Abstract
A time-resolved two-dimensional Rayleigh seatiering technique for mapping the temperature Held or a nonpremixed methane-hydrogen flame is presented. The laser Rayteigh scattered tight from an illuminated plane intersecting the flow field was digitized in an 8,000 data point array. The two-dimensional jnd quantitative character or the data makes it possible to apply calculations to the data, e.g., ensemble averaging and pattern recognition, to obtain more information on the flame structure. The results of these calculations are presented along with instantaneous measurements of the temperature field of the flame.
