Numerical Simulation for Rock Fracture Viscoelastic Creep under Dry Conditions

Geofluids, 2020
In many rock engineering projects such as hydrocarbon extraction and geothermal energy utilization, the hydraulic and mechanical behavior of rock fractures significantly affects the safety and profitability of the project.

The Effect of Roughness on the Nonlinear Flow in a Single Fracture with Sudden Aperture Change

Lithosphere, 2022
Abrupt changes in aperture (sudden expansion and contraction) are commonly seen in naturally occurred or artificial single fractures. The relevant research mainly focuses on the changes in fluid properties caused by the sudden expansion of the aperture ...

The Effect of Fracture Roughness on the Onset of Nonlinear Flow [PDF]

Water Resources Research, 2020
AbstractIn fractures where surface fluctuations are large compared to their aperture (narrow fractures), the flow is forced to move in tortuous paths that produce additional viscous friction and are subject to inertia effects. We consider the relation between the magnitude of surface roughness and the onset of inertial effects in the pressure driving ...

Experimental study of convective heat transfer characteristics of fractures with different morphologies based on fractal theory

Case Studies in Thermal Engineering, 2021
In the Enhanced Geothermal System (EGS), the flow state of the fracture of the thermal reservoir (granite) is important for heat transfer. In this paper, the effects of reservoir temperature, flow rate and fracture shape on the thermal convection that ...

Permeability Estimates of Self-Affine Fracture Faults Based on Generalization of the Bottle Neck Concept [PDF]

, 2010
We propose a method for calculating the effective permeability of two-dimensional self-affine permeability fields based on generalizing the one-dimensional concept of a bottleneck.

Disentangling Scaling Properties in Anisotropic Fracture

, 2005
Structure functions of rough fracture surfaces in isotropic materials exhibit complicated scaling properties due to the broken isotropy in the fracture plane generated by a preferred propagation direction.

Numerical Modeling of Fluid Flowing Properties through Porous Media with Single Rough Fractures

Geofluids, 2021
Due to the existence of pores in the fracture surface, the permeability of pore-fracture media is more complicated, and its permeability law and mechanism are worthy of an in-depth study.
