Research on the impact of ship traffic flow on the restricted channel segment of the middle Yangtze River based on traffic wave theory

open access: yesSN Applied Sciences, 2021
Abstract On the basis of the influence of dry season on ship traffic flow, the gathering and dissipating process of ship traffic flow was researched with Greenshields linear flow—density relationship model, the intrinsic relationship between the ship ...

Spectrograms of ship wakes: identifying linear and nonlinear wave signals [PDF]

open access: yes, 2016
A spectrogram is a useful way of using short-time discrete Fourier transforms to visualise surface height measurements taken of ship wakes in real world conditions.

Wave effects on the turning ability of an ultra large container ship in shallow water [PDF]

open access: yes, 2019
The influence of waves on ship behaviour can lead to hazardous scenarios which put at risk the ship, the crew and the surroundings. For this reason, investigating the effect of waves on manoeuvring is of relevant interest.

Proposal of Optimal Operation in Ship Rolling Motion Considering Sea State Conditions

open access: yesJournal of Marine Science and Engineering, 2022
Most of the research on ship rolling motion concerns a specific type of ship, such as containerships, or analyzes sailing during certain wave characteristics, rather than the full spectrum of waves that can be encountered during the entire sea route.

Linear "ship waves" generated in stationary flow of a Bose-Einstein condensate past an obstacle [PDF]

open access: yes, 2006
Using stationary solutions of the linearized two-dimensional Gross-Pitaevskii equation, we describe the ``ship wave'' pattern occurring in the supersonic flow of a Bose-Einstein condensate past an obstacle.

Ship waves: the calculation of wave profiles [PDF]

open access: yesProceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1932
1. The surface disturbance produced by a ship is usually analysed into two parts : one is called the local disturbance and the other forms the wave pattern, the supply of energy required for the second part giving rise to the wave resistance of the ship.

Basic models of farfield ship waves in shallow water

open access: yesJournal of Ocean Engineering and Science, 2018
Basic models of the farfield waves created by a monohull ship or a catamaran that travels at a constant speed in calm water of uniform finite depth are considered.

Numerical Study on the Green-Water Loads and Structural Responses of Ship Bow Structures Caused by Freak Waves

open access: yesApplied Sciences, 2023
In recent decades, freak waves, characterized by their unusual high amplitude, sharp crest, and concentrated energy, have attracted researchers’ attention due to their potential threat to marine structures.

Rogue Waves: From Nonlinear Schrödinger Breather Solutions to Sea-Keeping Test [PDF]

open access: yes, 2013
Under suitable assumptions, the nonlinear dynamics of surface gravity waves can be modeled by the one-dimensional nonlinear Schrödinger equation. Besides traveling wave solutions like solitons, this model admits also breather solutions that are now ...

Observation of surface wave patterns modified by sub-surface shear currents [PDF]

open access: yes, 2019
We report experimental observations of two canonical surface wave patterns --- ship waves and ring waves --- skewed by sub-surface shear, thus confirming effects predicted by recent theory.
