Abstract This work presents a novel application of multi-wavelength, multi-species laser absorption methods in the pyrolysis of JP-10 fuel. Two different multi wavelength approaches are used to measure the species from JP-10 pyrolysis in a shock tube at pressures of 2.5–3 atm and temperatures of 1166–1522 K. A five wavelength (5λ) analysis combination produces species time histories for ethylene, cyclopentadiene, and methane formation, as well as estimates of fuel decay. These results are extended further using a seven wavelength (7λ) combination of methods to measure ethylene, cyclopentadiene, propene, methane, allene, 1,3 butadiene, benzene, toluene, and fuel. Supplementary material includes details on the cyclopentadiene cross sections for 10.532 µm, 10.958 µm, and 11.345 µm. Simulations using two recent models are compared to the experimental data and the discrepancies are examined.

JP-10 燃料热解的冲击管/激光吸收测量

摘要 这项工作提出了多波长、多物种激光吸收方法在 JP-10 燃料热解中的新应用。两种不同的多波长方法用于在 2.5-3 个大气压的压力和 1166-1522 K 的温度下在激波管中测量来自 JP-10 热解的物质。五波长 (5λ) 分析组合产生乙烯的物质时间历程，环戊二烯和甲烷的形成，以及对燃料衰减的估计。使用七波长 (7λ) 组合方法进一步扩展了这些结果，以测量乙烯、环戊二烯、丙烯、甲烷、丙二烯、1,3 丁二烯、苯、甲苯和燃料。补充材料包括 10.532 µm、10.958 µm 和 11.345 µm 的环戊二烯横截面的详细信息。
