Kinetics of Jet Fuel Combustion Over Extended Conditions: Experimental and Modeling

The oxidation of kerosene (Jet-A1) has been studied experimentally in a jet-stirred reactor at 1 to $40atm$ and constant residence time, over the high temperature range $800-1300K$⁠, and for variable equivalence ratio $0.5<φ<2$⁠. Concentration profiles of reactants, stable intermediates, and final products have been obtained by probe sampling followed by on-line and off-line GC analyses. The oxidation of kerosene in these conditions was modeled using a detailed kinetic reaction mechanism (209 species and 1673 reactions, most of them reversible). In the kinetic modeling, kerosene was represented by four surrogate model fuels: 100% $n$-decane, $n$-decane-$n$-propylbenzene $(74%∕26%mole)$⁠, $n$-decane-$n$-propylcyclohexane $(74%∕26%mole)$⁠, and $n$-decane-$n$-propylbenzene-$n$-propylcyclohexane $(74%∕15%∕11%mole)$⁠. The three-component model fuel was the most appropriate for simulating the JSR experiments. It was also successfully used to simulate the structure of a fuel-rich premixed kerosene-oxygen-nitrogen flame and ignition delays taken from the literature.
