Models for Damped Water Waves [PDF]

open access: yesSIAM Journal on Applied Mathematics, 2019
In this paper we derive some new weakly nonlinear asymptotic models describing viscous waves in deep water with or without surface tension effects. These asymptotic models take into account several different dissipative effects and are obtained from the free boundary problems formulated in the works of Dias, Dyachenko and Zakharov (Physics Letters A ...

Nonlinear Waves Passing over Rectangular Obstacles: Multimodal Method and Experimental Validation

open access: yesFluids, 2022
We report a theoretical and experimental investigation of the propagation of nonlinear waves passing over a submerged rectangular step. A multimodal method allows calculating the first- and second-order reflected and transmitted waves.

Trimodal steady water waves [PDF]

open access: yes, 2014
We construct three-dimensional families of small-amplitude gravity-driven rotational steady water waves on finite depth. The solutions contain counter-currents and multiple crests in each minimal period.

Water waves and integrability [PDF]

open access: yesPhilosophical 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

open access: yesCrystals, 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

open access: yesIEEE 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

open access: yesSelecciones 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.

DNA waves and water [PDF]

open access: yes, 2010
Some bacterial and viral DNA sequences have been found to induce low frequency electromagnetic waves in high aqueous dilutions. This phenomenon appears to be triggered by the ambient electromagnetic background of very low frequency.

Transmission of Water Waves under Multiple Vertical Thin Plates [PDF]

open access: yes, 2018
The transmission of water waves under vertical thin plates, e.g., offshore floating breakwaters, oscillating water column wave energy converters, and so on, is a crucial feature that dominates the hydrodynamic performance of marine devices. In this paper,
