TL;DR: In this article, a modified Local Cubic Law (MLCL) is proposed for predicting the hydraulic properties of rough fractures, which takes into account local tortuosity and roughness, and works across a low range of local Reynolds Numbers.

TL;DR: In this article, two-dimensional Navier-Stokes flow and transport simulations are conducted for a 15-cm long fracture mapped via X-ray computed tomography, where the actual fracture with irregular aperture, truncated fracture with further thinning of other large aperture areas, and a fracture with uniform vertical aperture equal to actual fracture's mean aperture, are subjected to the same pressure gradient.

TL;DR: In this paper, the authors proposed an improved method for fracture measurement that consists of characterizing the blurring as a point-spread function (PSF), and using it, in combination with a calibration for the CT number for void space, in an iterative procedure to reconstruct the fracture and material configuration; they call this the inverse PSF (IPSF) method.

TL;DR: In this paper, two-dimensional flow and transport simulations are conducted for a 15 cm-long fracture mapped via X-ray computed tomography, and the simulations consider either Navier-Stokes equation based flow or Stokes equation (SE) based flow and are run for opposing directions.
