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 ...

Validation of added resistance in waves by tank tests and sea trial data
Ship Technology Research, 2021With the start of the EEDI (energy efficiency design index for new ships) regulations by the International Maritime Organization, a review of the analysis method for speed/power trials was required.

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 ...

Except for the ice-breaking capacity in the polar regions, a Polar Research Vessel (PRV) should also have good navigation performance in open water. Three conventional ships are used for comparison to study the added resistance and vertical motions of ...

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

A Study on the Added Resistance Performance of Catamarans in Waves
Volume 11A: Honoring Symposium for Professor Carlos Guedes Soares on Marine Technology and Ocean Engineering, 2018The added resistance of a catamaran advancing in waves is investigated in the framework of a non-viscous potential theory. A linear Boundary Element Method (BEM) is used for the first order seakeeping prediction and the mean longitudinal component of the second-order steady-state force is computed by using a near-field method.

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
