Outline of Final Research Achievements

To verify the validity of the analytical model of the varying concentration phenomenon of refrigerant gas dissolved in the lubricating film, the systems for measuring the refrigerant concentration distribution dissolved in the thickness direction in the lubricating film were developed. This system consists of the concentration distribution measurement system combined a confocal microscope with a laser-induced fluorescence method and the lubricating film observation system under refrigerant gas atmosphere. The spatial resolution in the thickness direction of this system was confirmed to be comparable to the theoretical value.
