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 …

Natural tight reservoirs are networks with high connectivity but low porosity, in which fractal
behaviors have been widely observed and proven to affect the transport property …

In this study, we performed multitracer laboratory bench-scale experiments and pore-scale
simulations in different homogeneous saturated porous media (ie, different grain sizes) with …

An accurate quantitative description of the diffusion coefficient in a porous medium is
essential for predictive transport modeling. Well-established relations, such as proposed by …

The mass transport properties of bulk random sphere packings depend primarily on the bed
(external) porosity ɛ, but also on the packing microstructure. We investigate the influence of …

Tortuosity quantitatively reflects the complexity of porous media. For the diffusion process in
porous media, diffusive tortuosity is inevitably an important research topic. A simulation …

In reservoir engineering, hydrodynamic properties can be estimated from downhole
electrical data using heuristic models (eg, Archie and Kozeny-Carman's equations) relating …

Bone tissue is a hierarchically structured material composed at the nanoscale by an organic
matrix of collagen type I, apatite mineral and water. We considered an idealized 3D …

The tortuosity of porous solids has been widely used as a basic concept in understanding
the fluid flow capacity of these media. Starting from a geometric expression of the tortuosity …

Capillary force and boundary layer effect are the main causes of non-Darcy flow in tight oil
reservoir. This paper proposes a non-Darcy flow dynamics characterization method for low …
