Wave-reducing Stern Flap on Ship Convoys to Protect Riverbanks

Anton Schleiss, Giovanni De Cesare, Michael Pfister, Robin Amacher, Théodora Cohen Liechti

Inland navigable waterways are significant in cargo transport and leisure activities. In parallel, these channels and rivers often suffer from the ship traffic, as the generated waves may damage waterway banks, along with their riparian fauna. As a consequ ...

On global regularity for systems of nonlinear wave equations with the null-condition

Joachim Krieger, Aparajita Dasgupta, Can Gao

In this note we combine a recent result by Geba [2] on the local wellposedness theory of systems of nonlinear wave equations with

Damage pattern and damage progression on breakwater roundheads under multidirectional waves

Francesco Comola, Lorenzo Martinelli

An experimental model test study is carried out to investigate damage pattern and progression on a rock armoured breakwater roundhead subjected to multidirectional waves. Concerning damage pattern, the most critical sector is observed to shift leeward with ...

Surface wave dynamics in orbital shaken cylindrical containers

Florian Maria Wurm, Mohamed Farhat, Danail Obreschkow, Matthieu Dreyer, Stéphanie Tissot, Martino Reclari

Be it to aerate a glass of wine before tasting, to accelerate a chemical reaction, or to cultivate cells in suspension, the “swirling” (or orbital shaking) of a container ensures good mixing and gas exchange in an efficient and simple way. Despite being us ...

Nondispersive Decay For The Cubic Wave Equation

Roland Donninger

We consider the hyperboloidal initial value problem for the cubic focusing wave equation (-partial derivative(2)(t) + Delta(x))nu(t, x) + nu(t, x)(3) = 0, x is an element of R-3 Without symmetry assumptions, we prove the existence of a codimension-4 Lipsch ...

Local versus nonlocal barycenttic interactions in 1 D agent dynamics

Max-Olivier Hongler, Olivier Gallay, Roger Filliger

The mean-field dynamics of a collection of stochastic agents evolving under local and nonlocal interactions in one dimension is studied via analytically solvable models. The nonlocal interactions between agents result from (a) a finite extension of the age ...

Existence and conditional energetic stability of three-dimensional fully localised solitary gravity-capillary water waves

Boris Buffoni

In this paper we show that the hydrodynamic problem for three-dimensional water waves with strong surface-tension effects admits a fully localised solitary wave which decays to the undisturbed state of the water in every horizontal direction. The proof is ...

On the stability of travelling waves with vorticity obtained by minimization

Boris Buffoni

We modify the approach of Burton and Toland Comm. Pure Appl. Math. LXIV. 975-1007 (2011) to show the existence of periodic surface water waves with vorticity in order that it becomes suited to a stability analysis. This is achieved by enlarging the functio ...

Two-phase flow modeling of the influence of wave shapes and bed slope on nearshore hydrodynamics

David Andrew Barry, Roham Bakhtyar, Amir Mehdi Razmi

An Eulerian two-phase flow model (air-water) was used to simulate nearshore hydrodynamic processes driven by wave motion. The flow field was computed with the Reynolds-Averaged Navier-Stokes equations in conjunction with the Volume-Of-Fluid method and the ...

Transport of variable-density solute plumes in beach aquifers in response to oceanic forcing

David Andrew Barry, Alessandro Brovelli, Roham Bakhtyar, Clare Robinson

A comprehensive numerical study was undertaken to investigate transport of a variable-density, conservative solute plume in an unconfined coastal aquifer subject to high and low frequency oceanic forcing. The model combined variable-density saturated flow ...
