Numerical Investigation of CH₄/CO₂/Air and CH₄/CO₂/O₂Counterflow Premixed Flames with Radiation Reabsorption

Effects of radiative heat loss on temperatures and extinction characteristics of CH4/CO2air and CH4/CO2/O2 counterflow premixed flames were numerically investigated by using the detailed chemistry and transport properties with emphasis on assessing the importance of radiation reabsorption. Radiative transfer was calculated using the discrete ordinate method along with the grey gas assumption. Results show that radiation reabsorption has little...
