Wave runup on a surging vertical cylinder in regular waves
Applied Ocean Research, 2017Abstract The wave runup caused by a vertical cylinder surging in regular waves is studied both experimentally and numerically. The so-called DualSPHysics Smoothed Particle Hydrodynamics (SPH) code is used for the 3-D numerical modelling. A wide range of cylinder sizes and wave conditions is investigated with results comparing favourably between the ...

Nonlinear Reconstruction and Prediction of Regular Waves
Volume 5B: Ocean Engineering; Honoring Symposium for Professor Günther F. Clauss on Hydrodynamics and Ocean Engineering, 2022Abstract A method for the reconstruction of nonlinear ocean surfaces is presented and applied to regular waves. From random samples of surface elevation, the method reconstructs the nonlinear features of the observed waves by means of the High-Order Spectral approach.

Waves and Patterns on Regular Graphs
SIAM Journal on Applied Dynamical Systems, 2015The authors consider coupled phase oscillators on finite regular networks that can be thought of as approximating the surface of a sphere. Examples studied include the dodecahedron (20 nodes) and the buckyball (60 nodes) and various generalisations of these. For some networks and some coupling functions the authors can show that rotating wave solutions

Response of Modelled Ice Masses to Regular Waves and Regular Wave Groups
Proceedings OCEANS '83, 1983An experimental investigation to determine the maximum instantaneous velocities attainable by a range of ice masses in regular waves and regular wave groups has been conducted. Models constructed of paraffin wax were shown to attain velocities approximately equal to those of the particle velocities in regular waves, for model beam to wavelength ratios ...

TRANSFORMATION OF REGULAR WAVES.
Proceedings of the Institution of Civil Engineers, 1987Results are presented from calculations for shoaling waves using a development of Dean's non-linear stream function which display better agreement with previous experimental data for parallel waves in shallow water than other currently available theories. The results are presented in a manner suitable for design applications. In addition to wave height

Regularity Results for Nonlinear Wave Equations
The Annals of Mathematics, 1993We report on some recent progress on the Cauchy problem for semilinear wave equations \(u_{tt} - \Delta u + g(u) = 0\) in \(\mathbb{R}^n \times \mathbb{R}\) for smooth nonlinearities \(g\) of critical growth \(g(u) = u |u |^{2^* - 2}\) for large \(|u |\), where \(2^* = (2n)/(n - 2)\), and related problems. Our aim in this article is twofold.

Chaotic sound waves in a regular billiard
Physical Review E, 2003We 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.

ON THE SIMULATION OF REGULAR WAVES IN A NUMERICAL WAVE TANK
Advances and Applications in Fluid Mechanics, 2018The 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.

Scattering of regularized-long-wave solitary waves
Physica D: Nonlinear Phenomena, 1984The 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.
