The objective of this research is to reveal the forced convection heat transfer both in the sub-and super-critical regions near the critical point. In these regions, physical properties strongly depend on both the pressure and temperature, so that characteristics of fluid flow and heat transfer is more complicated than those for lower pressure. The study in the supercritical region relates to the new technology, which applies the supercritical pressure water to the boiling-water nuclear reactor. The other study in the subcritical region, where boiling takes place, aims to obtain the acquisition of design data of the evaporator in the refrigeration using carbon dioxide as a natural refrigerant. The heating experiment was performed for forced convection in the horizontal smooth tube with 2mm inner diameter. And heat transfer coefficient and pressure drop were measured and discussed in connection of variation of the property.
