The dilutive, chemical and radiative effects of CO2on the soot inception, condensation and HACA growth processes in laminar co-flow Jet-A1 kerosene diffusion flames were numerically investigated by employing detailed chemical mechanisms and soot sectional models. The results showed that the addition of CO2dramatically decreased the maximum temperature (by 92 K)and soot volume fraction (by 41.0%). The dilutive effect of CO2 contributed the most to the decrease of temperature and soot volume fraction. It also was the main factor in the decrease of soot inception, condensation and HACA growth processes. The chemical effect of CO2had little impact on the decomposition of fuels into light hydrocarbons, but obviously limited the growth of light hydrocarbons to A1. The radiative effect of CO2decreased the maximum temperature and soot volume fraction by 13 K and 5.2% (from 1.92 to 1.82 ppm). It had little impact on the soot inception, condensation and HACA growth rates.
