Presidential Young Investigation Award: Combustion and Laser Diagnostic Research

PI将利用他广泛的实验室经验来测量燃烧过程中化学物质的时间历史。先进的诊断（紫外拉曼，激光诱导荧光）将获得诸如H2，N2，O2和H2O等主要物质的各种稳定火焰的信息。关于一氧化氮（NO, NO2）的类似信息将有助于阐明湍流中一氧化氮的形成。最后将利用一种独特的高能量（每脉冲100 mJ）和重复频率（1MHz）的自由电子激光器研究非定常现象。目前有很多人对解决非常高速或非常不稳定条件下火焰的化学动力学（高超音速推进，脉冲燃烧器，湍流结构器）感兴趣。人们感兴趣的燃料的数量也在增加，因为经济效益使一些新化合物更具竞争力（或一些传统化合物竞争力下降）。PI的经验将很好地满足所有这些需求。他将对数据库作出有价值和准确的贡献。

The PI will use his broad laboratory experience to measure the time history of chemical species during a combustion event. Advanced diagnostics (UV Raman, laser induced fluorescence) will yield such information on such major species as H2,N2,O2, and H2O for a variety of steady flames. Similar information on nitric oxides (NO, NO2) will help elucidate nitric oxide formation in turbulent flows. Finally unsteady phenomena will be studied with the help of a unique free electron laser, which possesses high energy (100 mJ per pulse) and repetition rate (1MHz). There is a lot of current interest in resolving the chemical kinetics of flames for very high speed or very unsteady conditions (hypersonic propulsion, pulse combustors, turbulent structors). The number of fuels of interest is also increasing, as economics makes some new compounds more competitive (or some traditional ones less so). All these needs will be well served by the PI's experience. He will make valuable and accurate contributions to the data base.
