| description | The effects (chemical, thermal, transport, and radiative) of CO<sub>2</sub> added to the fuel side and oxidizer side on the flame temperature and the position of the flame front in a one-dimensional laminar counterflow diffusion flame of methane/N<sub>2</sub>/O<sub>2</sub> were studied. Overall CO<sub>2</sub> resulted in a decrease in flame temperature whether on the fuel side or on the oxidizer side, with the negative effect being more obvious on the latter side. The prominent effects of CO<sub>2</sub> on the flame temperature were derived from its thermal properties on the fuel side and its radiative properties on the oxidizer side. The results also highlighted the differences in the four effects of CO<sub>2</sub> on the position of the flame front on different sides. In addition, an analysis of OH and H radicals and the heat release rate of the main reactions illustrated how CO<sub>2</sub> affects the flame temperature. |
