  text: The dissolution of minute concentration of polymers in wall-bounded flows
    is well-known for its unparalleled ability to reduce turbulent friction drag.
    Another phenomenon, elasto-inertial turbulence (EIT), has been far less studied
    even though elastic instabilities have already been observed in dilute polymer
    solutions before the discovery of polymer drag reduction. EIT is a chaotic state
    driven by polymer dynamics that is observed across many orders of magnitude in
    Reynolds number. It involves energy transfer from small elastic scales to large
    flow scales. The investigation of the mechanisms of EIT offers the possibility
    to better understand other complex phenomena such as elastic turbulence and maximum
    drag reduction. In this review, we survey recent research efforts that are advancing
    the understanding of the dynamics of EIT. We highlight the fundamental differences
    between EIT and Newtonian/inertial turbulence from the perspective of experiments,
    numerical simulations, instabilities, and coherent structures. Finally, we discuss
    the possible links between EIT and elastic turbulence and polymer drag reduction,
    as well as the remaining challenges in unraveling the self-sustaining mechanism
    of EIT.
