Numerical study of the spectral 3-D Green's function singularities for piezoelectric SAW components
(2005)
This article deals with the numerical study of the singularities appearing in the spectral 3-D Green's function associated with the piezoelectric surface acoustic wave components (so-called SAW components). These electrical ...
Solitary waves on a free surface of a heated Maxwell fluid
(Royal Soc, 2009-01-08)
The existence of an oscillatory instability in the Benard Marangoni phenomenon for a viscoelastic Maxwell's fluid is explored. We consider a fluid that is bounded above by a free deformable surface and below by an impermeable ...

Experiments on generation of surface waves by an underwater moving bottom
(The Royal Society, 2015)
We report laboratory experiments on surface waves generated in a uniform fluid layer whose bottom undergoes an upward motion. Simultaneous measurements of the free-surface deformation and the fluid velocity field are focused ...
Surface wave energy absorption by a partially submerged bio-inspired canopy
(IOP Publishing, 2018-05)
Aquatic plants are known to protect coastlines and riverbeds from erosion by damping waves and fluid flow. These flexible structures absorb the fluid-borne energy of an incoming fluid by deforming mechanically. In this ...
An integrable evolution equation for surface waves in deep water
(Iop Publishing Ltd, 2014-01-17)
In order to describe the dynamics of monochromatic surface waves in deep water, we derive a nonlinear and dispersive system of equations for the free surface elevation and the free surface velocity from the Euler equations ...
A panel-Fourier method for free-surface flows
(ASME Amererican Society of Mechanical Engineering, 2000-12)
A panel-Fourier method for ship-wave flow problems is considered here. It is based on a three-dimensional potential flow model with a linearized free surface condition, and it is implemented by means of a low order panel ...
Interaction between wave and coastal structure: Validation of two lagrangian numerical models with experimental results marine 2011
(2011-12-01)
Numerical modeling of the interaction among waves and coastal structures is a challenge due to the many nonlinear phenomena involved, such as, wave propagation, wave transformation with water depth, interaction among ...

Experimental study of surface waves scattering by a single vortex and a vortex dipole
(2000)
Surface waves interacting with filamentary vortex offer an interesting tool to characterize static and dynamics of surface vorticity. An experimental study of the scattered wave by a single vortex as well as by a vortex ...
