Abstract:

A framework for the study of high-temperature hydrocarbon pyrolysis is presented. The proposed frame- work details a multi-wavelength speciation method using convex optimization, a review of complementary fixed-wavelength laser diagnostics, and a database of high-temperature absorption cross-sections to enable use of the framework for 11 different species. The proposed speciation method involves a vectorized Beer-Lambert system solved under solution constraints using convex optimization. In support of the proposed method, a review of pertinent laser diagnostics and a database of high-temperature absorption cross-sections are also provided. The database includes measured absorption cross-sections of methane (CH 4 ), ethylene (C 2 H 4 ), propene (C 3 H 6 ), isobutene (i-C 4 H 8 ), 1-butene (1-C 4 H 8 ), benzene (C 6 H 6 ), toluene (C 7 H 8 ), and four jet fuels (samples of Jet A, JP5, JP8, and Gevo ATJ) at the wavelengths of 3.1758 μm, 3.17595 μm, 3.283 μm, 3.392 μm, 3.410 μm, 10.532 μm, 10.675 μm, 10.89 μm, 10.958 μm, 10.962 μm, and 11.345 μm within the range of 30 0–160 0 K and 0.25–4 atm. The database is comprised of over 10 0 0 high–temperature absorption cross-section measurements from new shock tube experiments, new Fourier transform infrared spectrometer (FTIR) experiments, and an aggregated dataset from the literature. The convex speciation method and cross-section database provided will facilitate laser absorption studies of hydrocarbon pyrolysis used in the development of chemical kinetic mechanisms.
