    초록 Detailed flame structures of the counterflow flames formed for different inlet temperature and CO2, addition are studied numerically. The detailed chemical reactions are modeled by using the CHEMKIN-Ⅱ code. Only the CO2 and H2O are assumed to participate by absorbing the radiative energy while all other gases are assumed to be transparent. The discrete ordinates method and the narrow band based WSGGM with a gray gas regrouping technique(WSGGM-RG) are applied for modeling the radiative transfer through non-homogeneous and non-isothermal combustion gas mixtures generated by the opposed flow flames. The results compared with SNB model show that the WSGGM-RG is successful in modeling the counterflow flames with non-gray gas mixture. The numerical results show that the addition of CO2 to the oxidant lowers the peak temperature and NO concentration in flame. But preheating of fuel and oxidant comes to increase the peak temperature and NO concentration.
