A Unified Theory for Chaotic Mixing in Porous Media: from Pore Networks to Granular Systems
Daniel Lester, Joris Heyman, Yves Meheust +1
Recent studies have revealed the central role of chaotic stretching and folding at the pore scale in controlling mixing within porous media, whether the solid phase is discrete (as…
Packing and voids in electro-rheological structures of polarized clay particles
K. P. S. Parmar, Y. Meheust, J. O. Fossum +2
Oil suspensions of fluorohectorite clay particles exhibit a dramatic meso-structural ordering when submitted to a strong electric field. This is due to dipolar interaction between…
Inferring orientation distributions in anisotropic powders of nano-layered crystallites from a single two-dimensional WAXS image
Yves Meheust, Kenneth Dahl Knudsen, Jon Otto Fossum
The wide-angle scattering of X-rays by anisotropic powders of nano-layered crystallites (nano-stacks) is addressed. Assuming that the orientation distribution probability function…
Using synchrotron X-ray scattering to study the diffusion of water in a weakly-hydrated clay sample
Y. Meheust, B. Sandnes, G. Lovoll +6
We study the diffusion of water in weakly-hydrated samples of the smectite clay Na-fluorohectorite. The quasi one-dimensional samples are dry compounds of nano-layered particles co…
Growth activity during fingering in a porous Hele Shaw cell
Grunde Lovoll, Yves Meheust, Renaud Toussaint +2
We present in this paper an experimental study of the invasion activity during unstable drainage in a 2D random porous medium, when the (wetting) displaced fluid has a high viscosi…
