Abstract

The local values of turbulent burning velocity of propane-air homogeneous mixture in closed combustion chambers were measured from the difference between the flame propagation speed and the unburned gas velocity ahead of the average surface of the turbulent flame front. In turbulent flames produced by the flame passing through a grid and those propagating in turbulent swirl flow, the effects of turbulence characteristics on the burning velocity were investigated. The unburned gas velocity during flame propagation was measured with a laser Doppler velocimeter (LDV). The mean velocity and the turbulence intensity of flow during the short time interval immediately before flame arrival were determined by means of the digital filter of Butterworth type.
