Collective Dynamics in a Binary Mixture of Hydrodynamically Coupled Microrotors
Collective Dynamics in a Binary Mixture of Hydrodynamically Coupled Microrotors
We study, numerically, the collective dynamics of self-rotating nonaligning particles by considering a monolayer of spheres driven by constant clockwise or counterclockwise torques. We show that hydrodynamic interactions alter the emergence of large-scale dynamical patterns compared to those observed in dry systems. In dilute suspensions, the flow stirred by the …
