Multiscale rheology of liquid foams
Aqueous foams are constituted of concentrated gas bubble dispersions in a surfactant solution. Like other complex fluids, such as emulsions or pastes, foam behaves as... -
Vibrating soap lm: origin of the dissipation
We investigate the complex dispersion relation of a transverse antisymmetric wave on a horizontal soap film. Experimentally, the complex wave number $k$ at a fixed...
