Particle Trajectories Beneath Fully Nonlinear Waves Generated by Horizontal Seabed Motion
João Vitor P. Poletto, David Andrade, Marcelo V. Flamarion +1
We investigate fully nonlinear water waves and fluid-particle dynamics generated by the horizontal motion of a seabed obstacle with prescribed time-dependent velocity. The governin…
Full Euler equations for waves generated by vertical seabed displacements
Joao Vitor Parada Poletto, David Andrade, Marcelo V. Flamarion +1
We present a novel numerical method for simulating the generation and propagation of surface gravity waves by vertical seabed displacements. The cornerstone of our method is the co…
A theoretical study of the air-sea drag-saturation in very strong winds
Michael Stiassnie, David Andrade
The goal of this note is to provide a theoretical explanation for the saturation of the drag coefficient in strong wind conditions. The hydrodynamic model under consideration takes…
The nonlinear Benjamin-Feir instability -- Hamiltonian dynamics, primitive breathers, and steady solutions
David Andrade, Raphael Stuhlmeier
We develop a general framework to describe the cubically nonlinear interaction of a unidirectional degenerate quartet of deep-water gravity waves. Starting from the discretised Zak…
A three dimensional Dirichlet-to-Neumann operator for waves over topography
David Andrade, André Nachbin
Surface water waves are considered propagating over highly variable non-smooth topographies. For this three dimensional problem a Dirichlet-to-Neumann (DtN) operator is constructed…
