Calculation of Added Resistance in Oblique Waves

open access: yesJournal 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.

Analysis of Added Resistance in Short Waves

open access: yesJournal 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.

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

open access: yesJournal 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.

On a New Formulation for Wave Added Resistance [PDF]

open access: yes, 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
