    This study focused on calculating the turbulent flame speed in a V-shape turbulent premixed flame using a circular fractal turbulence generator. In previous studies [Part. I turbulent flow characteristics in a Non-Reacting Field], [Part. II characteristics of turbulent flame structures], the non-reactive turbulent flow and turbulent flame structure for the V-shape flame of a fractal turbulence generator were investigated in detail. Two types of turbulent burning velocities are evaluated : local displacement and consumption speeds. The local consumption speed is calculated via the image processing of flame surface density. The results show that turbulent burning velocity increases much with fractal grids as compared with the conventional grids perforated plate and mesh. Finally, it was confirmed that the correlation between the turbulent flow factor and the two turbulent burning velocities of each turbulence generator was collapsed well with a specific correlation equation.
