  bibo_abstract:
  - Creeping flow of polymeric fluid without inertia exhibits elastic instabilities
    and elastic turbulence accompanied by drag enhancement due to elastic stress produced
    by flow-stretched polymers. However, in inertia-dominated flow at high Re and
    low fluid elasticity El, a reduction in turbulent frictional drag is caused by
    an intricate competition between inertial and elastic stresses. Here we explore
    the effect of inertia on the stability of viscoelastic flow in a broad range of
    control parameters El and (Re,Wi). We present the stability diagram of observed
    flow regimes in Wi-Re coordinates and find that the instabilities' onsets show
    an unexpectedly nonmonotonic dependence on El. Further, three distinct regions
    in the diagram are identified based on El. Strikingly, for high-elasticity fluids
    we discover a complete relaminarization of flow at Reynolds number in the range
    of 1 to 10, different from a well-known turbulent drag reduction. These counterintuitive
    effects may be explained by a finite polymer extensibility and a suppression of
    vorticity at high Wi. Our results call for further theoretical and numerical development
    to uncover the role of inertial effect on elastic turbulence in a viscoelastic
    flow.@eng
