Double Porosity Models for Acoustics

2013
Double porosity models for acoustics in poroelastic media is derived from homogenization theory. The fluid dynamics on the microscopic level is governed by the the nonstationary Stokes systems for a slightly compressible viscous liquid. The liquid domain is a union of two independent systems of fractures and pores.

Double Porosity and Second Sound

2017
Up to this point in this book we have considered thermoelastic bodies with a multiple porosity structure assuming that the heat flux is governed by a Fourier law, i.e. the heat flux is determined directly by the temperature gradient. Materials technology is advancing very rapidly and it is likely that for many future applications a Fourier law may be ...

Modeling Transverse Imbibition in Double-Porosity Simulators

Proceedings of SPE California Regional Meeting, 1988
ABSTRACT Published imbibition experiments of an advancing fracture water level surrounding a single matrix block are simulated using various double porosity models. These double porosity formulations are inherently unable to represent transverse imbibition with an advancing water level in the fracture as they are based essentially on one

Waves in Double Porosity Elasticity

2017
Rayleigh waves and Love waves have long been used as an important tool in geophysical problems employing linear elasticity theory. Rayleigh waves are studied using the Berryman & Wang [? ] double porosity theory presented in section 2.2, by Dai et al. [? ]. Dai et al.

Consolidation behaviour of double-porosity clay using flexible wall permeameter

Proceedings of the Institution of Civil Engineers - Ground Improvement, 2019
Restoration of a site that has previously been prepared using dredged clay is a serious geotechnical challenge. Much of these clays exists as lumps suspended in slurry.

Pressure transients in a double‐porosity medium

Water Resources Research, 1992
Pressure transients associated with a constant‐rate pumping test in a double‐porosity (fissured or multilayered) reservoir may exhibit, in succession, several periods of characteristic log linear dependence on time. If the flow in the matrix blocks is primarily vertical then slope halving of the semilog gradient may be observed, but if the radial ...
