| Outline of Final Research Achievements |
To construct the comprehensive reaction model that can predict hydrogen explosion and ignition, ignition induction periods were measured in a high-pressure shock tube and a rapid compression machine. Based on these experimental data, the reaction model for the hydrogen explosion and ignition was optimized in the wide pressure and temperature ranges. The additive effects of hydrocarbons, such as methane and ethane, on hydrogen ignition were investigated in the shock tube. These hydrocarbons inhibited the hydrogen ignition, because they captured the hydrogen atoms that were important chain carriers in the hydrogen oxidation reactions.
