Numerical and Experimental Analysis of Added Resistance of Ships in Waves

Volume 11: Prof. Robert F. Beck Honoring Symposium on Marine Hydrodynamics, 2015
A 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 ...

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, 2018
The 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.

Estimation of added resistance for large blunt ship in waves

Journal of Marine Science and Application, 2013
Under the background of the energy saving and emission reduction, more and more attention has been placed on investigating the energy efficiency of ships. The added resistance has been noted for being crucial in predicting the decrease of speed on a ship operating at sea.

The added resistance of a moving ship in waves

International Shipbuilding Progress, 1972
On 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.

Comparative study on computation of ship added resistance in waves

Ocean Engineering, 2013
Recently, the design of commercial ships that produce less greenhouse gas has been of great interest in naval architecture fields. Ship designers are asked to find optimum hull forms with minimum resistance in ocean waves. An accurate computation of added resistance, therefore, is getting more important for the prediction of power increase in random ...

Towards understanding the ship added resistance in waves

2016
Intuitive methods for the determination of the ship added resistance in waves date from the very beginning of the study of this complex physical problem. They were created in the absence of accurate analytical and numerical tools for the ship motion and present phenomenon analysis, particularly wave diffraction and radiation.

Numerical analysis of added resistance on ships in short waves

Ocean Engineering, 2014
In the present study, a Rankine panel method, which is based on the potential theory and a Cartesian-grid method, which solves the Euler equation directly, are applied to calculate ship motion and added resistance. In the Rankine panel method, a near-field method which calculates added resistance by integrating the second-order pressure on a body ...

A Parametric Prediction of Added Resistance in Waves

2012
The added resistance in waves is, from a practical viewpoint, a key issue when selecting the propulsive plant of ships. Despite the fact that normal sea conditions correspond very rarely to calm water, most of the optimisation work performed at a design stage on the hull and on the propulsion system of ships relates to the calm sea condition.

Experimental Research on Added Resistance of KVLCC2 in Short Wave Dominated Irregular Waves

Volume 3: Ocean Engineering; Polar and Arctic Sciences and Technology
Abstract In recent years, with the trend of larger and greener vessels, the issue of added resistance dominated by short waves in the operation of ultra-large ships in actual sea areas has attracted increasing attention. Towing tank experiments, as one of the important research methods, have traditionally focused on added resistance in ...
