B208マッハツェンダー干渉計による超臨界二酸化炭素流れの温度分布計測

抄録

For development of nuclear reacter or other boilers that use supercritical water, importance of experimental knowledge is increasing to investigate thermal characteristic of supercritical fluid, which is very peculiar. It is well known that there occurs heat transfer enhancement and deterioration in supercritical fluid, however, it is very hard to observe in a case of forced convection because of difficulties in high pressure and temperature. In this study, boiling-like phenomenon in forced convection heat transfer was observed by white-light illumination. Also dependency of boiling to physical parameters was examined. Moreover, Mach-Zehnder interferometer was also applied to investigate temperature distribution in the flow. Temperature variation around the heated wall was measured by interferogram.
