Abstract

JP-10 is a high-energy-density liquid hydrocarbon fuel that has been used extensively in ramjet missile applications and is being considered as a fuel for 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 describe our efforts on developing a pressure dependent, detailed chemical kinetic mechanism that describes the combustion of JP-10. The mechanism is being developed through the use of 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 for ignition delay and species profiles and new data for species profiles developed within the project.
