Predicting Plasticity in Two-Dimensional Foam Channel Flow Around an Obstacle
Alexandre Stepanetz, Bahaa Mazloum, Benjamin Dollet +1
We study the prediction of plastic activity in the confined channel flow of two-dimensional amor- phous soft particles around a circular obstacle. Using datasets generated with a p…
Long distance attraction between particles in a soap film
Youna Louyer, Megan Delens, Nicolas Vandewalle +3
Millimeter-sized particles trapped at the surface of a liquid bath attract each other through the deformation of the liquid-air interface, a phenomenon known as "the Cheerios effec…
Channel Flow Around an Obstacle in a Two-Dimensional Soft Particles
Bahaa Mazloum, Alexandre Stepanetz, Benjamin Dollet +1
We numerically study confined channel flow around an obstacle using a two-dimensional soft par- ticle model, inspired by experiments performed in the same geometry. We systematical…
Exponential Stress Relaxation Driven by Elementary Plastic Events in Non-Ageing Liquid Foams
F. Schott, B. Dollet, C. M. Schlepütz +5
Liquid foams are archetypal athermal amorphous solids whose elasticity arises from the jamming of densely packed bubbles. We investigate the stress relaxation of non-ageing liquid…
Tunable effective diffusion of CO2 in aqueous foam
Cécile Aprili, Gwennou Coupier, Ãlise Lorenceau +1
Aqueous foams are solid materials composed of gases and liquids, exhibiting a large gas/liquid surface area and enabling dynamic exchanges between their fluid components. The struc…
Multiscale stress dynamics in sheared liquid foams revealed by tomo-rheoscopy
Florian Schott, Benjamin Dollet, Stéphane Santucci +5
Rheology aims at quantifying the response of materials to mechanical forcing. However, standard rheometers provide only global macroscopic quantities, such as viscoelastic moduli.…
