  bibo_abstract:
  - Based on a novel control scheme, where a steady modification of the streamwise
    velocity profile leads to complete relaminarization of initially fully turbulent
    pipe flow, we investigate the applicability and usefulness of custom-shaped honeycombs
    for such control. The custom-shaped honeycombs are used as stationary flow management
    devices which generate specific modifications of the streamwise velocity profile.
    Stereoscopic particle image velocimetry and pressure drop measurements are used
    to investigate and capture the development of the relaminarizing flow downstream
    these devices. We compare the performance of straight (constant length across
    the radius of the pipe) honeycombs with custom-shaped ones (variable length across
    the radius) and try to determine the optimal shape for maximal relaminarization
    at minimal pressure loss. The optimally modified streamwise velocity profile is
    found to be M-shaped, and the maximum attainable Reynolds number for total relaminarization
    is found to be of the order of 10,000. Consequently, the respective reduction
    in skin friction downstream of the device is almost by a factor of 5. The break-even
    point, where the additional pressure drop caused by the device is balanced by
    the savings due to relaminarization and a net gain is obtained, corresponds to
    a downstream stretch of distances as low as approximately 100 pipe diameters of
    laminar flow.@eng
