Theory of Flames with Real Chemistry

这一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。要研究的新火焰系统将包括(1)高碳氢化合物火焰，(2)高酒精火焰，(3)含卤素的氢火焰，(4)含氮火焰。研究了火焰中氮氧化物的生成、内在稳定性和应变的影响。将特别注意有用的简化动力学格式的推导。这些结果将有助于我们了解火焰的传播机制、火焰结构、火焰不稳定性以及火焰的点燃和熄灭。

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.
