Numerical Simulation of Random Irregular Waves for Wave Generation in Laboratory Flumes

Time Domain Simulation of DP Semi-Submersibles in Numerical Wave-Tank for Large Nonlinear Random Waves

ABSRACT In deepwater, Dynamic Positioning (DP) is proved to be cost-effective for the station keeping and controlling of the floating structures. This paper will show that the DP simulation and control of a floating vessel can be achieved in a numerical wave-tank. The complex interaction of the wind, waves and current forces against the vessel is modeled for the required station positioning wit...

Wave Theory II — Numerical Simulation of Waves — (1) Weve Equations and Numerical Simulation of Waves

This course describes the fundamental theories of the numerical simulation methods of wave phenomena by using computers. In this first lecture, wave equations in different areas are briefly reviewed, and are generalized into the common equation. Then, the purposes and the advantages of the numerical simulation are described. Finally, the methods which are described in this course are introduced...

Laboratory simulation of magnetospheric chorus wave generation

Whistler mode chorus emissions with a characteristic frequency chirp are important magnetospheric waves, responsible for the acceleration of outer radiation belt electrons to relativistic energies and also for the scattering loss of these electrons into the atmosphere. A laboratory experiment (Van Compernolle et al 2015 Phys. Rev. Lett. 114 245002, An et al 2016 Geophys. Res. Lett.) in the larg...

Numerical Wave Flumes Based on Smoothed Particle Hydrodynamics

Iteration Coupling Simulation of Random Waves and Wave-Induced Currents

A two-way coupling algorithm for wave-current interaction is developed and implemented into a nearshore circulation model to investigate the effects of fully wave-current interaction on irregular wave transformation over an elliptic shoal. The wave field is simulated by a spectral wave model WABED, and the wave-induced current is solved by a quasi-three-dimensional model WINCM. The surface roll...
