Collective hydrodynamic transport of magnetic microrollers
Gaspard Junot, Andrejs Cebers, Pietro Tierno
Abstract
for high particle spinning, the collective mean velocity linearly increases with the particle density. In this regime we analyse the clustering kinetics, and find that hydrodynamic interactions between the anisotropic, elongated particles, induce preferential cluster growth along a direction perpendicular to the driving one, leading to dynamic clusters that easily break and reform during propulsion.
