| Outline of Final Research Achievements |
In this study, the flow characteristics of water molecules in the micro-scale flow field was investigated. The mass flow rate through a micro channel was experimentally measured and the tangential momentum accommodation coefficient, which represents the gas-surface interaction, was extracted. The result indicated that water molecules have different characteristics from monatomic noble gases. The effect of gas mixture was also investigated and it was clarified that the flow characteristics are affected by the molar ratio of the mixture.
