"Tuning Fluid Behavior Using Micro-Structures"


Multiscale couplings contribute to the rich behavior of complex fluids. In this talk, I will focus on systems in which the presence of micrometer-scale structures has critical macroscopic effects. We will first describe the wetting of fibers to demonstrate the influence of mechanical parameters on the morphology of capillary bridges and the drying of fibrous media. We will then discuss the sloshing dynamics of a liquid bath covered with foam. The addition of bubbles leads to a damping of the waves, through viscous dissipation in the micrometer-scale Plateau borders. Finally, we will consider particle-laden flows in microchannels that constitute a model porous media allowing the fluid to pass through but trapping contaminants. Once a clog is formed in a pore, incoming particles aggregate upstream, which leads to a dramatic reduction of the flow rate. We use this microfluidic approach to study the clog formation and the growth of the aggregate.
