Cecilia Richards Abstract The objective of this research is to investigate the effect of vortex dynamics on droplets dispersion, vaporization, and burning in round jets. The research will focus on the dispersion of drop and their vapor by large-scale vortical structures in nonreacting jet, and in reacting jets, and on the impact of droplet/eddy interaction on the reacting flow structure. An experimental study of a turbulent jet with point source droplet stream injection using planar imaging techniques, image analysis, and point measurements of droplet and gas phase statistics, will be performed. This research will yield insight on the effect of vortex dynamics on the structure and behavior of reacting two-phase flows, data from this study will be directly applicable to improved design of two-phase reacting devices, such as industrial furnaces, gas turbine combustors, and hazardous waste incinerators.

摘要本研究的目的是研究涡旋动力学对圆形射流中液滴分散、汽化和燃烧的影响。重点研究液滴及其蒸汽在非反应射流和反应射流中的大尺度涡旋结构弥散，以及液滴/涡旋相互作用对反应流动结构的影响。本文将使用平面成像技术、图像分析、液滴和气相统计的点测量，对具有点源液滴流注入的湍流射流进行实验研究。本研究将深入了解涡流动力学对反应两相流的结构和行为的影响，本研究的数据将直接应用于工业炉、燃气轮机燃烧器和危险废物焚烧炉等两相反应装置的改进设计。
