Abstract

Laser induced fluorescence of the OH radical has been used for planar temperature measurement by means of a two-level vibrational model to describe the relationship between the population ratio of excited states and temperature. The quenching to vibrational transfer ratio between the excited states was used as a calibration parameter to fit the thermally assisted fluorescence (THAF) measurements to known temperature data. A rectangular shaped burner allowed for calibration and comparison of the thermally assisted temperature results with sodium line reversal data available in the literature for premixed methane-air flames. Excellent agreement between the two techniques was achieved for three different equivalence ratios. Overall, the applicability of THAF to planar temperature measurement was positively demonstrated in the present work.
