Experimental and ocmputational study of CH,Ch,and OH in an axisymmetric laminar diffusion flame

摘要

In this study,we extend the results of previous combined numericla and experimental investigations of an axisymmetric laminar diffusion flame in which difference Raman spectroscopy,laser-induced fluorescence (LIF),and a multidimensional flame model were used to geenrate profiles of the temperature and major and minor species.A procedrue is outlined by which the number densities of ground-state CH (X~2II).excited-state CH (A~2#DELTA#,denoted CH),and excited-state OH are measured and modeled.
