Journal ArticleDOI
Evidence for three-dimensional unstable flows in shear-banding wormlike micelles.
TL;DR: An experimental study of the shear-banding phenomenon in the concentrated wormlike micellar system CTAB at 20wt.% in D2O confirms the studies performed previously and investigates possible causes for three-dimensional instability.
Journal ArticleDOI
Spatial cooperativity in soft glassy flows
TL;DR: This work uses a microfluidic velocimetry technique to characterize the flow of thin layers of concentrated emulsions, confined in gaps of different thicknesses by surfaces of different roughnesses, and shows that a rather simple non-local flow rule can account for all the velocity profiles.
Journal ArticleDOI
Kinetic theory of plastic flow in soft glassy materials.
TL;DR: A kinetic model for the elastoplastic dynamics of a jammed material is proposed, which takes the form of a nonlocal--Boltzmann-like--kinetic equation for the stress distribution function, predicting finite size effects in the flow behavior, as well as the absence of an intrinsic local flow curve.
Journal ArticleDOI
Stability of a Jet in Confined Pressure-Driven Biphasic Flows at Low Reynolds Numbers
TL;DR: This work experimentally evidence a transition between situations where the flow takes the form of a jet and regimes where drops are produced, within a simple linear analysis using lubrication theory for flows at low Reynolds number, and reaches remarkable agreement with the data.
Journal ArticleDOI
Stability of parallel flows in a microchannel after a T junction.
Pierre Guillot,Annie Colin +1 more
TL;DR: It was shown that droplets are formed through a blocking-pinching mechanism ruled by flow rate conservation and transition from droplet regime to parallel flows cannot be described in terms of capillary numbers.
