Shear-thickening in presence of adhesive contact forces: the singularity of cornstarch
Anais Gauthier, Guillaume Ovarlez, Annie Colin
A number of dense particle suspensions experience a dramatic increase in viscosity with the shear stress, up to a solid-like response. This shear-thickening process is understood a…
Emulsion Destabilization by Squeeze Flow
Riande I Dekker, Antoine Deblais, Krassimir P Velikov +5
There is a large debate on the destabilization mechanism of emulsions. We present a simple technique using mechanical compression to destabilize oil-in-water emulsions. Upon compre…
A new pressure sensor array for local normal stress measurement in complex fluids
Gauthier Anaïs, Pruvost Mickaël, Gamache Olivier +1
A new pressure sensor array, positioned on the bottom plate of a standard torsional rheometer is presented. It is built from a unique piezo-capacitive polymeric foam, and consists…
Elastic instability in stratified core annular flow
Oriane Bonhomme, Alexander Morozov, Jacques Leng +1
We study experimentally the interfacial instability between a layer of dilute polymer solution and water flowing in a thin capillary. The use of microfluidic devices allows us to o…
Wall slip, shear banding, and instability in the flow of a triblock copolymer micellar solution
S. Manneville, A. Colin, G. Waton +1
The shear flow of a triblock copolymer micellar solution (PEO--PPO--PEO Pluronic P84 in brine) is investigated using simultaneous rheological and velocity profile measurements in t…
Extracting the hydrodynamic resistance of droplets from their behavior in microchannel networks
Vincent Labrot, Michael Schindler, Pierre Guillot +2
The overall traffic of droplets in a network of microfluidic channels is strongly influenced by the liquid properties of the moving droplets. In particular, the effective hydrodyna…
