“… 2 Hence, many relevant studies have been performed by researchers to measure the basic combustion properties of jet fuels during the past decades. 3 − 9 Although jet fuels mainly consist of hydrocarbon compounds, the real components of jet fuels used in different countries are still different depending upon their origin oil resource, exploitation, and refining processes. The different compositions in jet fuels certainty affect the combustion properties.…”

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.

“…Also, rate of production (ROP) and sensitivity analyses were used to identify the dominant consumption pathways of furfural. Furthermore, reaction rate expressions of major initiation reactions within furfural consumption have been determined by applying quantum chemical calculations, at CBS-QB3 level found to be appropriate for these types of fuels [29][30][31][32].…”

“…While other literature works discuss the development and validation of fuel surrogates and models for specific fuels (Dooley et al, 2010;Kim et al, 2014;Liu et al, 2019;Prak et al, 2022), this paper focuses on the methodological aspects involved in the definition of general models aiming at capturing fundamental aspects of the fuel chemistry. In this work, combustion chemistry models for three highly diverse fuels are obtained by coupling a single comprehensive kinetic mechanism and a surrogate formulation approach incorporating compositional information.…”

This work analyses, experimentally and numerically, the combustion behavior of three aviation fuels: a standard Jet A-1, a high aromatic content fuel, and an isoparaffinic Alcohol to Jet (ATJ) fuel. The goal is to demonstrate the ability of a chemical kinetic model to capture the chemistry underlying the combustion behavior of a wide range of jet fuels, starting from compositional information. Real fuels containing up to hundreds of components are modeled as surrogates containing less than 10 components, which represent the chemical functionalities of the real fuel. By using an in-house numerical optimizer, the fuel components and their relative quantities are selected, and a semi-detailed kinetic model (containing about 450 species) is used to simulate the formation of the main oxidation products and reaction intermediates. Calculations are compared with species profiles measured in a laminar flow reactor to validate the model and provide insights into the reactivity of the fuels. Finally, starting from the results, general observations on the strengths and limits of the approach are provided, highlighting areas where further investigations are required.
