Experimental study of micro-scale premixed flame in quartz channels

This paper presents (1) the development of observation and optical measurement system for the investigation of flame in ultra-thin quartz channels; and (2) the observation and analysis of premixed CH4/air flame propagation and quenching in three quartz combustors with chamber depth of 0.7 mm, 1.0 mm and 1.5 mm, respectively. Flame oscillation is interpreted and discussed according to well-resolved chemiluminescence images of the flame taken by...
