Energy analysis of ship motion in waves and a novel method for predicting wave added resistance
The Physics of FluidsEnergy analysis of ship motion in waves is carried out, and a novel method to predict the corresponding wave added resistance is proposed in this paper. First, a semi-analytical three-dimensional translating and pulsating source method that accounts for ...

Added Resistance of Ships in Waves
Journal of Hydronautics, 1978A new method is presented for computing the added resistance of a ship advancing at constant mean speed and heading in regular waves. It is shown that the added resistance, even though it is a second-order quantity, can be expressed as a product of first-order terms that are all computed by computer programs presently in use for predicting the linear ...

Numerical and Experimental Analysis of Added Resistance of Ships in Waves
Volume 11: Prof. Robert F. Beck Honoring Symposium on Marine Hydrodynamics, 2015A RANS-based field method numerically predicted added resistance in regular head waves for a 14000 TEU containership (Duisburg Test Case) and a medium-size cruise ship. We concentrated our investigations on short waves. For different frequencies, we decomposed added resistance into diffraction and radiation force components, whereby diffraction forces ...

Numerical and Experimental Analysis of Added Resistance of Ships in Waves
Journal of Offshore Mechanics and Arctic Engineering, 2016Two Reynolds-Averaged Navier–Stokes (RANS) based field methods numerically predicted added resistance in regular head waves for a 14,000 TEU containership and a medium size cruise ship. Long and short waves of different frequencies were considered. Added resistance was decomposed into diffraction and radiation force components, whereby diffraction ...

A Rankine Panel Method for Added Resistance of Ships in Waves
Journal of Offshore Mechanics and Arctic Engineering, 2012A new Rankine panel method and an extended Reynolds-Averaged Navier–Stokes (RANS) solver were employed to predict added resistance in head waves at different Froude numbers of a Wigley hull, a large tanker, and a modern containership. The frequency domain panel method, using Rankine sources as basic flow potentials, accounts for the interaction of the ...

Study of Wave Added Resistance on Wigley Ship
Applied Mechanics and Materials, 2013Global warming is becoming a serious problem nowadays. The emissions of greenhouse gas from vessels draw great attentions. As a significant research part of vessel seakeeping performance, resistance capability exert pretty effect on energy consuming. A Wigley ship model is set as the object to compute constraint and free model in calm water and head ...

The added resistance of a moving ship in waves
International Shipbuilding Progress, 1972On the base of the method outlined in [1] more detailed analysis of the added resistance of ships in waves is shown. The practical estimation of the components of the added resistance is given. The comparison of the calculated and experimental results for the cargo ship is made also.
