Detailed And Compact Combustion Kinetic Models For Iso-Dodecane And Gevo Alcohol-To-Jet (Atj) Alternative Fuel, Francis M. Haas, Sang Hee Won, Frederick L. Dryer
Francis (Mac) Haas
Over a broad range of conditions and experimental configurations, recent experimental work has shown quantitative similarities between the pre-vaporized combustion behaviors of iso-dodecane (iC12: 2,2,4,6,6-pentamethylheptane), iso-octane (iC8: 2,2,4-trimethylpentane), iso-cetane (iC16: 2,2,4,4,6,8,8-heptamethylnonane), and a 50/50 (molar) iC8/iC16 mixture. Such similarity – typically within experimental uncertainties – suggests that these fuels share a significant subset of combustion chemistry related to fuel destruction into nearly equal fluxes of iso-C4 fragments. This proposition is used to develop a compact (43 species) kinetic model to describe iC12 combustion by using detailed chemistry models for iC16 and iC8, since at present, no detailed iC12 oxidation model …
