A numerical simulation of a premixed flame stabilized by a bluff body was performed using LES turbulent model and a new turbulent combustion model. In the previous work, the authors evaluated a local quenching effect due to a flame stretch and proposed a new combustion model including turbulent effects. The model also includes temperature effect of unburned gas and the pressure effect in a combustor. Due to the strong organized motion created by the bluff body, we could see fluctuations of the premixed flame. Further more, the distributions of the time-averaged velocity, temperature and intensity of the velocity fluctuation were compared with experimental data. The calculated results were in good agreement with the experimental ones.
