内容記述 | Direct numerical simulation of a fully developed turbulent channel flow has been carried out using new NS system at NAL. The Reynolds numbers are set to be Re(sub tau) = 180 and 1,020, where Re(sub tau) is the Reynolds number based on the friction velocity and the channel half width. To the present knowledge, DNS for Re(sub tau) = 1,020 is one of the largest computations ever simulated in conjunction with this configuration, where about 1.4 billion grid points are required to resolve all the eddies. In the present study, the Reynolds-number dependence on turbulence statistics is investigated up to Re(sub tau) = 1,020. Moreover, turbulence structures for Re(sub tau) = 1,020 are visualized in order to examine the characteristics of quasi-coherent structures such as high and low-speed streaks and vortices. | |||||
