Application of rate-ratio asymptotics to the prediction of extinction for methanol droplet combustion

Asymptotic methods are employed to describe the flame structure and extinction of quasisteady, spherically symmetrical diffusion flames around methanol droplets. Starting with a short mechanism involving 14 steps, five of which are reversible, sequentially reduced overall descriptions of four, three, and two steps are obtained by investigating the character of the departure of the H atom and its associated radicals from steady states and by...
