Do transience gravity waves in a shear flow break?
(John Wiley & Sons Ltd, 2008-07-10)
The propagation of transient gravity waves in a shear flow towards their critical levels is examined using a ray tracing approximation and a higher-degree (quasi-optic) approximation. Because of its transient forcing, the ...
On exact boundary controllability for linearly coupled wave equations
(Academic Press Inc. Elsevier B.V., 2014)
Stability properties of periodic traveling waves for the intermediate long wave equation
(European Mathematical Soc, 2017-01-01)
In this paper we determine orbital and linear stability of a class of spatially periodic wavetrain solutions with the mean zero property related to the intermediate long wave equation. Our arguments follow recent developments ...
Discontinuous Galerkin methods for solving the acoustic wave equation
(Asociación Argentina de Mecánica Computacional, 2013-11)
In this work we develop a numerical simulator for the propagation of elastic waves by solving the one-dimensional acoustic wave equation with Absorbing Boundary Conditions (ABC’s) on the computational boundaries using ...
Onset of Faraday waves in a liquid layer covered with a surfactant with elastic and viscous properties
(American Chemical Society, 2007-12)
In this work, we analyze the formation of Faraday waves on the free surface of a liquid layer covered by an insoluble surfactant. The linear analysis that is conducted includes the effects of both surface elasticity and ...
EXPLICIT REPRESENTATION FOR THE INFINITE-DEPTH TWO-DIMENSIONAL FREE-SURFACE GREEN'S FUNCTION IN LINEAR WATER-WAVE THEORY
(SIAM PUBLICATIONS, 2010)
In this paper we derive an explicit representation for the two-dimensional free-surface Green's function in water of infinite depth, based on a finite combination of complex-valued exponential integrals and elementary ...
Surface waves propagating on a turbulent flow
(AMER INST PHYSICS, 2016)
We study the propagation of monochromatic surface waves on a turbulent flow of liquid metal, when
the waves are much less energetic than the background flow. Electromagnetic forcing drives quasitwo-
dimensional turbulence ...
