Water waves and integrability [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2007 Euler's equations describe the motion of inviscid fluid. In the case of shallow water, when a perturbative asymptotic expansion of Euler's equations is considered (to a certain order of smallness of the scale parameters), relations to certain integrable equations emerge.

Control of the Swell by an Array of Helmholtz Resonators
Crystals, 2021 We present a theoretical and experimental study of a resonator of the Helmholtz type for the control of the swell. An experimental demonstration of the shielding effect by a belt made of evenly distributed resonators is given.

Dynamic Analysis of a Tension Leg Platforms (TLPs) Inspired by Parallel Robotic Manipulators
IEEE Access, 2020 Dynamic performance of a tension leg platform (TLP) is analyzed using a robotic manipulator approach. The TLP is vertically anchored to the seabed by twelve mooring lines. A triangular mooring line configuration is studied.

Rotational gravity-capillary waves generated by a moving disturbance
Selecciones Matemáticas, 2021 Nonlinear gravity-capillary waves generated by the passage of a pressure distribution over a sheared channel with constant vorticity are investigated. The problem is modeled using the full Euler equations.

Splash singularity for water waves [PDF]
Proceedings of the National Academy of Sciences, 2012 We exhibit smooth initial data for the two-dimensional (2D) water-wave equation for which we prove that smoothness of the interface breaks down in finite time. Moreover, we show a stability result together with numerical evidence that there exist solutions of the 2D water-wave equation that start from a graph, turn over, and collapse in a splash ...

Coastal Engineering Proceedings, 1986 Accurate numerical computations of wave trains with small modulations that grow are described. The range of wave steepness and modulation lengths that give breaking waves are determined. The number of wave crests is reduced for a time at greatest modulation but frequency downshifting is not observed. Near-breaking wave-group structure is always similar,

A Locally Disordered Metamaterial for Directing and Trapping Water Waves
Crystals, 2023 Manipulating the flow of water wave energy is crucial for ocean wave energy extraction or coastal protection, and the emergence of metamaterials paves a potential way for controlling water waves.

Numerical Study on Collisions of Solitons of Surface Waves in Finite Water Depth
Fluids, 2023 Head-on collisions between two solitary waves in the framework of the nonlinear Schrödinger (NLS) equation were investigated using the Fourier spectral method. When solitary waves undergo collision, the peak value of surface elevation (hereafter referred

Numerical Study on the Motion and Wave Loads of an Uncrewed Surface Vehicle Catamaran at Low Speed in Sea Waves [PDF]
Journal of Applied Fluid MechanicsModern ship designs are being developed for various purposes in uncrewed operation. In particular, low-speed uncrewed surface vehicle (USV) catamarans have been applied as rescued boats in recent years.
