Homogenization of reaction-diffusion equations in fractured porous media

open access: yesElectronic Journal of Differential Equations, 2015
The article studies the homogenization of reaction-diffusion equations with large reaction terms in a multi-scale porous medium. We assume that the fractures and pores are equidistributed and that the coefficients of the equations are periodic.

An improved wave equation of fractured-porous media for predicting reservoir permeability

open access: yesFrontiers in Earth Science, 2023
The wave characteristics of fractured-porous media can be utilized for permeability identification; however, further research is necessary to enhance the accuracy of this identification. A novel wave equation for fractured-porous media is formulated, and

Delayed Fracture in Porous Media [PDF]

open access: yesPhysical Review Letters, 2005
The fracture of porous media subjected to a constant load is studied. Contrary to homogeneous solids in which fracture usually happens instantaneously at a well-defined breaking strength, the fracture of a porous medium can occur with a delay, allowing us to quantify the average lifetime of the unbroken material.

Capillary Fracturing in Granular Media [PDF]

open access: yesPhysical Review Letters, 2012
We study the displacement of immiscible fluids in deformable, noncohesive granular media. Experimentally, we inject air into a thin bed of water-saturated glass beads and observe the invasion morphology. The control parameters are the injection rate, the bead size, and the confining stress.

A New Multicontinuum Model for Advection-Diffusion Process of Single-Phase Nonlinear Flow in a Multiscale Fractured Porous Media

open access: yesJournal of Applied Mathematics, 2022
Fractured porous media modeling and simulation has seen significant development in the past decade but still pose a great challenge and difficulty due to the multiscale nature of fractures, domain heterogeneity, and the nonlinear flow fields due to the ...
