The standard deviations of these measurements were estimated using both the published experimental uncertainty and the scatter error of the data series. 14 detailed reaction mechanisms were investigated using the collected experimental data. The results show significant differences between the performances of the various mechanisms. The four best-performing mechanisms are Aramco-2.0-2016, Aramco-3.0-2018, NUIGMech-1.1-2020, and Yang-2020 (in this decreasing order) based on all included experimental data. The best-performing model Aramco-2.0-2016 was further investigated by local sensitivity analysis. Several important reaction steps belonging to the hydrogen, syngas, and C1 systems were found to be important for all types of experiments, and furthermore reactions C2H3 + O2 = CH2CHO + O and C2H4 + OH = C2H3 + H2O which are specific for ethylene combustion.

The Mezaine-2022 reaction mechanism had the best performance, but the three versions of AramcoMech, the Burke-2016 and the Gong-2015 mechanisms also reproduced the experiments well. Local sensitivity analysis showed that the most important reactions of acetone combustion are the unimolecular decomposition of acetone molecule, CH3COCH3 = CH3CO + CH3 and its H abstraction reactions with small radicals. Besides, some reactions of the methyl radical had significant sensitivity.
