Hydrodynamic optimization of ship hull forms
Applied Ocean Research, 2001Abstract An extremely simple CFD tool is used to compare the calm-water drags of a series of hull forms and to define ‘optimized’ monohull ships for which the total (friction+wave) calm-water drag is minimized. The friction drag is estimated using the classical ITTC formula. The wave drag is predicted using the zeroth-order slender-ship approximation.

Submarine Hull Form Optimization Case Study
Naval Engineers Journal, 2000ABSTRACTThe potential benefits of full stern submarines are investigated. First, a parametric‐based arrangement study is conducted. The results of this study yield two variants which are identical in terms of installed horsepower and mission hardware, but with deferent stern taper.

Hull Form Optimization for Hydrodynamic Performance
Marine Technology and SNAME News, 2004A method for optimizing hull forms with respect to their hydrodynamic performance in calm and rough water is presented. The method is based on an initial optimization of a parent hull form for seakeeping and the improvement of the resulting optimum hull form for calm water resistance. In the first part of the method, variant hull forms differing from a

Multi-fidelity Bayesian Optimization of SWATH Hull Forms
Journal of Ship Research, 2019This study presents a multi-fidelity framework that enables the construction of surrogate models capable of capturing complex correlations between design variables and quantities of interest. Resistance in calm water is investigated for a SWATH hull in a multidimensional design space using a new method to derive high-quality response surfaces through ...

Hull-form optimization in calm and rough water
Computer-Aided Design, 2010The paper presents a formal methodology for the hull form optimization in calm and rough water using wash waves and selected dynamic responses, respectively. Parametric hull form modeling is used to generate the variant hull forms with some of the form parameters modified, which are evaluated in the optimization scheme based on evolutionary strategies.

Numerical hydrodynamic optimization of a tanker hull form
2015The knowing of the flow around the ship and her resistance components is very important in the hull form de-velopment, as the design of a low resistance ship remains a permanent problem in ship hydrodynamics. At pre-sent the computational tools based on numerical methods can be efficiently used in ship hull form develop-ment, particularly at the early ...

Hull Form Optimization of Trimaran Using Genetic Algorithm
2011 14th IEEE International Conference on Computational Science and Engineering, 2011In this paper a Trimaran hull form has been optimized to obtain low resistance hull. Hull portion consisting bow shape is taken into consideration for optimization. FLUENT software is used for calculating the total resistance of hull and genetic algorithm is used for the optimization.

Hull-form stochastic optimization via computational-cost reduction methods
Engineering with Computers, 2021The paper shows how cost-reduction methods can be synergistically combined to enable high-fidelity hull-form optimization under stochastic conditions. Specifically, a multi-objective hull-form optimization is presented, where (a) physics-informed design-space dimensionality reduction, (b) adaptive metamodeling, (c) uncertainty quantification (UQ ...
