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.

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.

Three-dimensional double-rough-walled modeling of fluid flow through self-affine shear fractures
Journal of Rock Mechanics and Geotechnical Engineering, 2020 This study proposes a double-rough-walled fracture model to represent the natural geometries of rough fractures. The rough surface is generated using a modified successive random additions (SRA) algorithm and the aperture distribution during shearing is ...

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

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 ...

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

Fluid Flow Behavior of Sheared Rough Fractures Subjected to Different Stress State
Crystals, 2021 The hydraulic properties of fractures are greatly affected by the stress. Knowing the fluid flow behavior of fractures is of great importance to underground engineering construction and environmental safety. The main purpose of this paper is to study the

Experimental Study of Fracturing Fluid Retention in Rough Fractures [PDF]
Geofluids, 2019 Multistage hydraulic fracturing is a key technology for developing tight reservoirs. Field data indicate that a small fraction of the injected water can be recovered during flowback. Fractures play an important role in the retention of fracturing fluid, but the mechanisms and rules remain uncertain.
