[HTML][HTML] Scale effects on the wave-making resistance of ships sailing in shallow water

Q Zeng, R Hekkenberg, C Thill, H Hopman - Ocean Engineering, 2020 - Elsevier
The conventional extrapolation of ship resistance from model tests to full scale presumes
that the coefficient of wave-making resistance (C w) depends on the Froude number only …

Plasmon wake in anisotropic two-dimensional materials

ZL Mišković, M Moshayedi - Physical Review Research, 2023 - APS
We use analytically tractable dielectric response models, which are supported by ab initio
calculations for anisotropic two-dimensional (2D) materials and quasi-2D metals that host …

An Earth-fixed observer to ship waves

H Liang, Y Li, X Chen - Journal of Fluid Mechanics, 2024 - cambridge.org
This work deals with the linear surface waves generated by a vessel advancing at a constant
forward speed. These waves, known as ship waves, appear stationary to an observer on the …

Spectrograms of ship wakes: identifying linear and nonlinear wave signals

R Pethiyagoda, SW McCue… - Journal of Fluid Mechanics, 2017 - cambridge.org
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. For a steadily …

Numerical simulation of the Kelvin wake patterns

X Sun, M Cai, J Wang, C Liu - Applied Sciences, 2022 - mdpi.com
The ship wave is of great interest for wave drag and coastal erosion. This paper proposes a
mechanism of ship wave transformation to explore the effects of ship speed and ship size on …

Time-frequency analysis of ship wave patterns in shallow water: modelling and experiments

R Pethiyagoda, TJ Moroney, GJ Macfarlane, JR Binns… - Ocean …, 2018 - Elsevier
A spectrogram of a ship wake is a heat map that visualises the time-dependent frequency
spectrum of surface height measurements taken at a single point as the ship travels by …

Transient wave resistance upon a real shear current

Y Li, BK Smeltzer, SÅ Ellingsen - European Journal of Mechanics-B/Fluids, 2019 - Elsevier
We study the waves and wave-making forces acting on ships travelling on currents which
vary as a function of depth. Our concern is realism; we consider a real current profile from …

Viscous effects on the fundamental solution to ship waves

H Liang, X Chen - Journal of Fluid Mechanics, 2019 - cambridge.org
The fundamental solution to steady ship waves accounting for viscous effects (the viscous-
ship-wave Green function) is investigated within the framework of the weakly damped free …

Kelvin wake pattern at small Froude numbers

R Pethiyagoda, TJ Moroney, CJ Lustri… - Journal of Fluid …, 2021 - cambridge.org
The surface gravity wave pattern that forms behind a steadily moving disturbance is well
known to comprise divergent waves and transverse waves, contained within a distinctive …

Approximate ship wake solution for fast computation

PHY Lo - Ocean Engineering, 2021 - Elsevier
An approximate ship wake solution that accurately predicts both the wake patterns and the
wake amplitudes in any water depth is proposed and validated. Derivation based on the …
