Abstract

Droplet multiphase flow is a part of many technologies and processes, but the hydrodynamics of drop-drop interactions and the potential of multidrop ordering dynamics is poorly studied. In contrast, solid particles have been extensively investigated in inertial microfluidics, establishing the rule that higher inertia leads to better ordering. We instead find that for drops, ordering is not achieved and worsens with higher inertia in the conventional straight channel geometry, while Dean flow is required to order drop trains. These results present unexpected inertial ordering dynamics in drops, and offer potential new utility to applications in droplet microfluidics.
