Kinetic Modeling of the Impact of n-Decane Aging on its Combustion Characteristics
Résumé
In current aircrafts, jet fuels are used as coolants and their oxidation in the liquid phase (autoxidation) occurs before their combustion. Autoxidation changes the fuel composition and its physical properties. Despite its ubiquity, the effects of fuel autoxidation on its combustion characteristics remain unexplored in the literature. In this work, two validated detailed kinetic models for n-decane autoxidation and combustion are developed and used to explore these phenomena. Fuel autoxidation has a strong impact on ignition delays, fuel conversion and oxygenated combustion products because of hydroperoxides and alcohols formed during liquid phase oxidation.
