Burning velocity is one of the important properties of premixed turbulent flames. Premixed turbulent flames are. in general, subjected to the thermo-diffusive effects in addition to the increase in the flame front area due to the influence of turbulence, hi order to independently evaluate these two effects on turbulent flames and then burning velocity, ethane flames, which have a Lewis number around unity and can therefore be considered insensitive to the thermo-diffusive effects, were examined. Flame front morphologic properties such as a Fractal dimension were obtained by Fractal analysis of flame front tomography, and burning velocity was obtained by Schlieren technique. A novel correlation of turbulent burning velocity with Fractal properties of flame front was proposed.
