The overall reaction rate for JP10 + OH → products was measured directly via laser absorption of OH in shock tube experiments from 931 to 1308 K and 0.94 to 1.44 atm. The JP10 concentration of test gas mixtures was measured in the shock tube for several experiments using a 3.39 μm laser fuel diagnostic. The measured JP10 concentrations indicated fuel losses due to adsorption of 11–31% compared to values calculated manometrically from mixture preparation. OH was generated via rapid thermal decomposition of tert-butyl hydroperoxide behind reflected shock waves, and post-shock OH profiles were measured via laser absorption at 308.6 nm. The measured OH profiles were fit with a chemical kinetic model for JP10 chemistry to determine the overall JP10 + OH reaction rate. A recommendation is made for the JP10 + OH overall reaction rate over the temperature range explored in this study as k1(931–1308 K) = 1.622 × 1014exp(−1826/T[K]) ± 12%. To the authors’ knowledge, these data are the first direct measurements of the overall reaction rate for JP10 + OH. |
