Experimental study on seepage characteristics of rough fracture of limestone under loading-unloading of confining and osmotic pressures

open access: yesYantu gongcheng xuebao, 2023
The influences of the roughness of fracture surface and the loading-unloading environment on seepage characteristics of fracture cannot be ignored. To study the influences of the fracture surface with different joint roughness coefficients (JRC) and ...

Hydrothermal coupling in a self-affine rough fracture [PDF]

open access: yesPhysical Review E, 2010
The influence of the multiscale fracture roughness on the heat exchange when a cold fluid enters a fractured hot solid is studied numerically on the basis of the Stokes equation and in the limit of both hydrolubrication and thermolubrication. The geometrical complexity of the fracture aperture is modeled by small self-affine perturbations added to a ...

Visualization experimental investigation into the dissolution processes in rough fracture under gravity conditions

open access: yesShuiwen dizhi gongcheng dizhi, 2023
Dissolution of rock fractures is common in natural processes and engineering practices, in which gravity plays an important role. Visual observation technology is a key means to study the mechanism of dissolution in rough fractures.

Modeling of Two-Phase Flow in Rough-Walled Fracture Using Level Set Method

open access: yesGeofluids, 2017
To describe accurately the flow characteristic of fracture scale displacements of immiscible fluids, an incompressible two-phase (crude oil and water) flow model incorporating interfacial forces and nonzero contact angles is developed.

A Novel Approach to Investigating Transport of Lost Circulation Materials in Rough Fracture

open access: yesEnergies, 2018
The drilling fluid loss or lost circulation via fractures is one of the critical engineering problems in the development of deep oil and gas resources. The conventional treatment is to introduce granular lost circulation material (LCM) into the drilling ...

Numerical Simulation for Rock Fracture Viscoelastic Creep under Dry Conditions

open access: yesGeofluids, 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.

A simple proof of distance bounds for Gaussian rough paths [PDF]

open access: yes, 2013
We derive explicit distance bounds for Stratonovich iterated integrals along two Gaussian processes (also known as signatures of Gaussian rough paths) based on the regularity assumption of their covariance functions.
