Discrete rearranging disordered patterns, part I: Robust statistical tools in two or three dimensions
François Graner, B. Dollet, Christophe Raufaste +1
Discrete rearranging patterns include cellular patterns, for instance liquid foams, biological tissues, grains in polycrystals; assemblies of particles such as beads, granular mate…
An elastic, plastic, viscous model for slow shear of a liquid foam
Philippe Marmottant, François Graner
We suggest a scalar model for deformation and flow of an amorphous material such as a foam or an emulsion. To describe elastic, plastic and viscous behaviours, we use three scalar…
Discrete rearranging disordered patterns, part II: 2D plasticity, elasticity and flow of a foam
Philippe Marmottant, Christophe Raufaste, François Graner
The plastic flow of a foam results from bubble rearrangements. We study their occurrence in experiments where a foam is forced to flow in 2D: around an obstacle; through a narrow h…
A periodic microfluidic bubbling oscillator: insight into the stability of two-phase microflows
Jan-Paul Raven, Philippe Marmottant
This letter describes a periodically oscillating microfoam flow. For constant input parameters, both the produced bubble volume and the flow rate vary over a factor two. We explici…
Dry microfoams: Formation and flow in a confined channel
Jan-Paul Raven, Philippe Marmottant, François Graner
We present an experimental investigation of the agglomeration of microbubbles into a 2D microfoam and its flow in a rectangular microchannel. Using a flow-focusing method, we produ…
