氢在高速吸气燃烧中是一种有实用价值的燃料，由于特征流动时间较短，有限速率化学动力学的影响有望发挥重要作用。相关的燃烧问题可以通过考虑层流、逆流结构来研究，其中高速燃烧中遇到的高应变率会导致化学不平衡的影响变得重要。本章介绍了这些火焰的结构和熄灭特性。它对上一章的材料进行了扩展，其中回顾了背景参考文献。
Hydrogen is a fuel of practical interest in high-speed air-breathing combustion, where effects of finite-rate chemical kinetics are expected to play a significant role as a consequence of the short characteristic flow times. Associated combustion problems may be investigated by considering laminar, counterflow configurations, where high strain rates encountered in high-speed combustion cause effects of chemical nonequilibrium to become important. The present chapter concerns the structures and extinction characteristics of these flames. It expands on material of the preceding chapter, in which background references are reviewed.
