ABSTRACT:
A method for spatially resolving flame temperatures in which a temperature-dependent wavelength region of a molecule radical spectrum and a normalization wavelength region of the molecule radical spectrum suitable for normalizing spectral data are identified. An algorithm based upon a relationship between a temperature-dependent intensity range within the temperature-dependent wavelength region at a plurality of temperatures and a normalized intensity range within the normalization wavelength region is formulated. Flame spectral data from a flame is obtained and the algorithm is applied to the flame spectral data, resulting in generation of a flame temperature profile of the flame.
