Presidential Young Investigation Award: Combustion and Laser Diagnostic Research

PI将利用其广泛的实验室经验来测量 燃烧事件期间化学物质的时间历程。 先进的诊断（紫外拉曼，激光诱导荧光）将 产生关于H2、N2、O2和H2O等主要物质的信息 各种稳定的火焰。 关于硝酸的类似信息 氧化物（NO，NO2）将有助于阐明一氧化氮形成， 湍流 最后，将研究非定常现象， 一个独特的自由电子激光器的帮助下，具有高 能量（每个脉冲100 mJ）和重复率（1 MHz）。 目前人们对解决这种化学物质很感兴趣， 极高速或极不稳定火焰动力学 条件（高超音速推进，脉冲燃烧室，湍流 structors）。 感兴趣的燃料的数量也在增加， 由于经济因素使一些新化合物更具竞争力（或 传统的少）。 所有这些需求都将得到很好的满足 PI的经验。 他将使宝贵的和准确的 对数据库的贡献。

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.
