Surrogate Fuel Analysis and Reduction using Computational Singular Perturbation

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.
