Turbulent burning velocity of spherically propagating flame kept increasing with flame propagation. The turbulence which effectively wrinkles the flame front may be increasing with flame progress. Such turbulence intensity is called effective turbulence intensity and it is estimated from energy spectrum of turbulence. The relationship between burning velocity of spherically propagating turbulent flame and effective turbulence intensity was estimated. As a result, it is found that turbulent burning velocity is well correlated with turbulence Reynolds number based on Taylor micro scale and effective turbulence intensity regardless of turbulence intensity.
