Fluid transport in porous materials is commonly studied in geological samples (soil, sediments, etc.) or idealized systems, but the fluid flow through compacted granular materials, consisting of substantially strained granules, remains relatively unexplored. As a step toward filling this gap, we study a model of liquid transport in packings of deformable elastic shells using finite-element and lattice-Boltzmann methods. We find that the fluid flow abruptly vanishes as the porosity of the…

Theory and simulation of open systems out of equilibrium.
The theoretical model of Bergmann and Lebowitz for open systems out of equilibrium is considered and its principles are translated in the adaptive resolution simulation molecular dynamics technique to find excellent agreement of the stationary responses with the results from the simulation of a larger locally forced closed system.
Open Systems out of Equilibrium: Theory and Simulation
We consider the theoretical model of Bergmann and Lebowitz for open systems out of equilibrium and translate its principles in the adaptive resolution molecular dynamics technique (AdResS). We


Impact of geometrical properties on permeability and fluid phase distribution in porous media
To predict fluid phase distribution in porous media, the effect of geometric properties on flow processes must be understood. In this study, we analyze the effect of volume, surface, curvature and

An alternative method is proposed, which enables one to calculate T directly from the fluid velocity field, without the need of determining streamlines, which greatly simplifies determination of tortuosity in complex geometries, including those found in experiments or three-dimensional computer models.
Temporal evolution of pore geometry, fluid flow, and solute transport resulting from colloid deposition
Deposition of colloidal particles is one of many processes that lead to the evolution of the structure of natural porous media in groundwater aquifers, oil reservoirs, and sediment beds.
Viscoinertial regime of immersed granular flows.
It is shown that, for a broad range of system parameters (shear rate, confining stress, fluid viscosity, and relative fluid-grain density), the frictional strength and packing fraction can be described by a modified inertial number incorporating the fluid effect.
Flow phenomena in rocks : from continuum models to fractals, percolation, cellular automata, and simulated annealing
In this paper, theoretical and experimental approaches to flow, hydrodynamic dispersion, and miscible and immiscible displacement processes in reservoir rocks are reviewed and discussed. Both
Scaling and critical behavior of lattice and continuum porous media with different connectivity configurations
Abstract Determination of the connectivity and conductivity of porous media is of great importance in evaluation of fluid transport in different systems including petroleum formations, ground water
Tortuosity-porosity relation in porous media flow.
It is demonstrated that the finite-size, slow relaxation and discretization errors, which were ignored in previous studies, may cause significant underestimation of tortuosity.
Pore-scale analysis of permeability reduction resulting from colloid deposition: COLLOID DEPOSITION REDUCES PERMEABILITY
High-energy, synchrotron-based x-ray difference micro-tomography (XDMT) was combined with lattice Boltzmann simulations to assess changes in pore-scale flow patterns and bulk permeability resulting
Percolation Theory Generates a Physically Based Description of Tortuosity in Saturated and Unsaturated Porous Media
Tortuosity is a property of porous media that is invoked and used in the literature on hydrology, soil science, physics, and engineering. It has been defined in a variety of ways, one of which is a
Computer simulation of the effect of deformation on the morphology and flow properties of porous media.
We report on the results of extensive computer simulation of the effect of deformation on the morphology of a porous medium and its fluid flow properties. The porous medium is represented by packings
