摘要：
The characterization of the heat release rate is of great importance for studying the combustion process. In this work, the correlation between heat release rate and OH*, CH* chemiluminescence in methane inverse diffusion flame is explored with a numerical simulation over a wide range of oxygen/fuel equivalence ratios and methane flow rates. It is found that the flame heat release rate is mainly related to the formation and consumption of the species OH, C2H2, CH3, CH4, CO, CO2, H, H2O and O. The ground state OH concentration gradient is correlated with the heat release rate distribution, and the peak location of the gradient in the ground state OH concentration aligns with the peak location of the heat release rate. The outline of the OH* distribution is consistent with the profile of the maximum of the OH concentration gradient. CH* is used to indicate the main distribution of the heat release rate, and the outline of the OH* distribution coincides with the outline of the heat release rate.
