Comprehensive mechanisms for combustion chemistry: An experimental and numerical study with emphasis on applied sensitivity analysis. Progress report, June 15, 1990--February 1, 1993

摘要

Over the last three years, this program has made significant progress on a number of problems: development of a data base for oxidation of the CO/H(sub 2)/O(sub 2) system; development and refinement of a comprehensive kinetic mechanism for the CO/H(sub 2)/O(sub 2) system; additional experiments on formaldehyde oxidation in the, comprehensive mechanistic studies inclusive of flow reactor results and literature results from static reactors, shock tubes, and flames, and identification of elementary reactions needing further study; mechanistic study of previously acquired APFR flow reactor data on ethanol oxidation, including an estimation of the branching ratios for C(sub 2)H(sub 5)0H + X, X= OH,H and identification of elementary reactions needing additional study; completion and mechanistic evaluation of the first insitu optical diapostic measurements of OH in the APFR; determinations of uni-molecular decomposition rate for 1,3,5-Trioxane at 700 to 800 K; seeded perturbation experiments on moist CO oxidation in flow reactors as a means to determine elementary rate constants for specific reactions; determination of elementary rates for CH(sub 4) + OH (yields) CH(sub 3) + H(sub 2)0 at 1026 and 1140 K, and C(sub 3)H(sub 6) + OH (yields) products at 1020 K; First experimental studies of the H(sub 2)/O(sub 2) reaction system in the VPFR at conditions between the extended second and third explosion limits.
