Influence of physical mechanisms on soot formation and destruction in droplet burning

· Combust. Flame; (United States)
The dynamic parameters influencing soot formation and destruction in droplet burning are studied through time-resolved photography and sampling. Results show that, except for excessively sooty situations, the instantaneous amount of soot present follows the same trend as the instantaneous flame size, that near-complete oxidation of soot can be achieved by confining it within the regressing, closed flame, and that weak convection promotes soot oxidation while early extinction can lead to substantial soot emission. The effects of blending a sooty component with a nonsooty component of different relative volatility have also been investigated.
