Calculation of Added Resistance in Oblique Waves

Journal of the Society of Naval Architects of Japan, 1980
The formula for the added resistance of a ship in oblique waves is simplified by the assumption of high frequency of encounter. Numerical computations by the simplified formula are carried out with respect to the Series 60, CB=0.70 model at various heading angles to the wave.

Effects of a Bulbous Bow Shape on Added Resistance Acting on the Hull of a Ship in Regular Head Wave

Journal of Marine Science and Engineering, 2021
In this study, the effect of bow shape on resistance acting on a hull in regular head waves was investigated by applying a commercial Computational Fluid Dynamics (CFD) code.

Environmental Aspects of Total Resistance of Container Ship in the North Atlantic

Journal of Sustainable Development of Energy, Water and Environment Systems, 2019
The total resistance of ship in waves is composed of calm water resistance and added resistance in waves. The added resistance in waves is one of the main causes of an involuntary speed reduction of a ship.

Analysis of Added Resistance in Short Waves

Journal of the Society of Naval Architects of Korea, 2015
In this study, the added resistance of ships in short waves is systematically studied by using two different numerical methods - Rankine panel method and Cartesian grid method - and existing asymptotic and empirical formulae. Analysis of added resistance in short waves has been preconceived as a shortcoming of numerical computation.

The impact of heat waves on mortality. [PDF]

, 2011
BACKGROUND: Heat waves have been linked with an increase in mortality, but the associated risk has been only partly characterized. METHODS: We examined this association by decomposing the risk for temperature into a "main effect" due to independent ...

On a New Formulation for Wave Added Resistance [PDF]

, 2023
Our objective is to present preliminary calculations using a new formulation for the wave added resistance recently derived by Kashiwagi [1]. This method is based on far-field momentum conservation with the far-field integrals moved to the body using Green’s second identity. An incomplete form of this formulation with body-surface integrals has existed

Bow hull-form optimization in waves of a 66,000 DWT bulk carrier

International Journal of Naval Architecture and Ocean Engineering, 2017
This paper uses optimization techniques to obtain bow hull form of a 66,000 DWT bulk carrier in calm water and in waves. Parametric modification functions of SAC and section shape of DLWL are used for hull form variation.

Effect of STEP for Reducing Added Resistance in Waves

Journal of the Japan Society of Naval Architects and Ocean Engineers, 2011
The present paper provides the results of an investigation on STEP (Spray Tearing Plate) for reducing the added resistance in waves.The research has been started to develop a device for suppressing spray; thin wave like a film that is generated around the bow above the waterline when a ship runs in waves.
