Probing the Dynamics of Self-Electrophoretic Swimmers using Lattice Boltzmann — •Michael Kuron1, Georg Rempfer1, Joost de Graaf2, and Christian Holm1 — 1Institut für Computerphysik, Universität Stuttgart, Deutschland — 2Institute for Theoretical Physics, Universiteit Utrecht, Nederland
Many simulational studies are available of the rich transient and collective behavior in catalytically-propelled colloids or microswimmers. However, virtually none consider both the hydrodynamic and phoretic fields and most do not take into account even one of them. We introduce a continuum model based on the lattice Boltzmann method that incorporates both effects and is capable of simulating the dynamic behavior of many swimmers. Our swimmers propel via experimentally relevant self-electrophoretic mechanisms with bulk reactions.
