U.S. Germany Cooperative Research: High-Pressure Laser-Induced Fluorescence Studies on Nitric Oxide and Molecular Fuel Tracers

0089149汉森该奖项支持罗纳德·汉森和斯坦福大学的学生与德国海德堡大学物理化学系的尤尔根·沃尔夫勒姆合作。由该奖项资助的研究将专注于开发高压燃烧过程中基于激光的诊断测量。需要解决的一个领域是，需要在高压下对一氧化氮进行激光诱导荧光定量测量，在这种情况下，谱线的压力展宽会产生来自存在的任何分子氧的干扰。这一问题将利用这家德国集团在高压燃烧器方面的专业知识和斯坦福大学的一个新实验设施。要研究的第二个问题是高压下燃料/空气混合系统的分子燃料示踪剂的特性。每个研究小组将使用具有不同化学结构的分子示踪剂，合作将允许直接比较或两种不同的方法。这种联合、合作的研究努力为初级研究人员带来了巨大的机会，就这一提议所做的工作将有助于使德国和美国研究小组之间的关系制度化。

0089149HansonThis award supports Ronald Hanson and students from Stanford University in a collaboration with Juergen Wolfrum of the Department Physical Chemistry at the University of Heidelberg, Germany. The research funded by this award will focus on developing laser-based diagnostic measurements during high-pressure combustion. One area to be addressed is the need for quantitative laser-induced fluorescence measurements of nitric oxide at high pressures where pressure broadening of the spectral lines produces interference from whatever molecular oxygen is present. This problem will make use of the German group's expertise in high-pressure burners and a new experimental facility at Stanford. A second problem to be worked on is the characterization of molecular fuel tracers for fuel/air mixing to systems under high pressure. Each research group will use molecular tracers with different chemical structures, and the collaboration will allow direct comparison or the two different approaches. The opportunity this joint, collaborative research effort presents junior researchers is substantial, and the work done on this proposal will help institutionalize the relationship between the German and U.S. research groups.
