Statistics of weakly nonlinear waves on currents with strong vertical shear

Z Zheng, Y Li, SÅ Ellingsen - Physical Review Fluids, 2023 - APS
We investigate how the presence of a vertically sheared current affects wave statistics,
including the probability of rogue waves, and apply it to a real-world case using measured …

Wavefronts and modal structure of long surface and internal ring waves on a parallel shear current

C Hooper, K Khusnutdinova… - Journal of Fluid …, 2021 - cambridge.org
We study long surface and internal ring waves propagating in a stratified fluid over a parallel
shear current. The far-field modal and amplitude equations for the ring waves are presented …

Wavelet-based 2-D sea surface reconstruction method from nearshore X-band radar image sequences

P Chernyshov, T Vrećica, S Nauri… - IEEE Transactions on …, 2022 - ieeexplore.ieee.org
A 2-D wavelet-based radar analysis method for sea surface reconstruction is presented. The
wavelet-based sea surface reconstruction (WSSR) method resolves the traditional …

Profilometry: a non-intrusive active stereo-vision technique for wave-profile measurements in large hydrodynamic laboratories

L Savio, A Ahani, M Greco, BC Abrahamsen - Experiments in Fluids, 2024 - Springer
Profilometry is proposed as a novel non-intrusive image-based technique to capture the
profile of the air–water interface as a dense point cloud. It can be classified as an active …

Asymmetrical wakes over anisotropic bathymetries

LP Euvé, A Maurel, P Petitjeans… - Journal of Fluid …, 2024 - cambridge.org
The study investigates the impact of a vertically layered bathymetry, consisting of submerged
vertical plates, on a ship wake through theoretical analysis and experimental realization. For …

The Cauchy–Poisson problem for fluid with an ice cover in the presence of shear current (two-dimensional case)

IV Sturova - Fluid Dynamics, 2022 - Springer
The two-dimensional time-dependent problem of evolution of an initial perturbation in fluid
with an ice cover floating on the fluid surface is solved in the linear formulation. In the …

Long internal ring waves in a two-layer fluid with an upper-layer current

K Khusnutdinova - arXiv preprint arXiv:2006.03883, 2020 - arxiv.org
We consider a two-layer fluid with a depth-dependent upper-layer current (eg a river inflow,
an exchange flow in a strait, or a wind-generated current). In the rigid-lid approximation, we …

High-fidelity simulation of ship and linear shear current interaction

KM Phan, H Sadat - Ocean Engineering, 2022 - Elsevier
In this paper, the hydrodynamic performance of KCS (KRISO Container Ship) in the
presence of a non-uniform shear current is investigated for the first time using high-fidelity …

Ship's Wake on a Finite Water Depth in the Presence of a Shear Flow

I Shugan, YY Chen - Journal of Marine Science and Engineering, 2022 - mdpi.com
The ship's wake in the presence of a shear flow of constant vorticity at a finite water depth is
investigated by expanding the Whitham-Lighthill kinematic theory. It has been established …

Sheared free-surface flow over three-dimensional obstructions of finite amplitude

AH Akselsen, SÅ Ellingsen - Journal of Fluid Mechanics, 2019 - cambridge.org
When shallow water flows over uneven bathymetry, the water surface is modulated. This
type of problem has been revisited numerous times since it was first studied by Lord Kelvin …
