Computational investigation of ship propulsion performance in rough seas [PDF]

, 2016
In this paper, the performance of a merchant vessel propulsion system during acceleration is evaluated under different sea state conditions. The various parts of the main propulsion system have been modelled by using a mean value approach for the engine ...

The effect of lift on the wave-making resistance of multi-hull craft [PDF]

, 2007
A potential based panel method is presented to estimate the wave-making characteristics of multi-hull craft. In order to simulate the lifting potential flow around the sub-hulls, the method adopts mixed source/doublet distributions on the sub-hulls and ...

Asymptotic models for the generation of internal waves by a moving ship, and the dead-water phenomenon

, 2011
This paper deals with the dead-water phenomenon, which occurs when a ship sails in a stratified fluid, and experiences an important drag due to waves below the surface.

A Multi-Objective Optimization Environment for Ship-Hull Design Based on a BEM-Isogeometric Solver [PDF]

International audienceWe present a ship-hull optimization environment integrating modern opti- mization techniques, a parametric ship-hull model and a novel BEM solver for the cal- culation of ship wave resistance. The environment is tested for a pair of

ADDED RESISTANCE OF SHIPS IN QUARTERING SEAS

, 2013
In this paper, the 3D panel method of NTUA-SDL for calculating the added resistance of a ship in bow seas has been extended and validated for the quartering seas case. At first we studied the drift force on a semi-submersible in quartering seas.

Numerical Analysis of Water-Injection Drag Reduction on a Flat Plate

Journal of Marine Science and Engineering
Water injection is a promising alternative to traditional air lubrication for reducing ship hull drag and improving energy efficiency. Addressing the limited research on the efficacy of water lubrication on ships, this novel study is the first to ...
