TL;DR: In this article, a physical conceptual model has been developed for two-phase flow in unsaturated porous media according to the fractal characteristics of pore-scale geometrical structure of natural porous media and analytical expressions of relative permeabilities for wetting and nonwetting phases have been presented, which are the functions of wetting fluid saturation and porosity as well as fractal dimensions of the medium.

TL;DR: In this paper, the effects of the time-mean jet Reynolds number, temperature difference between the jet flow and the impinging surface, nozzle-to-target distance as well as the frequency on heat and mass transfer were examined.

TL;DR: In this article, a fractal dual-porosity model is developed to estimate the equivalent hydraulic properties of fractured porous media, where fractal tree-like network model is used to characterize the fracture system according to its fractal scaling laws and topological structures.

TL;DR: In this paper, a probability model is developed for radial flow in fractured porous media by fractal theory and Monte Carlo technique, which shows that the effective radial permeability of fracture systems is an explicit function of geometrical parameters of the well and the size distributions of fractures.

TL;DR: In this article, a new analytical model is presented and solved for gas diffusion in fuel cell porous media based on fractal geometry, and an expression for the effective gas diffusivity of multi-scale porous media is derived, expressed in terms of bulk diffusion, pore structure as well as the Knudsen number.
