A comprehensive experimental and improved kinetic modeling study on the pyrolysis and oxidation of propyne

To improve our understanding of the combustion characteristics propyne, new experimental data for ignition delay times (IDTs), pyrolysis speciation profiles and flame speed measurements are presented in this study. IDTs propyne were obtained at equivalence ratios 0.5, 1.0, 2.0 ‘air’ pressures 10 30 bar, over a wide range temperatures (690–1460 K) using rapid compression machine high-pressure shock tube. Moreover, experiments performed single-pulse tube to study 2 bar pressure temperature 1000–1600 K. In addition, laminar speeds studied an unburned gas 373 K 1 ratios. A detailed chemical kinetic model is provided describe pyrolytic across wide-ranging set data. This mechanism shows significant improvements predictions IDTs, fuel compared AramcoMech3.0.
