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 (5 lambda) 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 (7 lambda) 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 mu m, 10.958 mu m, and 11.345 mu m. Simulations using two recent models are compared to the experimental data and the discrepancies are examined. (C) 2019 The Combustion Institute. Published by Elsevier Inc. All rights reserved.
