abstract = {<p style="text-align: justify;">The turbulence in plane Couette flow subjected to system rotation is investigated.
The anti-cyclonic rotation rate is well above the range in which roll-cells occur
and close to the upper bound, beyond which no stationary turbulent states of motion
exist. The mean velocity profile exhibits a linear region over 80% of the cross-section, in
which the mean absolute vorticity is driven to zero. Viscous effects still prevail in narrow
regions next to the walls, whereas the quasi-homogeneous central core exhibits
abnormal anisotropies of the Reynolds stress tensor, the vorticity tensor and the energy
dissipation rate tensor. In spite of the distinctly higher turbulence level observed,
a 13% drag reduction is found. This paradoxical finding is ascribed to configurational
changes in the turbulence field brought about by the system rotation.</p>},
