Abstract:

JP-8 and JP-10 are important aviation fuels used by the US military in turbine-powered aircraft and diesel-powered ground vehicles, and gas turbine fuel for missiles, respectively. JP-8 is a complex kerosene-based fuel mixture, while JP-10 is a newer synthetic fuel mixture containing endo-tetrahydrodicyclopentadiene, exo-tetrahydrodicyclopentadiene, and adamantane. In this study, the detonation of JP-8 and JP-10 mixtures was simulated to investigate the effects of JP-10 presence with JP-8 on detonation. The study analyzed the effects of different mixing ratios of JP-8/JP-10 at varying equivalence ratios. The results indicated that JP-10 is slightly slower in reactivity but has a higher heat and pressure generation capacity than JP-8. The maximum pressure and temperature were observed as 3.41 MPa and 2093 K, respectively, at 50/50% mixing of JP-8/JP-10 at  = 1.0. The maximum detonation propagation velocity was observed as 1988 m/s for 70%JP-8 + 30%JP-10. This study provides valuable insights into the behavior of JP-8 and JP-10 mixtures and their detonation characteristics, which can have important implications for the design and operation of aviation and missile systems.
