| Outline of Final Research Achievements |
In this study, simultaneous measurement of heat transport rate and internal flow pattern was performed for two different heat transport devices: Parallel-Tube Heat Transport Device (PTH) and Oscillating Heat Pipe (OHP). The purpose was to obtain quantitative internal flow information that could be benchmark data in numerical calculation. The internal flow patterns were captured by using a high-speed camera, and the temporally and spatially changing of flow patterns were identified by laterally averaged brightness of the captured images. From this analysis results, the internal-flow characteristics: appearance ratio of flow patterns, gas-liquid interfacial velocity, the number of interfaces, and the characteristic frequency of internal flow could be calculated in this study. These can become benchmark data usable for future development of the numerical models and this type of quantitative data has not been supplied in the open literature.
