Abstract

The structure of methane and propane flames in a counterflow burner is studied. The method used for the concentration measurement of CO, which is a reaction intermediate and maintains a low concentration in the flames, is from the modulation dip in the spectrum of broadband coherent anti-Stokes Raman spectroscopy (CARS) arising from the cold-band Q-branch resonant signal of CO superimposed on the nonresonant background. The measured CO profiles together with the temperature and the velocity, using nitrogen CARS and laser Doppler velocimetry, are compared with the numerical results accounting for the detailed kinetics suggested by Peters [1993] with plug flow assumption.
