Abstract
Effects of radiative heat transfer on the structure of premixed CH4-Ak flames were investigated by solving the species and overall energy conservation equations simultaneously with the nongray radiative transfer equation. Nongray effects from CO2, CO, H20 and CH, were treated through the use of a narrow-band model. Results were obtained for a wide range of pressures, equivalence ratios and mass-flow rates. For regions where most of the experimental data are taken, up to 0.5 cm above the burner, radiative losses are negligible. However, it was shown that the maximum flame temperature occurs beyond the location where experimental measurements are taken. Hence, some of the discrepancies between experimental and theoretical calculations reside on the lack of chemical equilibrium among the combustion products. In addition, radiative heat feedback to the burner surface represents an important component of the total energy transferred to the burner.
