Droplet coalescence is the key to breaking emulsions, that is, separating oil from water. This process underpins the recovery of crude oil and the remediation of industrial and environmental waste-waters. Through a unique and novel experimental program that simultaneously tracks drop trajectories up to the millimetre scale and drop deformations in the nanometre scale, this project aims to fill a fundamental gap in our understanding of such coalescence events. A complete theoretical model of coalescence will result, forming a predictive framework for separating emulsions to recover pure oil and water, and laying the foundation for using compound drops to tune the optical properties of surface for speciality applications.

液滴聚结是破乳即油水分离的关键。这一过程是原油回收以及工业和环境废水治理的基础。通过一个独特的和新颖的实验计划，同时跟踪下降轨迹到毫米级和下降变形在纳米级，该项目旨在填补我们的理解这样的聚结事件的根本差距。一个完整的聚结理论模型将导致，形成一个预测框架，分离乳液回收纯油和水，并奠定了基础，使用复合液滴调整表面的光学性能的特殊应用。
