1507358 (Ju)This proposal brings an extensive suite of experimental tools to study the reaction phenomenon of basic fuels that exist in more complicated fuels. These new tools developed at Princeton University allow researchers to look at the phenomenon with sensitivity that has not previously existed, especially under high-pressure conditions common in engines. The principal investigators propose to involve graduate students in the research and outreach activities using the Princeton Energy for Community Certificate Program.A new, highly sensitive, quantitative mid-IR FRS (Faraday Rotation Spectroscopy) combustion diagnostic method for HO2 and OH will be developed. The proposed mid-IR FRS/IR-LAS integrated photolysis flow reactor will provide transformative capabilities and enable accurate quantification of key elementary reaction rates at low and intermediate temperatures. The measured HO2/OH, and other intermediate species, flame speeds, and elementary rate constants will fill the gap of knowledge of the current understanding of combustion kinetics at low temperature and high pressure, and will play a critical role in developing a validated, high pressure and low temperature kinetic mechanisms for the following common and important base fuels: methyl formate, methanol, and dimethyl ether (DME). The obtained high pressure methanol, methyl formate, and DME kinetic mechanisms will form the base mechanisms for other larger hydrocarbon fuels, alcohols, biodiesels, and esters.

1507358（Ju）该提议带来了一套广泛的实验工具来研究存在于更复杂燃料中的基本燃料的反应现象。普林斯顿大学开发的这些新工具使研究人员能够以前所未有的灵敏度观察这种现象，特别是在发动机常见的高压条件下。 主要研究人员建议利用普林斯顿能源社区证书项目的研究和推广活动，开发一种新的、高灵敏度的、定量的中红外FRS（法拉第旋转光谱）燃烧诊断方法。拟议的中红外FRS/IR-LAS集成光解流动反应器将提供变革能力，并能够在低温和中温下准确量化关键的基元反应速率。测量的HO 2/OH，和其他中间物种，火焰速度，和基本速率常数将填补差距的知识，目前的理解在低温和高压下的燃烧动力学，并将发挥关键作用，在开发一个有效的，高压和低温动力学机制，为以下常见的和重要的基础燃料：甲酸甲酯，甲醇，和二甲醚（DME）。所获得的高压甲醇、甲酸甲酯和DME动力学机理将形成其它较大烃燃料、醇、生物柴油和酯的基本机理。
