Emergence of Solitons from Irregular Waves in Deep Water

Journal of Marine Science and Engineering, 2021
Numerical simulations were performed to study the long-distance evolution of irregular waves in deep water. It was observed that some solitons, which are the theoretical solutions of the nonlinear Schrödinger equation, emerged spontaneously as irregular ...

Simulation of Irregular Waves in a Numerical Wave Tank

Polish Maritime Research, 2015
The time domain boundary element method was utilized to simulate the propagation of the irregular waves in a numerical wave tank. The problem was solved in a time-marching scheme, upon the irregular waves being fed through the inflow boundary, in which ...

Complex Rotating Waves and Long Transients in a Ring-Network of Electrochemical Oscillators with Sparse Random Cross-Connections

, 2016
We perform experiments and phase model simulations with a ring network of oscillatory electrochemical reactions to explore the effect of random connections and non-isochronocity of the interactions on the pattern formation.

Analysis of a Horizontal-Axis Tidal Turbine Performance in the Presence of Regular and Irregular Waves Using Two Control Strategies

Energies, 2019
The flow developed on a tidal site can be characterized by combinations of turbulence, shear flows, and waves. Horizontal-axis tidal turbines are therefore subjected to dynamic loadings that may compromise the working life of the rotor and drive train ...

Experimental laboratory waves with a plunger-type wavemaker in waves-against-flow conditions

Results in Engineering
In this paper, a series of experiments was conducted to further expand the experimental benchmark of tests for plunger-type wavemakers in a laboratory water channel. The tests focus on the generation of waves in waves-against-flow conditions to study the

A Critical Assessment of the Flux Transport Dynamo

, 2014
We first discuss how the flux transport dynamo with reasonably high diffusion can explain both the regular and the irregular features of the solar cycle quite well.
