Laminar Flame Speed Measurements of Methyl Octanoate, n-Nonane, and Methylcyclohexane Conference Paper uri icon

abstract

  • Laminar flame speeds of methyl octanoate (C9H18O2), n-Nonane (n-C9H20), and methylcyclohexane (MCH) were measured using schlieren imaging of flame propagation in a heated, constant-volume cylindrical vessel at 1 atm. Two initial experimental temperatures were utilized: 130 C and 170 C. Differences in laminar flame speed were more pronounced under fuel-lean conditions, with methyl octanoate and MCH lower relative to n-nonane by 8.2 cm/s and 3.0 cm/s, respectively. The methyl ester species displayed a slight shift in peaklaminar- flame-speed equivalence ratio (1.15) relative to the hydrocarbons (1.07) which led to higher flame speeds at fuel-rich equivalence ratios. Constant-volume measurements of MCH flame speeds were compared to diffusion flame measurements from the literature and were observed to be consistently lower (~ 2 - 5 cm/s at peak flame speed). 2013 by The Authors.
