Abstract
Direct numerical simulations (DNSs) of the fully developed turbulent flow between two parallel walls driven by a combination of a mean pressure gradient and the streamwise movement of one of the walls, i. e., turbulent Couette-Poiseuille flow, were carried out. The mean velocity gradient on the moving wall was reduced from that of an ordinary Poiseuille-type flow to almost zero. The turbulence statistics including the stress anisotropy and the budgets of the turbulence energy and Reynolds stresses are presented. The instantaneous flow fields visualized reveal that the structure of the near-wall turbulence under a weak mean shear does not exhibit any elongated streaks and is much different from that of the sheared wall layers.
