Abstract:

Diffusion flames originating from gaseous jets, liquid pools, or even solid materials frequently exhibit a periodic flickering behavior, whose effect on the chemical fields within the flame is not understood. In particular, the slow rates of soot particle inception chemistry and of carbon monoxide oxidation might be expected to result in strong sensitivity of soot and CO production to the complex, time-varying flowfields present in flickering flames; this would have important consequences for flame radiation and the emission of smoke and CO.
