摘要:
A direct numerical simulation of fully developed turbulent plane Couette flow has been performed. Unsteady large-scale structures, which contributed to the instantaneous energy level, were observed. These evolving and drifting vortical structures vanished after time-averaging, and the resulting mean velocity and streamwise turbulence intensity compared favourably with recent laboratory data.
