“…During the past decades, the combustion properties for a wide range of jet fuels, including widely used Jet A, JP-10, JP-8, Jet-A POSF 4658, and alternative kerosene, have been experimentally studied. 3 − 15 The ignition, extinction, flame speed, and species profiles were measured, covering a wide range of combustion conditions. Detailed chemical kinetic mechanisms for these fuels were also developed and validated by the traditional fuel surrogate approach, which employs several representative hydrocarbon compounds and the corresponding detailed kinetic mechanisms to mimic the physical and combustion properties of real fuels.…”

A single-pulse shock tube study of the pyrolysis of two different concentrations of Chinese RP-3 jet fuel at 5 bar in the temperature range of 900–1800 K has been performed in this work. Major intermediates are obtained and quantified using gas chromatography analysis. A flame-ionization detector and a thermal conductivity detector are used for species identification and quantification. Ethylene is the most abundant product in the pyrolysis process. Other important intermediates such as methane, ethane, propyne, acetylene, butene, and benzene are also identified and quantified. Kinetic modeling is performed using several detailed, semidetailed, and lumped mechanisms. It is found that the predictions for the major species such as ethylene, propene, and methane are acceptable. However, current kinetic mechanisms still need refinement for some important species. Different kinetic mechanisms exhibit very different performance in the prediction of certain species during the pyrolysis process. The rate of production (ROP) is carried out to compare the differences among these mechanisms and to identify major reaction pathways to the formation and consumption of the important species, and the results indicate that further studies on the thermal decomposition of 1,3-butadiene are needed to optimize kinetic models. The experimental data are expected to contribute to a database for the validation of mechanisms under pyrolytic conditions for RP-3 jet fuel and should also be valuable to a better understanding of the combustion behavior of RP-3 jet fuel.

“…Consequently, profiles of products and ignition delay times in oxidation models of various hydrocarbons were found to be highly sensitive to the kinetics of the abstraction reaction RH + HO 2 → R • + H 2 O 2 . 8,9 Despite being highly transient species, sophisticated experimental techniques provided direct identification and quantification of HO 2 radicals under atmospheric and combustion conditions. 10,11 Profiles of HO 2 radicals were qualitatively measured during oxidation of dimethylether 12 n-butane 13 deploying optical approaches encompassing midinfrared Faraday rotation spectroscopy and fluorescence assay by gas expansion (FAGE), respectively.…”

Ignition delay times of primary alcohols often display a noticeable sensitivity to their initial reactions with HO 2 radicals. In view of the transient nature of HO 2 radicals, kinetic models on combustion of alcohols utilize theoretically obtained constant parameters for the abstraction HO 2 + alcohols reactions. Rate constants for the title reactions in pertinent kinetic models are often extrapolated from analogous computed values for either alkanes + HO 2 or n-butane + HO 2 reactions. Even for the simplest alcohol, methanol, literature values for the reaction rate constants considerably vary within one order of magnitude. Herein, we compute reaction rate constants for H abstraction from the weakest sites in primary C 1−5 alcohols by HO 2 (methanol, ethanol, n-propanol, i-propanol, n-butanol, i-butanol, t-butanol, n-pentanol, and i-pentanol). In most cases, our reaction rate coefficients tend to slightly exceed corresponding values deployed in pertinent kinetic models. We have thoroughly assessed the predictive performance of literature kinetic models in computing ignition delay times of these alcohols based on the updated rate constants for HO 2 -abstraction reactions. In the case of methanol, updating kinetic parameters for the reaction CH 3 OH + HO 2 → CH 2 OH + H 2 O 2 improves prediction of ignition delay times at lower temperatures in reference to original literature kinetic models. Likewise, a modified kinetic model for n-butane and t-butanol affords better agreement with experimental values of ignition delay times at low temperatures and high pressures. Kinetic parameters presented herein will be useful to accurately account for salient oxidation features of alcohols in real combustion engines.

RP-3 kerosene is the most widely used aviation kerosene in China, and research on its chemical-kinetic mechanism is significant for understanding the combustion characteristics. Based on a novel four-component surrogate fuel consisting of n -dodecane, 2,5-dimethylhexane, 1,3,5-trimethylbenzene, and decalin (54, 22, 14, and 10% by mole), the detailed chemical-kinetic mechanism of the corresponding RP-3 surrogate fuel with 1333 species and 6803 reactions has been developed and then reduced to 145 species and 818 reactions for high-temperature conditions. After that, the merged surrogate mechanism of surrogate fuel was validated by various experimental data sets for each individual surrogate component. Then, the surrogate mechanism was validated by comparing the simulation and experimental data of the ignition delay times, species concentrations in a jet-stirred reactor, and laminar flame speeds. Good agreements between simulations and experiments were observed. In addition, using the sensitivity analysis method, the key reactions of RP-3 surrogate fuels were compared and analyzed. In summary, the mechanism developed in this study can accurately predict the ignition, oxidation, and flame propagation characteristics of RP-3 aviation kerosene. The novel surrogate model can help deeply understand the combustion characteristics of RP-3 aviation kerosene, and it is used for high-precision numerical simulation of combustion reaction flow.
