The lattice Boltzmann method and pore network model are two types of the most popular pore-scale fluid flow simulation methods. As a direct numerical method, simulates directly in realistic porous structures, characterized by high computational accuracy but low efficiency. On contrary, simplified regular networks real media, which is more computationally efficient, fails to capture detailed str...

The pore size of biopolymer networks governs their mechanical properties and strongly impacts the behavior of embedded cells. Confocal reflection microscopy and second harmonic generation microscopy are widely used to image biopolymer networks; however, both techniques fail to resolve vertically oriented fibers. Here, we describe how such directionally biased data can be used to estimate the ne...

A pore-scale model is developed to simulate mass transfer between two fluid phases in a porous medium. The approach uses a network description of the pore space and builds on explicit tracking of the fluid-fluid interfaces in the pore network. Mass transfer is computed as local mass fluxes across each interface, and transport equations are solved in the pore network by a characteristic method. ...

First, we discuss network models and techniques for determining the pore-scale properties and characterisWhile network models of porous materials have traditionally been tics; second, we describe the regular and random porous constructed using regular or disordered lattices, recent developments allow the direct modeling of more realistic structures such as sphere media systems used to validate ...

Pore-scale network modeling can predict multiphase flow properties with arbitrary wetting conditions if the network represents the geology of the sample accurately. Such pore-scale modeling uses topologically disordered networks that realistically represent the pore structure. To generate the network it is first necessary to have a three-dimensional voxel-based pore-space representation that is...

In this study, a recently developed pore network drying model (Metzger et al. 2007a), which accounts for liquid viscosity, is applied to three dimensions for the first time. Isothermal convective drying is simulated for a cubic network (25×25×50) with pore throats of mono-modal radius distribution. The role of liquid viscosity is assessed by comparison with non-viscous drying of the same networ...

Continuous filtration of fine particles involves filter cake formation and removal of surface moisture by drawing air through the pore structure network. Conventional network theory can be use to study the phenomena of flow through a porous structure by treating the pores as discrete volumes and connecting these with pore throats as resistances of zero volume. In this regard, analysis of the po...
