For the development and design of supercritical pressure water-cooled reactor (SCWR), it is necessary to accurately estimate heat transfer to supercritical pressure water in high bulk enthalpy region. In this study, heat transfer experiments were performed using supercritical pressure HCFC22 as a test fluid, which flowed upward in a uniformly heated vertical circular tube. The experimental data are compared with conventional heat transfer correlations. In addition, numerical simulations were performed with the k- model using the commercial CFD code STAR-CD to quantitatively reproduce the experimental data and to examine the effect of property variation on heat transfer.
