Chaotic sound waves in a regular billiard

Physical Review E, 2003
We present experimental results for the ultrasound transmission spectra and standing wave patterns of a rectangular block of fused quartz. A comparison is made between our data and an approximation of the theoretical staircase function for three-dimensional isotropic elasticity.

Spatially evolving regular water wave under the action of steady wind forcing

, 2021
The spectra plotted in this work demonstrate suppression of random wind-generated waves by a deterministic long wavemaker-generated wave in a moderately sized wind-wave facility. Experiments performed for a wide range of experimental conditions show that

Performance analysis of a floating breakwater integrated with multiple oscillating water column wave energy converters in regular and irregular seas

, 2020
Maritime structure integration is widely considered as a potential solution for reducing the high Levelised Cost of Electricity (LCOE) associated with Wave Energy Converter (WEC) technologies.

ON THE SIMULATION OF REGULAR WAVES IN A NUMERICAL WAVE TANK

Advances and Applications in Fluid Mechanics, 2018
The use of renewable sources for electricity generation has been accelerated because of high fuel prices of fossil fuels. In addition to this, the use of conventional fuel supplies is no longer able to cater for the ever increasing energy demands of the modern world which is experiencing an age of rapid expansion.

Numerical studies and proposal of design equations on cylindrical oscillating wave surge converters under regular waves using SPH

, 2020
An oscillating wave surge converter extracts energy from sea waves and converts it into electricity. Its main components are a flap, hinge, base, and power take-off system. In this paper, an oscillating wave surge converter comprising a cylindrical flap,

Scattering of regularized-long-wave solitary waves

Physica D: Nonlinear Phenomena, 1984
The Lagrangian density for the regularized-long-wave equation (also known as the BBM equation) is presented. Using the trial function technique, ordinary differential equations that describe the time dependence of the position of the peaks, amplitudes, and widths for the collision of two solitary waves are obtained.

Travelling Wave Solutions of the General Regularized Long Wave Equation

Qualitative Theory of Dynamical Systems, 2021
This paper studies the model of the general regularized long wave (GRLW) equation. The main contribution of this paper is to find that GRLW equation has extra kink and anti-kink wave solutions when $p = 2n + 1$, while it's not for $p = 2n$. The authors give the phase diagram and obtained possible exact explicit parametric representation of the ...

Wave Height and Planing Hull Wave Slams in Regular Waves

SNAME Chesapeake Power Boat Symposium, 2016
High-speed planing boats are subject to repeated slamming impacts. These impacts can cause structural damage and discomfort, or even injury, to passengers. The motivation for this research is to determine a relationship between wave height and vertical accelerations of planing crafts.
