000014958 520__ $$2eng$$aThe role of Elasto-Inertial Turbulence (EIT) on the bounds of friction drag is investigated in channel flows from subcritical to moderate Reynolds numbers. EIT is a newly discovered state of turbulence emerging from self-sustaining interactions between polymer dynamics and velocity perturbations in parallel shear flows. At low Reynolds numbers, EIT creates an increase in friction drag. Beyond the critical Reynolds number for Newtonian flows, EIT becomes the lower bound of the friction drag of the Maximum Drag Reduction (MDR) state. The drag reduction properties of polymer control the upper bound of MDR.
