Detailed Chemical-Kinetic Model for Aviation Fuels

Abstract

Theintroductionofdetailedchemicalreactionmechanismsforaviationfuelsintocomplexmultidimensionale uid dynamics problems is not practical at the present time. Simplie ed reaction mechanisms that have been thoroughly evaluated must be developed to address specie c issues arising in realistic combustor cone gurations. The latter should be e rmly based on detailed mechanisms carefully evaluated against a wide range of experimental data. A detailed kinetic mechanism for hydrocarbon combustion is formulated to address the gas-phase chemistry of endothermic and conventional aviation fuels. Reaction paths are analysed for n-decane and kerosene premixed e ames, and the ability ofthemechanism to predictvarious premixed e ame featuresisassessed by comparison with experimental species proe les. Finally, the level of success achieved by the present kinetic model in the context of practical problems is discussed.
