Critical point network for drainage between rough surfaces [PDF]
, 2007 In this paper, we present a network method for computing two-phase flows between two rough surfaces with significant contact areas. Low-capillary number drainage is investigated here since one-phase flows have been previously investigated in other ...

Interfacial fracture toughness of composite concrete beams [PDF]
, 2019 A test for measuring the interfacial fracture toughness of a bi-material interface, essentially for concrete overlaid pavements was developed. The measured interfacial fracture toughness of steel fibre-reinforced, roller-compacted, polymer modified ...

Experimental Study of Fracturing Fluid Retention in Rough Fractures [PDF]
Geofluids, 2019 Multistage hydraulic fracturing is a key technology for developing tight reservoirs. Field data indicate that a small fraction of the injected water can be recovered during flowback. Fractures play an important role in the retention of fracturing fluid, but the mechanisms and rules remain uncertain.

Fluid Flow Behavior of Sheared Rough Fractures Subjected to Different Stress State
Crystals, 2021 The hydraulic properties of fractures are greatly affected by the stress. Knowing the fluid flow behavior of fractures is of great importance to underground engineering construction and environmental safety. The main purpose of this paper is to study the

Effects of fracture aperture and roughness on hydraulic and mechanical properties of rocks : implication of seismic characterization of fractured reservoirs [PDF]
, 2005 Roughness and aperture are two important characteristic parameters controlling fluid flow in natural joints and fractures. It has been demonstrated by many authors that knowledge of roughness does not directly lead to that of aperture, and aperture ...

Quasi-static cracks and minimal energy surfaces [PDF]
, 1998 We compare the roughness of minimal energy(ME) surfaces and scalar ``quasi-static'' fracture surfaces(SQF). Two dimensional ME and SQF surfaces have the same roughness scaling, w sim L^zeta (L is system size) with zeta = 2/3.

Effect of fracture roughness on permeability coefficient under uniaxial compression
工程科学学报, 2021 The surface roughness of natural rock-fractures is an important factor affecting the fractured rock mass flow characteristics and further complicating the flow process in the natural fractures.
