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.
