  A novel turbulence control strategy for wall-bounded shear flow is proposed
by Chagelishvili et al, 2014. The essence of this strategy involves
continuously imposition of specially designed seed velocity perturbations with
spanwise asymmetry near the flow wall. The configuration of this imposed
velocity field, enhanced due to the shear flow non-normality, breaks the flow
spanwise reflection symmetry, specifically, resulting in the generation of a
secondary nonuniform spanwise mean flow. Consequently, this secondary flow
significantly reduces flow turbulence. In Chagelishvili et al, 2014, the first
steps were taken towards developing this new turbulence control strategy and
demonstrating its efficiency. The plane Couette flow was considered, as a
representative example, and a theoretical and hypothetical weak near-wall
volume forcing was designed, which though theoretical, provided valuable
insights into the characteristics of the seed velocity field. Obviously, the
practical significance of this control strategy should be confirmed by
evaluating its effectiveness in flows at various Reynolds numbers, and with
different parameters of the imposed seed velocity field. In this paper, we
investigate the effectiveness and universality of the turbulence control
strategy for Couette flow at various Reynolds numbers and different locations
of the volume forcing. Through direct numerical simulations, we show
universality of the discussed turbulence control method. The application of a
specially designed, weak near-wall volume forcing with a fixed configuration
and amplitude results in the same effective turbulence control, reducing
turbulence kinetic energy production by 30-40\% across a wider range Reynolds
numbers, $Re_{\tau} = 52,92,128,270$ and various localizations.
