| 内容記述 | It is important to investigate the characteristics of thermofluids for cooling blankets and divertors used in the high-temperature plasma of fusion reactors. Various coolant materials on the cooling problem such as a fusion reactor were widely considered from FLiBe to lithium. In the present study, we proposed pressurized water as the working fluid for the blanket design. We performed direct numerical simulation of pipe flow with Reynolds number of 2100 based on the pipe radius and friction velocity. The number of mesh points used were 4096 × 1024 × 1532 in the z−, r−, and φ-directions, respectively. The Prandtl number of pressurized water was set as 0.87. The results show that compared with air as a general coolant material, pressurized water has higher turbulent heat transfer. | |||||
