Abstract

Outwardly propagating spherical flames were used to measure laminar flame speeds of acetylene/oxygen mixtures over broad ranges of equivalence ratio (θ=0.6-2) and pressure (P=1-20 atm). For the flame speed in air at atmospheric pressure, the present data agree with the previous work in the literature. However, for both lean and rich acetylene mixtures at elevated pressures, the measured flame speeds are considerably lower than model predictions. Path flux and sensitivity analysis on the oxidation chemistry of acetylene are conducted and the important reactions that contribute to the deviation of flame speeds are identified.
