STUDY OF THE EFFECT OF ELEVATED PRESSURES ON THE LAMINAR BURNING VELOCITY OF PROPANE-AIR MIXTURES

Abstract

Laminar burning velocities were obtained for three specific equivalence ratios of propane –air mixtures (Ø= 0.8, 1.0 & 1.3). The effect of elevated pressures at variable initial temperatures was also analyzed. It was found that the laminar burning velocity is reduced with the increase of pressure at constant temperature. At mixture high initial temperatures (350 K) the effect of pressure on laminar burning velocity was limited. The laminar flame speed results were compared with other researches and it was found a good agreement.
