Abstract: A20.00003 : Collective Dynamics of Quincke Rollers with Fully Resolved Hydrodynamics
8:48 AM–9:00 AM
John J Molina
We report our successful simulations on the collective motions of Quincke rollers, which depends on the strength of dipole moment induced on a particle, the area fraction of particles, and the strength of interparticle attraction, with fully resolving the hydrodynamics of the system. In particular, we want to emphasize that the polar liquid is unstabilized by the lubrication effect acting between rotating particles at high densities.
