Presidential Young Investigator Award: Fundamental Studies of Droplet Evaporation

这项研究旨在研究与液滴蒸发有关的几个基本问题。所获得的信息有助于理解影响液滴蒸发速率的因素，并与与均匀成核、过热液体中的气泡生长和液滴的莱登弗罗斯特沸腾有关的更基本的问题有关。正在研究的具体问题包括：液滴内的均相成核和气泡增长；液滴是在高压下可混合的液体混合物；液滴在热/多孔陶瓷表面上的蒸发；以及液滴在接近零重力的情况下燃烧。虽然也进行了一些分析，但重点还是放在实验上。获取数据的主要手段是照相。

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.
