TLDR
The results of the diffusion experiments indicate that there is a close relationship between total porosity and the effective diffusion coefficient of a rock (analogous to Archie's Law), and the tortousity factor can be expressed as a function oftotal porosity.About:

Tortuosity in Porous Media: A Critical Review
TL;DR: The concept of tortuosity is used to characterize the structure of porous media, to estimate their electrical and hydraulic conductivity, and to study the travel time and length for tracer dispersion as mentioned in this paper.

Water-induced variations in mechanical properties of clay-bearing rocks
TL;DR: In this paper, the results obtained from laboratory tests carried out on different types of clay-bearing rock collected from various parts of Turkey, to quantify the effects of water content on mechanical properties of the rocks, and to develop a method for estimating the rock strength and deformability at any water content based on physical properties.

Numerical simulation of convective heat transfer between air flow and ceramic foams to optimise volumetric solar air receiver performances
TL;DR: In this paper, the authors designed an approach to compute the local convective heat transfer coefficient between the air flow and a porous ceramic foam, which is used to achieve high performance in solar heat recovery systems.

The mathematics of diffusion
TL;DR: Though it incorporates much new material, this new edition preserves the general character of the book in providing a collection of solutions of the equations of diffusion and describing how these solutions may be obtained.

The electrical resistivity log as an aid in determining some reservoir characteristics
TL;DR: The usefulness of the electrical resistivity log in determining reservoir characteristics is governed largely by: (1) the accuracy with which the true resistivity of the formation can be determined; (2) the scope of detailed data concerning the relation of resistivity measurements to formation characteristics; (3) the available information concerning the conductivity of connate or formation waters; and (4) the extent of geologic knowledge regarding probable changes in facies within given horizons, both vertically and laterally, particularly in relation to the resultant effect on the electrical properties of the reservoir as mentioned in this paper.

Percolation and Conduction
TL;DR: In this article, an extension of percolation theory to treat transport is described, and a general expression for the conductance of such networks is derived, which relates to the spin-stiffness coefficient of dilute ferromagnet.

Mechanisms of Slow Sorption of Organic Chemicals to Natural Particles
TL;DR: The use of equilibrium expressions for sorption to natural particles in fate and transport models is often invalid due to slow kinetics and diffusion limitations appear to play a major role.

An introduction to percolation theory
TL;DR: Percolation theory, the theory of the properties of classical particles interacting with a random medium, is of wide applicability and provides a simple picture exhibiting critical behaviour, the features of which are well understood and amenable to detailed calculation.
