Abstract

Line of sight Fourier transform infrared absorption spectra through low pressure premixed methane/nitrous oxide and methane/oxygen flames have been analyzed using computed tomography. The reconstruction method used is Abel inversion, which takes advantage of the fact that when the object of interest is axisymmetric, only one set of parallel projection data is necessary. Relative absorbances for several species in these flames have been mapped for various `slices' of the flame at different heights in the flame.
