Direct numerical simulation of a turbulent channel flow at Reτ 2320 was performed in order to examine the flow statistics, and the relationship between the near-wall and outer-layer structures. The number of the total grid points is about 16 billions, and the effective computational speed is about 5.5 TFLOPS by using 2048 CPUs and 4 TB main memory on the Earth Simulator. The mean velocity profi...
