Collisions and rebounds of chemically active droplets
K. Lippera, M. Morozov, M. Benzaquen, S. Michelin
Abstract
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-uniform surface distribution. Most existing models focus on the self-propulsion of a single droplet in an unbounded fluid, which arises when diffusion is slow enough (i.e. beyond a critical Péclet number, .
