Dissipation in a sheared foam: from bubble adhesion to foam rheology

Résumé

The link between the rheology of 3D aqueous foam and the adhesion of neighbouring bubbles is tested by confronting experiments at two different length scales. On the one hand, the dynamics of adhesion are probed by measuring how the shape of two bubbles in contact changes as their center-to-center distance is modulated. On the other hand, the linear viscoelastic behavior of 3D foam prepared with the same soapy solution is characterized by its complex shear modulus. To connect the two sets of data we present a model of foam viscoelasticity taking into account bubble adhesion.
