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 …

The nonlinear flow behavior in a single rock fracture (SRF) has been studied for decades.
However, the existing models to link fracture geometries and nonlinear flow behavior are …

A study on the percolation characteristics of single-phase flow in rough fractures at high
rates representing hydraulic fracturing conditions is presented. Two-dimensional transparent …

This paper presents qualitative and quantitative analysis of single and multiphase flow in a
single fracture based on experimental results and demonstrates relationships between the …

Hydraulic fracturing treatment in rocks creates surfaces that are not smooth but rough in
general. Accurate characterization of surface roughness is necessary to relate fracture …

The influence of roughness, aperture and asperity irregularity on fluid flow regimes in rough
rock fractures was investigated by performing coupled triaxial water flow tests and fluid …

To study the relationships between the friction factor f and the flow type in a single rough
fracture, the formulae of f for both unconfined and confined flows are deduced based on …

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 …

Nonlinear flow behavior of fluids through three-dimensional (3D) discrete fracture networks
(DFNs) considering effects of fracture number, surface roughness and fracture aperture was …

A single fracture is the basic unit of fracture medium, and the roughness of the fracture
surface is an important factor influencing hydraulic characteristics of the flow in bedrock …
