| Outline of Final Research Achievements |
Validations of detailed chemical kinetics are attempted for 1) CH4/oxidizer mixtures outside of its flammability limit and 2) flame retardant HFC refrigerants which are capable for reproducing their ignition and combustion characteristics. Original inhouse method termed “micro flow reactor with controlled temperature profile” was applied for 1) and 2) and experimental and computational investigations were conducted. For 1), validation of the methane kinetics with Xe and Kr dilutions which were used for analyzing microgravity experiments on combustion limits were achieved. For 2), understandings of reaction process of HFC refrigerants were achieved. Continuous research on 2) is aiming for the measurements of Fluoride intermediates and products.
