Direct numerical simulation of the turbulent heat transfer in a channel flow with changing various properties has been performed to obtain turbulence statistics of supercritical water. Moreover, the function of changing properties was also installed with a commercial code by using the knowledge obtained from Direct numerical simulation. The results lead to understand the flow phenomenon of supercritical water in the basic scientific field. In this study, it indicates the possible of contributing to the application to the coolant flow of the nuclear fusion reactor for power generation and the extraction separation technology of an effective substance.
