Measurement of the Line Reversal Temperature of OH in CH4/N2O Flames
Abstract
The reversal technique is universally accepted by the combustion community as an accurate method for flame-temperature measurements. This technique has generally involved the use of Na seeded in flames. However, for many burner types seeding is difficult. This work describes band-reversal measurements using OH, which occurs naturally in all flames containing oxygen and hydrogen. The theory is discussed as well as use of the technique in the burnt gas region of CH4/N2O flames. The experimental results are compared with laser-excited fluorescence temperature measurements also performed in this laboratory. Excellent agreement was achieved.
