Development of Comprehensive Detailed and Reduced Reaction Mechanisms for Syngas and Hydrogen Combustion
- Case Western Reserve University
The collaborative research initiative culminated in amassing a substantial combustion database of experimental results for dry and moist mixtures of syngas and hydrogen (SGH), including autoignition times using a rapid compression machine as well as laminar flame speeds using a counterflow twin-flame configuration. These experimental data provided the basis for assessment of the kinetics of SGH combustion at elevated pressures using global uncertainty analysis methods. A review of the fundamental combustion characteristics of H{sub 2}/CO mixtures, with emphasis on ignition and flame propagation at high pressures was also conducted to understand the state of the art in SGH combustion. Investigation of the reaction kinetics of CO+HO{sub 2}{center_dot} {yields} CO{sub 2} + {center_dot}OH and HO{sub 2}+OH {yields} H{sub 2}O+O{sub 2} by ab initio calculations and master equation modeling was further carried out in order to look into the discrepancies between the experimental data and the results predicted by the mechanisms.
