Drag reduction in homogeneous shear flow turbulence diluted with contravariant and covariant polymers

This study conducts a multi-scale analysis on the drag reduction (DR) in the fluid flow diluted with the polymers. A mesoscopic description of ensemble of elastic dumbbells using Brownian dynamics (BDS) is connected to the macroscopic description for the solvent Newtonian fluid using DNS [1]. In Horiuti \etal [2], non-affinity in which the...
