Ocean Engineering, 2020 In this paper, we first conduct an extensive review of published experimental studies on the added resistance of a ship in waves to establish a common database. The data was enhanced by unpublished data from joint industry projects.

Added resistance of ships in waves†
Ship Technology Research, 2015Added resistance of ships in waves is determined by a newly developed potential flow method, a Rankine source method, a strip method, and by RANS (Reynolds-averaged Navier-Stokes) equations solvers. For 10 ships, results of all these methods are compared with each other, with published computed and experimental results, and with approximation formulae ...

Numerical Prediction of the Added Resistance of Ships in Waves
Volume 2: CFD and VIV, 2014The added resistance in waves is computed for different ship types using two different Reynolds-Averaged Navier-Stokes Equations (RANSE) solvers, namely Comet and interFoam (OpenFOAM). Hence, the RANS equations are implicitly coupled with the non-linear equations of motions for six degrees of freedom and the solvers are extended by algorithms for mesh ...

Simulation of Added Resistance in High Waves
Volume 11: Prof. Robert F. Beck Honoring Symposium on Marine Hydrodynamics, 2015A vessel traveling across the sea experiences waves. The waves produce forces on the vessel resulting in added resistance. The forces are caused by the combination of wave and vessel motion. A variety of methods for prediction of added resistance in waves exists. The complexity and accuracy varies significantly. This paper focuses on numerical solution

The Exact Calculation of the Added Resistance in Waves
Volume 12: Vibration, Acoustics and Wave Propagation, 2012The exact calculation of the added resistance in waves is a seakeeping problem of high interest due to economic effect on ship exploitation. In this paper an open uniform B-spline based method is developed to calculate added resistance. Initially this method applied to calculate velocity potential and Kochin functions that are necessary for calculation

Prediction of added resistance of ships in waves
Ocean Engineering, 2011The prediction of the added resistance of ships in waves is a demanding, quasi-second-order seakeeping problem of high practical interest. In the present paper, a well established frequency domain 3D panel method and a new hybrid time domain Rankine source-Green function method of NTUA-SDL are used to solve the basic seakeeping problem and to calculate

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 ...

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 ...

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 ...

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 ...
