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 40 atm and constant residence time, over the high temperature range 800-1300 K, and for variable equivalence ratio 0.5 < rho < 2. Concentration profiles of 1 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-decanen-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 front the literature.
