The turbulence of a realistic dilute solution DNA macromolecules is investigated through hybrid Eulerian–Lagrangian approach that directly solves the incompressible Navier–Stokes equation alongside evolution 108 polymers, modelled as finitely extensible nonlinear elastic (FENE) dumbbells. At friction Reynolds number 320 and Weissenberg 2×104, drag reduction equal to 26%, which similar one obtai...
