Rheology and microstructure of unsaturated granular materials: Experiments and simulations
M. Badetti, A. Fall, F. Chevoir +3
When dealing with unsaturated wet granular materials, a fundamental question is: what is the effect of capillary cohesion on the bulk flow and yield behavior? We inwestigate the de…
Water transfer and crack regimes in nano-colloidal gels
J Thiery, Stéphane Rodts, E Keita +5
Direct observations of the surface and shape of model nano-colloidal gels associated with measurements of the spatial distribution of water content during drying show that air star…
Phenomenology and physical origin of shear-localization and shear-banding in complex fluids
Guillaume Ovarlez, Stéphane Rodts, Xavier Chateau +1
We review and compare the phenomenological aspects and physical origin of shear-localization and shear-banding in various material types, namely emulsions, suspensions, colloids, g…
MRI investigation of granular interface rheology using a new cylinder shear apparatus
Pascal Moucheront, François Bertrand, Georg Koval +5
The rheology of granular materials near an interface is investigated through proton magnetic resonance imaging. A new cylinder shear apparatus has been inserted in the MRI device,…
Wide-gap Couette flows of dense emulsions: Local concentration measurements, and comparison between macroscopic and local constitutive law measurements through magnetic resonance imaging
Guillaume Ovarlez, Stéphane Rodts, Alexandre Ragouilliaux +3
Flows of dense emulsions show many complex features among which long range nonlocal effects pose a problem for macroscopic characterization. In order to get around this problem, we…
Local determination of the constitutive law of a dense suspension of non-colloidal particles through MRI
Guillaume Ovarlez, François Bertrand, Stéphane Rodts
We investigate the flowing behavior of dense suspensions of non-colloidal particles, by coupling macroscopic rheometric experiments and local velocity and concentration measurement…
