Premixed Turbulent Flame Propagation.

Abstract

A pulsed flame flow reactor has been developed for the study of one-dimensional, freely propagating, premixed turbulent flames over a broad range of turbulence Reynolds and Damkohler numbers. Laser Doppler velocimetry is used to characterize the turbulent flow field ahead of the flame in terms of its intensity, length scale and energy spectrum. Two-dimensional imaging is used to characterize the turbulent flame structure. Preliminary results indicate that the method of fractal analysis may be useful for quantifying turbulent flame structure in order to evaluate the effect of turbulence on flame propagation through changes in the flame structure. Keywords: Premixed turbulent combustion; Catalytic combustion; Catalytic ignition.
