The sooting process during combustion is described by a theory based on cluster kinetics. The likelihood of soot formation via soot clusters at higher temperatures is suggested from the fully kinetic calculations in which carbon vapors (C_1-C_5) and polyacetylenes are assumed to be as the colliding partners for cluster reactions. The predicted results of the proposed theory well explain both the bell shaped temperature dependence of soot yields and the rapid soot formation as known from shock-tube experiments. It is shown that the small clusters are mainly generated via C_2H and they grow into large clusters on the reaction with carbon vapors at moderately high temperatures while they are decomposed into carbon vapors at extremely high temperatures. Furthermore, the effects of pressure and temperature history on soot formation are discussed.
