Abstract
Direct numerical simulation of a spectral method was performed to study the relaminarization process of the plane Couette flows under spanwise system rotation. As increasing the rotational effect, large-scale intermittency of the turbulence appear in the near wall region. Then the turbulent stripe consisting of the turbulent and quasi-laminar regions near the wall, while homogeneous turbulence was observed in the channel center. The small scale structure is almost same in the entire channel except wall vicinity consisting of viscous sub-layer and buffer layer. As increasing the rotational effect, turbulent spot was observed, though the homogeneous turbulence was observed in channel center. In the intermediate state, friction coefficient largely oscillates with time.
