Spontaneous onset of convection in a uniform phoretic channel
Sébastien Michelin, Simon Game, Eric Lauga +2
Phoretic mechanisms, whereby gradients of chemical solutes induce surface-driven flows, have recently been used to generate directed propulsion of patterned colloidal particles. Wh…
Modeling chemo-hydrodynamic interactions of phoretic particles: a unified framework
Akhil Varma, Sebastien Michelin
Phoretic particles exploit local self-generated physico-chemical gradients to achieve self-propulsion at the micron scale. The collective dynamics of a large number of such particl…
Universal optimal geometry of minimal phoretic pumps
Sebastien Michelin, Eric Lauga
Unlike pressure-driven flows, surface-mediated phoretic flows provide efficient means to drive fluid motion on very small scales. Colloidal particles covered with chemically-active…
Nonlinear dynamics of a chemically-active drop: from steady to chaotic self-propulsion
Matvey Morozov, Sebastien Michelin
Individual chemically active drops suspended in a surfactant solution were observed to self-propel spontaneously with straight, helical, or chaotic trajectories. To elucidate how t…
Phoretic and hydrodynamic interactions of weakly-confined autophoretic particles
Eva Kanso, Sebastien Michelin
Phoretic particles self-propel using self-generated physico-chemical gradients at their surface. Within a suspension, they interact hydrodynamically by setting the fluid around the…
