Methane-air flame thermometry using planar lase-induced fluorescence (PLIF)

Abstract

Temperature measurements were performed in a central crosssection of a partially premixed atmospheric methane-air flame of a laboratory burner using two-line planar laser-induced fluorescence (PLIF) of OH radicals and coherent anti-Stokes Raman scattering (CARS) by H2 molecules. The results of a comparative analysis of 2D PLIF and singlepoint CARS thermometry of the flame are presented.
