Flame Phenomenology for Premixed Methane and Propane/Air in Developed Meso-scale Channels at Ambient Conditions
Abstract: This paper reports the development of a meso-scale channel for propagation of methane and propane-air mixtures at low Reynolds number. An experiment was conducted in 3, 4 and 5 mm internal quartz tube diameters at premixed conditions of the fuel/air. The tubes were vertically mounted and sometimes preheated uniformly laterally. Uniformly laterally heating gives a zero temperature gradient. Flame phenomenology at different equivalence ratios (φ) of the mixture was discussed. …
