| Outline of Final Research Achievements |
In this study, a method to measure the temperature jump in the slip flow regime was studied, and characteristics of the temperature jump coefficient for gas mixtures as a function of the molar ratio was investigated. The concentric spherical shells geometry was employed for the measurement; however, it was hard to explain measured values theoretically. Therefore, the heat transfer in the apparatus was studied in detail, and a measurement system with the coaxial cylinders geometry was constructed. The thermal accommodation coefficients for gas mixtures were measured, and characteristics of the temperature jump coefficient were estimated.
