Tunable effective diffusion of CO2 in aqueous foam
Cécile Aprili, Gwennou Coupier, Élise 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…
Buckling of lipidic ultrasound contrast agents under quasi-static load
Georges Chabouh, Benjamin van Elburg, Michel Versluis +3
Collapse of lipidic ultrasound contrast agents under high-frequency compressive load has been historically interpreted by the vanishing of surface tension. By contrast, buckling of…
Lift at low Reynolds number
Lionel Bureau, Gwennou Coupier, Thomas Salez
Lift forces are widespread in hydrodynamics. These are typically observed for big and fast objects, and are often associated with a combination of fluid inertia (i.e. large Reynold…
Rheology and structure of a suspension of deformable particles in plane Poiseuille flow
Vassanti Audemar, Thomas Podgorski, Gwennou Coupier
We present an experimental study of the rheology and structure of a confined suspension of deformable particles flowing in a quasi-two-dimensional Poiseuille flow. Thanks to a prec…
Delayed buckling of spherical shells due to viscoelastic knockdown of the critical load
Lucia Stein-Montalvo, Douglas P. Holmes, Gwennou Coupier
We performed dynamic pressure buckling experiments on defect-seeded spherical shells made of a common silicone elastomer. Unlike in quasi-static experiments, shells buckled at oste…
Post-buckling Dynamics of Spherical Shells
Marcel Mokbel, Adel Djellouli, Catherine Quilliet +2
We explore the intrinsic dynamics of spherical shells immersed in a fluid in the vicinity of their buckled state, through experiments and 3D axisymmetric simulations. The results a…
