Abstract: M19.00006 : Self-propulsion of chemically-active droplets in a cylindrical capillary*
2:15 PM–2:28 PM
Here, we present a novel numerical framework based on moving embedded boundaries to analyse the nonlinear self-propulsion dynamics of chemically-active droplets in complex spatial configuration. We further use that framework to study the self-propulsion of an active droplet along a capillary tube, focusing specifically on the impact of the confinement intensity (i.e. the particle-to-tube radius ratio) on the dynamics and propulsion characteristics.
