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…
Influence of shear stress applied during flow stoppage and rest period on the mechanical properties of thixotropic suspensions
Guillaume Ovarlez, Xavier Chateau
We study the solid mechanical properties of several thixotropic suspensions as a function of the shear stress history applied during their flow stoppage and their aging in their so…
Yield stress and elastic modulus of suspensions of noncolloidal particles in yield stress fluids
Fabien Mahaut, Xavier Chateau, Philippe Coussot +1
We study experimentally the behavior of isotropic suspensions of noncolloidal particles in yield stress fluids. This problem has been poorly studied in the literature, and only on…
Shear thickening of cornstarch suspensions as a re-entrant jamming transition
Abdoulaye Fall, N. Huang, F. Bertrand +2
We study the rheology of cornstarch suspensions, a dense system of non-Brownian particles that exhibits shear thickening, i.e. a viscosity that increases with increasing shear rate…
Flow of wet granular materials
N. Huang, G. Ovarlez, F. Bertrand +3
The transition from frictional to lubricated flow of a dense suspension of non-Brownian particles is studied. The pertinent parameter characterizing this transition is the Leighton…
A giant overshoot effect in the Janssen granular column
G. Ovarlez, C. Fond, E. Clément
We present new experimental results on the mechanical behavior of static granular assemblies confined in a vertical column. Our measurements confirm, for the first time, the univer…
