Abstract

The KrF laser was employed to study NO fluorescence in lean-bum as well as in soot-bum flames. Blue-shifted NO fluorescence was observed in both of the flames. For both of the flames, the fluorescence intensity of NO and its relative background noise signal were measured with respect to the concentration of seeded NO molecule in the flame and the laser intensity. The results were analyzed qualitatively. Also, NO concentration distribution in the lean-bum flame was qualitatively determined from the intensity of the NO fluorescence. cence.

KrF 레이저를 여기광원으로 사용하여 희박연소화염과 매연화염에서 각각 청색편이된 NO형광 신호를 측정하였다. 두 화염에 대해서 여기광의 세기와 NO 첨가량에 따른 NO 신호와 배경잡음의 세기를 계측하고 그 결과를 정성적으로 분석하였다. 또한 희박연소화염에서 위치에 따른 NO 신호의 세기도 관측하였다.
