The solid-liquid transition in complex fluids
Reinhard Hohler, Sylvie Cohen-Addad, Vincent Labiausse
The yielding of foams, concentrated emulsions, pastes and other soft materials under applied strain is often characterized by measuring the complex shear modulus as a function of s…
Shear induced normal stress differences in aqueous foams
Vincent Labiausse, Reinhard Hohler, Sylvie Cohen-Addad
A finite simple shear deformation of an elastic solid induces unequal normal stresses. This nonlinear phenomenon, known as the Poynting effect, is governed by a universal relation…
A multiscale model for the slow viscoelastic response of liquid foams
Sebastien Vincent-Bonnieu, Reinhard Hohler, Sylvie Cohen-Addad
Using 2D numerical simulations as well as analytical modelling, we show how slow viscoelastic dynamics of aqueous foam are linked to coarsening induced intermittent bubble rearrang…
A high rate flow-focusing foam generator
Elise Lorenceau, Yann Yip Cheung Sang, Reinhard Hohler +1
We use a rigid axisymetric microfluidic flow focusing device to produce monodisperse bubbles, dispersed in a surfactant solution. The gas volume fraction of the dispersion collecte…
