Biphasic flow: structure and upscaling, consequences on macroscopic transport properties
Renaud Toussaint, Knut Jørgen Måløy, Yves Méheust +4
In disordered porous media, two-phase flow of immiscible fluids (biphasic flow) is organized in patterns that sometimes exhibit fractal geometries over a range of length scales, de…
Local dynamics of a randomly pinned crack front during creep and forced propagation: An experimental study
Ken Tore Tallakstad, Renaud Toussaint, Stéphane Santucci +2
We have studied the propagation of a crack front along the heterogeneous weak plane of a transparent poly(methyl methacrylate) (PMMA) block using two different loading conditions:…
Hydraulic transmissivity and heat exchange efficiency of open fractures: a model based on lowpass filtered apertures
Amélie Neuville, Renaud Toussaint, Jean Schmittbuhl
Natural open joints in rocks commonly present multi-scale self-affine apertures. This geometrical complexity affects fluid transport and heat exchange between the flow- ing fluid a…
Fracture Roughness Scaling: a case study on planar cracks
Stéphane Santucci, Mélanie Grob, Alex Hansen +3
Using a multi-resolution technique, we analyze large in-plane fracture fronts moving slowly between two sintered Plexiglas plates. We find that the roughness of the front exhibits…
Characterization of Fault Roughness at Various Scales: Implications of Three-Dimensional High Resolution Topography Measurements
Thibault Candela, François Renard, Michel Bouchon +3
Accurate description of the topography of active faults surfaces represents an important geophysical issue because this topography is strongly related to the stress distribution al…
Variety of stylolites morphologies and statistical characterization of the amount of heterogeneities in the rock
Alexandre Brouste, François Renard, Jean-Pierre Gratier +1
The surface roughness of several stylolites in limestones was measured using high resolution laser profilometry. The 1D signals obtained were statistically analyzed to determine th…
