Efforts to apply Large Eddy Simulation (LES), which is superior to the k-ε2 equation models to predicting turbulent flow in turbulent diffusion Flames have been made in recent years as the processing capacity of computer have been improved. Use of the dynamic SGS model to dynamically calculate the constant appearing in LES is expected to yield greater universality. In this study, we analtzed the methane-air turbulent diffusion flame in a combustor by LES with the Dynamic SGS model and examined the validity of this calculation method. The calculated temperature and CH4 mole fraction distribution were in fairly good agreement with the experimental results; the calculated CO mole fraction distribution did not agree well with the measured result, because a simple CO reaction mechanism. In future, to develop a combustion model suitable for LES including a combustion reaction scheme.
