Comparison of spectroscopic flame temperature measurements: Na-D line reversal, rotational and vibrational Raman, and OH absorption
Different spectroscopic methods are used for the measurement of flame temperature. This report compares measurement of temperature profiles for atmospheric premixed H/sub 2//O/sub 2//N/sub 2/ laminar flames using the methods of: (1) Raman scattering (N/sub 2/, vibrational and rotational temperatures); (2) line reversal (D-line of Na, electronic temperature); and (3) line ratio (OH, rotational temperature). Two separate burner designs are considered. To obtain the most accurate comparison possible, all measurements were made with the same burners and auxiliary gas-feed system. The theory for each technique is summarized and the sensitivity, accuracy, and convenience are compared. Necessary corrections are discussed. In general, the results indicate very good agreement (better than 98%) between the various methods for certain combinations of flame composition and burner type.
