Lattice‐Boltzmann simulation of two‐phase flow in porous media
TL;DR: In this paper, a lattice Boltzmann (LB) approach was used to simulate two-fluid-phase flow at the pore scale using a Shannon-Chen model.

Measuring techniques in gas–liquid and gas–liquid–solid reactors
TL;DR: In this paper, an overview of multiphase flow metering techniques for gas/liquid analysis can be found, including nonintrusive techniques that deliver global, cross-section-averaged or local data.

Porous Media: Fluid Transport and Pore Structure
TL;DR: In this paper, the authors examined the relationship between transport properties and pore structure of porous material and presented models of pore structures with a discussion of how such models can be used to predict the transport properties of porous media.

Principles of Nuclear Magnetic Resonance Microscopy
TL;DR: In this paper, the authors introduce the principles of imaging for nuclear magnetic resonance and describe the influence of magnetic field gradients on the magnetic field. But they do not discuss the application of magnetic resonance in biology and minerals science.
Fluid Dynamics for Physicists
TL;DR: In this article, the authors provide an accessible and comprehensive account of the subject, emphasising throughout the fundamental physical principles, and stressing the connections with other branches of physics, including non-Newtonian fluids and the propagation and attenuation of sound in gases.

Determination and Characterization of the Structure of a Pore Space from 3D Volume Images
TL;DR: In this paper, a variant of morphological thinning is used to partition the void space into a discrete and well-defined collection of individual pore necks, which are defined by criteria which are well established in the literature.
