Cover Story: Turbulent pipe flow laden with realistic DNA macromolecules is investigated through a hybrid Eulerian–Lagrangian approach solving the incompressible Navier–Stokes equation alongside the evolution of 108 polymer dumbbells. Such an innovative approach comes in line with a current trend of numerical simulations that move toward the “first-principles”-like methods and bring more detailed and accurate descriptions of the physical phenomena. A drag reduction of 26% is achieved at friction Reynolds number 320 and Weissenberg number 20,000. An increase in the flow rate and turbulent kinetic energy is observed. Near the wall, the majority of the polymers are fully stretched and aligned along the streamwise direction, inducing an increase in the turbulence anisotropy. View this paper
