โœฆ Synopsis


An attempt is made to examine the con"guration and propagation characteristics of premixed turbulent #ame in a weak turbulence region. A laser tomography technique is used to obtain the #ame shape, and quantitative analysis is performed. It is found that the turbulent #ame front can be classi"ed into the active and the inactive part for the #ame propagation, where the former is the convex part of #ame toward the unburned mixture and the latter is toward the burned gas. In this paper, the local burning velocity and the local #ame front curvature are determined directly by sequential #ame tomograms.

The paper describes experiments in which high frequency electric fields were applied across flames generated by the action of laser-induced sparks. The objective of the study was to establish whether such fields affect the rates of flame propagation in mixtures at one atmosphere pressure of methane/
