Soot prediction in a turbulent methane/air flame accounting for both gas and particulate radiation

Control of soot production and oxidation, and reduction of the ensuing emissions from combustion processes, are among the main problems that need to be solved to obtain an effective heat generation from hydrocarbon–fuelled flames, and to reduce the harmful impact of fossil fuels on the environment and human health. In the present work, numerical predictions of soot emissions in a methane-air flame at atmospheric pressure are presented, taking into account the interactions between turbulent combustion, soot formation and radiative heat transfer, from both gas and particulate
