- Abstract
- It has been shown that a criteria for flame extinction can be described by the Damkohler Number which is the ratio of a characteristic flow or diffusion time to a characteristic chemical reaction time. As the Damkohler Number is reduced the fuel burning rate gradually decreases until a critical value is attained when the flame will abruptly extinguish. The objective of this study is to investigate differences in the detailed chemical mechanisms which control the kinetics of non-premixed flames as they approach extinction by stretch, inhibition, and dilution.
