Water inrush is one of the most dangerous disasters in coal mining. Due to the large-scale
mining and complicated hydrogeological conditions, thousands of deaths and huge …

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 …

This study experimentally investigated the nonlinear flow characteristics at low Reynolds
number through rough-walled fractures subjected to a wide range of confining pressures …

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 …

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 …

Single phase water flow experiments were performed on seven tightly-closed, rough model
fractures. Each model has mirror-image transparent upper and opaque lower walls …

The flow behavior in smooth and artificial rough fractures is experimentally investigated. The
piezometric head is measured at several positions to determine experimentally the head …

This study experimentally and numerically investigated the influence of the inertial effect of
fluid flow on the non-Darcy coefficient (β). The results showed that the non-Darcy coefficient …

The friction factor is an important dimensionless parameter for fluid flow through rock
fractures that relates pressure head loss to average flow velocity; it can be affected by both …

Seepage in rock fractures is influenced by the geometry of the contact area. A parallel model
with two circular cylindrical contact areas is studied by numerical simulation. The variation of …
