High-Performance Jet Fuels
Accurate and reliable chemical kinetic models for jet fuels are imperative for the development of high-efficiency jet engines and next-generation combustion strategies.
However, most detailed reaction mechanisms for distillate jet fuels – fuels composed of thousands of hydrocarbon species – are still preliminary or limited in their ability to predict the oxidation and pyrolysis behavior of real fuels. Our laboratory addresses this problem by providing the experimental basis for a novel Hybrid Chemistry (HyChem) modeling approach, developed in collaboration with Professor Hai Wang at Stanford [1,2]. Shock tubes combined with laser absorption diagnostics can furnish the kinetic targets (e.g., ignition delay times, oxidation and pyrolysis species time-histories, etc.) needed to validate and optimize key reaction pathways.
Other notable jet fuel studies conducted by our group include the first high-accuracy dataset of methane and ethylene formation during jet fuel pyrolysis , and observation of consistent auto-ignition behavior among different distillate fuel types (jet fuel, rocket propellant, kerosene, diesel, and gasoline) .
