Concentration and Mass Distribution of Charged Species in Sooting Flames.
Abstract
Total concentration and mass distribution of charged species larger than about 300 amu were measured along the centerline of a premixed sooting acetylene/oxygen flat flame at 20 mmHg. The observed species, which include heavy hydrocarbon ions and charged soot particles, are of positive polarity. Heavy hydrocarbons appear to include both soot nuclei and surface growth intermediates. The concentrations of heavy hydrocarbon ions are much larger than the peak concentration of soot particles. Therefore ionic nucleation of soot particles is feasible for these conditions, and a tentative mechanism is described. (Modified author abstract)
