JP-10 is a high-energy-density liquid hydrocarbon fuel that has been used extensively in ramjet missile applications and is being considered for use in SCRAMJET, pulse detonation engines and Unmanned Aerial Vehicles (UAVs). These applications involve a broad range of pressures. A validated and reliable JP-10 kinetics model would be useful for assessing air-breathing propulsion flow-path performance and would facilitate the design of improved combustion systems. In this paper we highlight a pressure dependent, detailed chemical kinetic mechanism that describes the combustion of JP-10. Funding is being provided through a Navy STTR Phase II project (NAVAIR contract = N68335-10-C-0470). The mechanism is being developed using dynamic trajectory analysis to identify potential reaction pathways, ab-initio chemistry calculations to determine thermochemical properties and kinetic rates, and ab-initio chemistry and group additivity theory to calculate transport properties. Provided are comparisons of predicted and measured values from the literature and for new data.
