Student Support in Connection with Fluorescent Diagnostics and Fundamental Droplet Processes

摘要

The project funded under U.S. ARO grant DAAG055-97-1-0265 was directed toward the development and use of fluorescent diagnostics in the understanding of the heating and evaporation of droplets and sprays, the role of shear in atomization processes, and the application of fluorescent diagnostics to various aerodynamic problems. At the University of Texas at Dallas (UTD), the following fluorescent diagnostic projects were undertaken: (1) real time measurements of shear possibly in fuel spray ligaments, (2) simultaneous determination of temperature and oxygen, (3) liquid film thickness (particularly on cylinder walls), and (4) mixing of liquids. The first three projects involved students supported under this AASERT grant. A new method for real-time 2-D imaging of fuel film thickness has been published, and a new concept for imaging of shear (strain rate) in fluids has been tested.
