Abstract

We follow the simplification procedure described in previous work to generate simplified kinetic mechanisms for the surrogate fuel proposed by Dagaut for jet fuels. A family of comprehensive mechanisms is produced at different pressures (1, 10, 20, and 40 atm) by analyzing the constant volume, adiabatic, spatially homogeneous, auto-ignition process of surrogate/air mixture at different equivalence ratios and initial temperatures. We identify the prevailing pathways of surrogate oxidation for low and high temperature kinetics for a lean mixture at 10 atm. We assess how the accuracy of the prediction of soot precursors changes with different choices of the set of target species.
