蒸发液滴中的流动与传质行为:理论与应用

摘要

The drying of droplet is a process with heat and matter transfer.It is a process that permeates most disciplines in modern technologies and has not been fully understood.The flow and mass transfer laws in the drying droplets and their application are reviewed in this paper.It mainly includes experiments aimed at principles for typical process of droplet drying and the correspon-ding matter flow modes, film patterns from drying polymer solution droplet, composite solution droplet, and complex droplets.Meanwhile, the applications of drying droplet theory in ink-jet printing, disease diagnosis and nanomaterial preparation are briefly analyzed.Finally, present situation and future application requirements for drying droplet theory are summarized and prospected.%液滴蒸发过程伴随着热量和物质的传输,是现代技术领域普遍存在而又未充分认识的一个复杂过程.综述了蒸发液滴中的流动与传质规律及其应用研究进展,主要包括典型的蒸发液滴过程及其中流动方式、聚合物溶液液滴蒸发成膜花样、复合材料溶液液滴蒸发成膜花样等液滴蒸发理论的实验研究.同时简要分析了蒸发液滴理论在喷墨打印、纳米材料制备等领域的应用研究.最后对聚合物溶液液滴蒸发理论的现状及未来应用需求进行了总结与展望.
