Wave runup on a surging vertical cylinder in regular waves

Applied Ocean Research, 2017
Abstract 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 ...

The influence of regular wave and irregular wave on the mechanical characteristics of a triple-cylinder bundle structure

Ocean Engineering, 2021
By using the open source DualSPHysics, the interaction between wave and a triple-cylinder bundle structure is numerically investigated. The wave is generated by applying the predefined function to the wave maker, and the free surface and the velocity of ...

CFD prediction of ship seakeeping behavior in bi-directional cross wave compared with in uni-directional regular wave

, 2021
The seakeeping behavior of a vessel in multi-directional wave differs significantly from that in uni-directional wave. Given that a vessel operates in multi-directional or short-crested waves during its whole service period, it is important to have a ...

Nonlinear Reconstruction and Prediction of Regular Waves

Volume 5B: Ocean Engineering; Honoring Symposium for Professor Günther F. Clauss on Hydrodynamics and Ocean Engineering, 2022
Abstract 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.

Effects of soft marine fouling on wave-induced forces in floating aquaculture cages: Physical model testing under regular waves

Ocean Engineering, 2021
Previous experiments on the fouling/current and fouling/wave interactions were mostly limited to two dimensional (2D) net panels or isolated twines. The current paper deals with the wave-induced forces/moments in three dimensional (3D) physical models of

Waves and Patterns on Regular Graphs

SIAM Journal on Applied Dynamical Systems, 2015
The 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, 1983
An 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, 1987
Results 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, 1993
We 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.
