Laminar burning velocities of propionic acid + air flames : Experimental, modeling and data consistency study
(2021) In Combustion and Flame 230.- Abstract
Laminar burning velocities of propionic acid + air flames have been determined using the heat flux method at atmospheric pressure and initial gas mixture temperature of 348 K over the range of equivalence ratios 0.7–1.3. The detailed kinetic model of the authors was extended by the reactions of propionic acid and its intermediates. Attention has been paid to the proper description of the formation and consumption of 1,1-propenediol, methyl ketene, and acrylic acid. New experimental results have been compared with the modelling using this kinetic mechanism and the mechanism of Zhang et al. (2021). The comparison of the new and available from the literature measurements obtained at different initial temperatures with predictions of the... (More)

Attention has been paid to the proper description of the formation and consumption of 1,1-propenediol, methyl ketene, and acrylic acid. New experimental results have been compared with the modelling using this kinetic mechanism and the mechanism of Zhang et al. (2021). The comparison of the new and available from the literature measurements obtained at different initial temperatures with predictions of the two models allowed for analysis of the data consistency for the burning velocities of propionic acid, as well as for acetic and formic acids. Inconsistencies of some datasets for these short-chain carboxylic acids were identified and discussed.
