Rock fractures are crucial conduits for fluid flow in fractured rock masses. Three-dimensional
(3D) discrete fracture network (DFN) modeling approach, which can explicitly characterize …

Dissolution and precipitation reactions are the primary mechanisms that occur when a rock
(ie, a mineral assemblage) is in contact with a fluid out of equilibrium. They play a critical …

This study investigates the impacts of surface roughness on the nonlinear fluid flow through
three-dimensional (3D) self-affine rock fractures, whose original surface roughness is …

The objective of this paper is to investigate the effects of wall surface roughness on fluid flow
through rock fractures. A wavelet analysis technique was developed to define a …

Transient pulse tests were performed on single rock fractures at different confining
pressures. A new data analysis method based on polynomial fitting was introduced to …

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 …

Abstract Three-dimensional (3D) fluid flow and thermal transport modeling in discrete
fracture networks (DFNs) is critical for geothermal energy recovery from enhanced …

Nonlinear flow in 3D rough-walled rock fractures is simulated by solving the Navier-Stokes
equations. The emphasis is on the impact of shear-caused aperture changes (variable …

Fracture networks play a more significant role in conducting fluid flow and solute transport in
fractured rock masses, comparing with that of the rock matrix. Accurate estimation of the …

This study explores how the topology-based measure of connectivity of a three-dimensional
discrete fracture network (DFN) can be used to predict flow channelization, a commonly …
