ABSTRACT 9526410 Williams UC-San Diego This accomplishments based continuation proposal focuses on the modeling of the detailed chemistry in various diffusion flames through the application of asymptotic-based techniques developed by the PI and is a logical extension of the work presently being carried out by the PI. New flame systems to be investigated will include (1) higher hydrocarbon flames, (2) higher alcohol flames, (3) hydrogen flames containing halogens, and (4) nitrogen containing flames. The production of the oxides of nitrogen in flames and the intrinsic stability and influences of strain will also be investigated. Special attention will be paid to the derivation of useful reduced kinetic schemes. The results will contribute to our knowledge of mechanisms of flame propagation, flame structure, flame instabilities and flame ignition and extinction.

摘要 9526410 Williams 加州大学圣地亚哥分校 这项基于成果的延续提案侧重于通过应用 PI 开发的基于渐近的技术对各种扩散火焰中的详细化学进行建模，并且是 PI 目前正在进行的工作的逻辑延伸。 待研究的新火焰系统将包括(1)高级烃火焰、(2)高级醇火焰、(3)含卤素的氢火焰和(4)含氮火焰。 还将研究火焰中氮氧化物的产生以及内在稳定性和应变的影响。 将特别关注有用的简化动力学方案的推导。 研究结果将有助于我们了解火焰传播、火焰结构、火焰不稳定性以及火焰点火和熄灭的机制。
