--- _id: '2798' abstract: - lang: eng 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. author: - first_name: Björn full_name: Björn Hof id: 3A374330-F248-11E8-B48F-1D18A9856A87 last_name: Hof orcid: 0000-0003-2057-2754 - first_name: Alberto full_name: de Lózar, Alberto last_name: De Lózar - first_name: Marc full_name: Avila, Marc last_name: Avila - first_name: Xiaoyun full_name: Xiaoyun Tu id: 2AFD1610-F248-11E8-B48F-1D18A9856A87 last_name: Tu - first_name: Tobias full_name: Schneider, Tobias M last_name: Schneider citation: ama: Hof B, De Lózar A, Avila M, Tu X, Schneider T.
