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

Abstract : 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.
