OH/アセトン同時PLIF計測による予混合火炎の火炎帯の可視化(オーガナイズドセッション6 乱流燃焼研究の最前線)
詳細
This paper explores that simultaneous OH/acetone PLIF can be applied to visualize "flame zone" of premixed flame. OH and acetone can be excited by a Nd:YAG pumped dye laser with a frequency doubled 283.222nm tuned to the Q_1 (7) OH line fluorescence signal, and appropriate band pass filter mounted to ICCD system is selected to collect these fluorescences. OH and acetone act as tracers of burned region and unburned region, respectively. The results indicate that only OH and acetone are excited with the laser, and the flame zone could be seen as dark separated zone between the distribution of OH and acetone in PLIF images.
