Abstract
Typical methods used to measure dynamic interfacial properties of multiphase liquid systems often employ drops that are much larger and flows that are much simpler than those encountered in typical processing applications. A microfluidic approach is used here to measure dynamic structure and kinetics in multiphase systems with drop sizes comparable to those encountered in applications and flow complexity that is easily adjustable. The internal circulation and deformation of an isolated aqueous droplet in oil (paraffin and canola) is measured using particle tracers and a detailed shape analysis, which is capable of measuring sub-micron deviations in drop shape. Deformation dynamics, detailed drop shape, interfacial tension, and internal circulation patterns and velocities are measured in Poiseuille and transient elongational flows. Mass transfer of surface active solutes has also been explored.Proceedings Title
