Quenching mechanism study of oscillating flame in micro channels using phase-locked OH-PLIF

This paper presents the development of phase-locked OH-PLIF imaging system and OH 2-line flame temperature measurement for the investigation of quenching mechanism of oscillating flame in external heated micro quartz channels. The oscillating flame is a periodic process of flame auto-ignition at the channel exit, propagation and quenching upstream. The periodic change of CH∗ chemiluminescence intensity of the oscillating flame is captured by a...
