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…
Collisions and rebounds of chemically-active droplets
Kevin Lippera, Matvey Morozov, Michael Benzaquen +1
Active droplets swim as a result of the nonlinear advective coupling of the distribution of chemical species they consume or release with the Marangoni flows created by their non-u…
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…
Stochastic modelling of a freely rotating disk facing a uniform flow
E. Boujo, O. Cadot
The fluid-structure interaction between a thin circular disk and its turbulent wake is investigated experimentally and described with a low-order stochastic model. The disk faces a…
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…
