A regularised singularity approach to phoretic problems
Thomas D. Montenegro-Johnson, Sebastien Michelin, Eric Lauga
An efficient, accurate, and flexible numerical method is proposed for the solution of the swimming problem of one or more autophoretic particles in the purely-diffusive limit. The…
A reciprocal theorem for boundary-driven channel flows
Sebastien Michelin, Eric Lauga
In a variety of physical situations, a bulk viscous flow is induced by a distribution of surface velocities, for example in diffusiophoresis (as a result of chemical gradients) and…
Geometric pumping in autophoretic channels
Sebastien Michelin, Thomas D. Montenegro Johnson, Gabriele De Canio +2
Many microfluidic devices use macroscopic pressure differentials to overcome viscous friction and generate flows in microchannels. In this work, we investigate how the chemical and…
Phoretic self-propulsion at large Peclet numbers
Ehud Yariv, Sebastien Michelin
We analyse the self-diffusiophoresis of a spherical particle animated by a nonuniform chemical reaction at its boundary. We consider two models of solute absorption, one with a spe…
Autophoretic locomotion from geometric asymmetry
Sebastien Michelin, Eric Lauga
Among the few methods which have been proposed to create small-scale swimmers, those relying on self-phoretic mechanisms present an interesting design challenge in that chemical gr…
