- 摘要：
- Using a shock tube facility, ignition delay times of methyl acetate (MA) were measured cover the temperature range of 1120-1760 K, equivalence ratio range of 0.5-2.0, pressure range of 1.2-10 atm and fuel mole fraction range of 0.5%-2.0%. An Arrhenius correlation for all the measured data was obtained through multiple linear regression. The correlation was further compared to the literature correlation [Akih-Kumgeh, B.; Bergthorson, J. M. Combust. Flame 2011, 158 (6), 1037-1048.], and discrepancy was found between the two studies. Four existing chemical kinetic models were used to simulate the measurements, and results suggested that the Princeton model and the Yang model gave better predictions on current ignition data compared to the Westbrook model and the Akih-Kumgeh model. By updating the base model of the Princeton model, a combined model was obtained and it gave the best prediction on current experimental data among all available models. Sensitivity analysis and reaction pathway analysis were conducted on the basis of the models who give reasonable predictions, i.e. the Princeton model, the combined model and the Yang model to gain a further insight in the ignition process of MA and make a comprehensive comparison on different kinetic models
