- Abstract
- Hydrogen atom abstraction by OH, H, and O: is the dominant mechanism in flames for the formation of hydrocarbon free radicals. For fuel-rich conditions, unsaturated radicals and acetylene react to produce polycyclic aromatic hydrocarbons, which are often invoked as soot precursors. Hydroxyl radicals have also been implicated as the dominant oxidizer of soot particles. Thus, OH, H, and O are important in both soot inception and oxidation. This paper examines whether or not it is possible to accurately estimate hydrogen and oxygen atom concentrations using either full equilibrium or partial equilibrium assumptions.
