Ternary Dewetting: The Flow Physics of Cleaning using Limited Resources

从粗糙、异质和结构化固体表面去除液体或去湿是许多工程和工业过程的核心，从溢油清理到家中织物和表面的清洁。迄今为止，大多数关于去湿的研究仅限于二元流体系统：在周围存在气体或液体浴的情况下的液滴去除。相比之下，该项目关注的是在三元流体系统中实现去湿，其中液滴同时与几个流体相相互作用。该项目的首要动机是调查这样一个过程是否可以导致润湿性改变，这是更本地化，可用于资源有限的环境（有限的水，聚合物和表面活性剂）。

The removal of liquids, or dewetting, from rough, heterogeneous and structured solid surfaces is central to many engineering and industrial processes, from oil spill cleanup to the cleaning of fabrics and surfaces at home. To date, the majority of studies on dewetting have been limited to binary fluid systems: a droplet removal in the presence of a surrounding bath of gas or liquid. In contrast, this project is concerned with achieving dewetting in ternary-fluid systems, where the droplet is simultaneously interacting with several fluid phases. The project's overarching motivation is to investigate whether such a process can lead to wettability alteration that is more local and can be employed in resource-constrained environments (limited water, polymers and surfactants).
