critical speed of shallow water are estimated, respectively. Moreover, the hull form...
