TL;DR: A more generalized spontaneous imbibitions model is developed by considering the different sizes and shapes of pores, the tortuosity of imbibition streamlines in random porous media, and the initial wetting-phase saturation and test results show that the generalized model can be used to characterize the spontaneous imbIBition behavior of many different porous media.

TL;DR: Based on the fractal character of porous media, a full analytical model for characterizing spontaneous imbibition of wetting liquid vertically into gas-saturated porous media has been derived including gravity over the entire imbibulation process time frame as discussed by the authors.

TL;DR: A review of the electrical conductivity models developed using fractal, percolation and effective medium theories is presented in this paper, where the results obtained by comparing experiential and theoretical models with experiments/simulations are analyzed.

TL;DR: In this article, the authors measured the fractal dimension of fracture network in porous media under drying process by the improved box-counting technique, and fractal dimensions were respectively related to drying time, average aperture, moisture content and fracture porosity.

TL;DR: In this article, a theoretical electrical conductivity equation is derived based on the fractal characteristics of porous media, which is expressed in terms of the tortuosity fractal dimension (DT), the pore fractal dimensions (Df), and the electrical conductivities of pore liquid.
