Hydrothermal coupling in a rough fracture
, 2006 Heat exchange during laminar flow is studied at the fracture scale on the basis of the Stokes equation. We used a synthetic aperture model (a self-affine model) that has been shown to be a realistic geometrical description of the fracture morphology. We developed a numerical modelling using a finite difference scheme of the hydrodynamic flow and its ...

Flow enhancement of a rough fracture [PDF]
Geophysical Research Letters, 2000 We study experimentally and numerically the permeability of a rough fracture at laboratory scale when viscous forces are dominating (low Reynolds number). The experimental setup includes a granite fracture surface (10 × 10 cm²) opened in mode I. It allows a continuous opening of the fracture parallel to its mean plane.

Impact of the fracture contact area on macro-dispersion in single rough fractures [PDF]
Comptes Rendus. Mécanique, 2021 In the scientific literature, the study of the impact of the fracture contact area on macro-dispersion in single rough fractures is still an open question. In this work, we study numerically the combined effects of the fracture roughness and the fracture contact area on the non-Fickian transport in single rough fractures.

Energies, 2022 The surface morphology of fractures formed by hydraulic fracturing is usually rough. The roughness of the fracture surface is the main reason the actual fracture conductivity deviates from the ideal flat plate model result.

Experimental and numerical studies on non-Darcian flow in single rough-walled rock fracture
Yantu gongcheng xuebao, 2023 A series of rough-walled rock fracture specimens with specific surface roughnesses are made by using the three- dimensional carving. After that, the self-designed apparatus which can quantitatively change the aperture of single rock fracture is adopted ...

Synthetic rough fractures in rocks [PDF]
Journal of Geophysical Research: Solid Earth, 1998 Natural fractures serve a very important function in the transport of fluid through rocks, as well as in the flow of electrical charge and heat. The creation of numerically synthesized fractures can aid the study of the physical processes connected with fractures. Synthetic fracture is the term used to describe fractures that are created numerically in

Lattice Boltzmann simulation of solute transport in a single rough fracture
Water Science and Engineering, 2014 In this study, the lattice Boltzmann method (LBM) was used to simulate the solute transport in a single rough fracture. The self-affine rough fracture wall was generated with the successive random addition method.

Frontiers in Physics, 2022 The water-sediment two-phase flow in the rough fracture is one of the main causes of water-sediment inrush. In this study, numerical simulation models of the water-sediment two-phase flow in the smooth and rough fractures were established by ANSYS Fluent

How Material Heterogeneity Creates Rough Fractures
Physical Review Letters, 2022 Fractures are a critical process in how materials wear, weaken, and fail whose unpredictable behavior can have dire consequences. While the behavior of smooth cracks in ideal materials is well understood, it is assumed that for real, heterogeneous systems, fracture propagation is complex, generating rough fracture surfaces that are highly sensitive to ...

Fractal model and Lattice Boltzmann Method for Characterization of Non-Darcy Flow in Rough Fractures. [PDF]
, 2017 The irregular morphology of single rock fracture significantly influences subsurface fluid flow and gives rise to a complex and unsteady flow state that typically cannot be appropriately described using simple laws.
