Numerical simulation of wave breaking and wave runup in the nearshore zone

When the wave approaches to coast, the wave steepness, which is the ratio of wave height to water depth increases due to depth re-duction. This increase continues to a certain extent, until finally at this limit, the wave breaks. Wave breaking results in t ...

Antenna excitation of drift wave in a toroidal plasma

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Benoît Labit, Mario Ludovico Podesta, Francesca Maria Poli, Stefan Müller

In a magnetized toroidal plasma, an antenna tunable in vertical wave number is used to excite density perturbations. Coherent detection is performed by means of Langmuir probes to directly determine both the wave vector and the plasma response induced by t ...

Development of electrostatic turbulence from drift-interchange instabilities in a toroidal plasma

Ambrogio Fasoli, Mario Ludovico Podesta, Francesca Maria Poli

Electrostatic instabilities develop on TORPEX (TORoidal Plasma EXperiment) [A. Fasoli et al., Phys. of Plasmas, 13, 55902 (2006)] in the bad curvature region and propagate consistently with the drift wave dispersion relation. The wave number and frequency ...

Contractile floating barriers for confinement and recuperation of oil slicks

Azin Amini

Marine oil spills can cause serious environmental damages to natural resources and to those whose sustenance depends upon these resources. Unfortunately experience shows that even the best efforts have not prevented occasional occurrences of major accident ...

Nonlinear correlations in phase-space resolved fluctuations at drift wave frequencies

In an effort to better understand plasma transport, we measure fluctuations associated with drift instabilities resolved in the ion phase-space. Primary attention is given to fluctuations near the electron drift frequency where there are two general compon ...

On the stability of Reduced Basis methods for Stokes Equations in parametrized domains

Gianluigi Rozza

We present an application of reduced basis method for Stokes equations in domains with affine parametric dependence. The essential components of the method are (i) the rapid convergence of global reduced basis approximations – Galerkin projection onto a sp ...

Nonparallel spatial stability of shallow water flow down an inclined plane of arbitrary slope

Roll waves are known to occur in the frictional flow of a thin layer of water down an inclined solid surface. For a layer of constant depth, the formation of these waves on a solid plane with small slope angle have been explained as a hydrodynamic instabil ...

Nodal DG-FEM solution of high-order Boussinesq-type equations

Jan Sickmann Hesthaven

A discontinuous Galerkin finite-element method (DG-FEM) solution to a set of high-order Boussinesq-type equations for modelling highly nonlinear and dispersive water waves in one horizontal dimension is presented. The continuous equations are discretized u ...

Efficiency of Brushwood fences in shore protection against wind-wave induced erosion

Selim Sayah

Shore protection in confined water bodies is of major importance in Switzerland where many lakes suffer severe shore erosion. It occurs mainly in shallow zones due to several reasons such as: the fluctuations of the water level , the wind-wave impact durin ...

Tomography using multiple wavelengths in digital holography: Method, simulations and experiments

Christian Depeursinge, Tristan Colomb, Etienne Cuche, Frédéric Montfort, Florian Charrière

In this paper we present a method for tomographic imaging using multiple wavelengths in digital holographic microscopy. This method is based on the recording at different wavelengths equally separated in the k-domain, in off- axis geometry of the interfere ...
