• Turbulent premixed flames of gas turbine combustors are mainly classified into the Thin Reaction Zone (TRZ) regime and they are sometimes classified into the Corrugated Flamelets (CF) regime or the Wrinkled Flamelets (WF) regime when turbulence is weak. Then the turbulent premixed combustion model which can treat both TRZ, CF and WF flames was developed in this study. The diffusion enhancement effect by turbulent eddies within the preheat zone, the flame stretch effect and the increasing rate of flame surface area were modeled here. The verification analysis was done for the TRZ flame stabilized by a bluff body and it was confirmed that the numerical result calculated using the developed model was excellently corresponding to the experimental data.
