Abstract
The oxidation of propyne was studied experimentally in an atmospheric-pressure flow reactor and in laminar premixed flames. Species profiles were obtained for propyne oxidation experiments conducted in the Princeton turbulent flow reactor (PTFR) in the intermediate- to high-temperature range (∼1170 K) for lean, stoichiometric, and rich conditions. Laminar flame speeds of propyne/(18% O2 in N2) mixtures were determined, over an extensive range of equivalence ratios, at room temperature and atmospheric pressure, using the counterflow twin flame configuration. A detailed chemical kinetic model of high-temperature propyne oxidation, consisting of 437 reactions and 69 species, was developed. It is shown that this kinetic model predicts reasonably well the flow-reactor and flame-speed data determined in this study and the shock tube ignition data available in the literature. The remaining uncertainties in the reaction kinetics of propyne oxidation are discussed.
