Influence of fracture scale heterogeneity on the flow properties of three‐dimensional discrete fracture networks (DFN)
While permeability scaling of fractured media has been so far studied independently at the
fracture‐and network‐scales, we propose a numerical analysis of the combined effect of …

2D and 3D roughness characterization
E Magsipoc, Q Zhao, G Grasselli - 2020 - Springer
The quantification of surface roughness for the purpose of linking its effect to mechanical
and hydrodynamic behavior has taken many different forms. In this paper, we present a …

Pore-scale numerical investigation of the impacts of surface roughness: Upscaling of reaction rates in rough fractures
The roughness of solid surfaces influences mineral dissolution rates by affecting flow and
transport in the near-surface regions and by increasing the surface area available for …

Emergence of anomalous transport in stressed rough fractures
We report the emergence of anomalous (non-Fickian) transport through a rough-walled
fracture as a result of increasing normal stress on the fracture. We show that the origin of this …

The effect of fracturing on permeability in carbonate reservoir rocks
Hydrocarbon flow rates from tight carbonate reservoirs often depend on the distribution and
properties of fractures throughout the reservoir interval. Hence, quantification of fracture …

Fluid flow through rough fractures in rocks. II: A new matching model for rough rock fractures
An understanding of fluid flow through natural fractures in rocks is important in many areas,
such as in the hydrocarbon and water industries, and in the safe design of disposal sites for …

Scale and size effects on fluid flow through self-affine rough fractures
A permeability estimation of a single rough fracture remains challenging and has attracted
broad attention because of its fundamental importance. This study examines the effects of …

[HTML][HTML] Numerical modeling of the effects of roughness on flow and eddy formation in fractures
The effect of roughness on flow in fractures was investigated using lattice Boltzmann method
(LBM). Simulations were conducted for both statistically generated hypothetical fractures …

Size effect on aperture and permeability of a fracture as estimated in large synthetic fractures
Synthetic fractures of from 0.2 to 12.8 m in size were created on a computer by a new
spectral method to reproduce the ratio of the power spectral density of the initial aperture …
