Forced convection heat transfer and boiling-like phenomena of carbon dioxide fluid at supercritical pressure has been measured by visualization technique. For nuclear reacter that use supercritical water, it is important to investigate thermal characteristic of supercritical fluid, which is very peculiar. There occurs heat transfer enhancement and deterioration in supercritical fluid, however, it is hardly observed in a case of forced convection. 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 confirmed. Mach-Zehnder interferometer was also applied to investigate temperature distribution in the flow. Temperature variation around the heated wall was measured by interferogram.
