The research is directed toward studying several fundamental problems associated with evaporation of liquid droplets. The information obtained contributes to an understanding of factors affecting droplet evaporation rates, and is relevant to more fundamental problems associated with homogeneous nucleation, bubble growth within superheated liquids, and Leidenfrost boiling of droplets. Specific problems being studied are: homogeneous nucleation and bubble growth within droplets which are miscible mixtures of liquids at elevated pressures; evaporation of liquid droplets on hot/porous ceramic surfaces; and combustion of droplets in near-zero gravity. The emphasis is on experiment, though some analyses are also performed. The principal means of data acquisition is photographic.

本研究旨在研究几个基本问题 与液滴的蒸发有关。 的信息 获得有助于理解影响液滴的因素 蒸发率，并与更基本的问题有关 与均质成核有关， 过热液体和液滴的莱顿弗罗斯特沸腾。 具体 所研究的问题是：均匀形核和气泡生长 在作为液体的可混溶混合物的液滴内， 压力;热/多孔陶瓷上液滴的蒸发 表面;以及在近零重力下液滴的燃烧。 的 重点是实验，虽然也进行了一些分析。 获取数据的主要手段是照相。
