Ignition and Unsteady Flame Propagation in Turbulent Reactive Flows.

Abstract

A conceptual model was developed for the study of turbulent flame propagation comparison of measured apparent turbulent-flame-propagation speeds with limit curves derived on the basis of this model indicated the importance of rate augmentation within the turbulent flame structure. Spectral changes observed in the thermal structure of premixed methane-air V-flames stabilized behind a cylindrical flameholder indeed showed the existance of reaction-augmented turbulence in the smaller eddies, which would account for the increase in the propagation speeds.
