Difficulties encountered in describing fracture flow using classical fluid flow equations has
led to extensive studies of the roughness effect on fracture flow over the past 70 years …

Transition of fluid flow from the linear to the nonlinear regime has been confirmed in single
rock fractures when the Reynolds number (Re) exceeds some critical values, yet the …

Understanding the shear-induced evolution of aperture size is critical for controlling fracture
permeability in rock engineering projects. This study reports a robust procedure to evaluate …

Fluid flow tests were conducted on two crossed fracture models for which the geometries of
fracture segments and intersections were measured by utilizing a visualization technique …

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 …
