text: Flows through pipes and channels are the most common means to transport fluids
in practical applications and equally occur in numerous natural systems. In general,
the transfer of fluids is energetically far more efficient if the motion is smooth
and laminar because the friction losses are lower. However, even at moderate velocities
pipe and channel flows are sensitive to minute disturbances, and in practice most
flows are turbulent. Investigating the motion and spatial distribution of vortices,
we uncovered an amplification mechanism that constantly feeds energy from the
mean shear into turbulent eddies. At intermediate flow rates, a simple control
mechanism suffices to intercept this energy transfer by reducing inflection points
in the velocity profile. When activated, an immediate collapse of turbulence is
observed, and the flow relaminarizes.
