| Research Abstract |
The concept of the effective turbulence intensity was introduced to the analysis of the turbulent flame propagation. In this concept, only smaller turbulent eddies among the wide scale range of eddies are considered to affect the propagating flame when the flame size is small. As the flame size increases, larger eddies may also contribute the flame propagation. The relationship between the turbulent burning velocity and the effective turbulence intensity during the flame propagation was established based on the flame properties such as flame front area, local curvature obtained in this study.
