Transport, aggregation and wetting of assemblies of soft fibres - Camille Duprat (ECOLE POLYTECHNIQUE)

Abstract:

Fibrous media are present in a variety of systems, many involving an interaction with a liquid, in particular with liquid-air interfaces (e.g. liquid absorption in paper, impact of a drop on a cotton fabric, filtration of droplets from an aerosol with a fibrous filter, extrusion of fibrous gels, papermaking). I will illustrate some of the mechanisms at play in such fiber-liquid interactions with several model experiments, from the flow of fiber suspensions to the imbibition of model fibrous media.
