A Hamiltonian-preserving Scheme for High Frequency Elastic Waves in Heterogeneous Media
We develop a class of Hamiltonian-preserving numerical schemes for high frequency elastic waves in heterogeneous media. The approach is based on the high frequency approximation governed by the Liouville equations with singular coefficients due to material interfaces. As previously done by Jin and Wen [10,12], we build into the numerical flux the wave scattering information at the interface, an...
متن کاملRecent computational methods for high frequency waves in heterogeneous media
In this note, we review our recent results on the Eulerian computation of high frequency waves in heterogeneous media. We cover three recent methods: the moment method, the level set method, and the computational methods for interface problems in high frequency waves. These approaches are all based on high frequency asymptotic limits.
متن کاملScattering of elastic waves in heterogeneous media with local isotropy.
The scattering of elastic waves in heterogeneous media is discussed. Explicit expressions are derived for the attenuation of longitudinal and transverse elastic waves in terms of the statistics of the density and Lamé parameter fluctuations. The derivation is based upon diagrammatic methods with the problem posed in terms of the Dyson equation. The Dyson equation is solved for the mean field re...
متن کاملA model for enhanced fluid percolation in porous media by application of low-frequency elastic waves
[1] Numerous observations and laboratory experiments suggest that elastic vibrations can significantly enhance transport of nonaqueous phase liquids (NAPLs) in porous media. Our analyses suggest that in the low-frequency range, capillary forces and nonlinear rheology of the fluid may be predominant mechanisms of vibratory stimulation. Consequently, a model of these mechanisms is built to explai...
متن کاملA Finite Volume Evolution Galerkin Scheme for Acoustic Waves in Heterogeneous Media
In this paper, we present a numerical scheme for the propagation of acoustic waves in a heterogeneous medium in the context of the finite volume evolution Galerkin (FVEG) method (M. Lukáčová-Medvid’ová et al. J. Comput. Phys., 183:533–562, 2002). As a mathematical model we consider a wave equation system with space dependent wave-speed and impedance, which is used to study the wave propagation ...
