ABSTRAKT

Numerical simulation of a drag-reducing turbulent channel flow due to polymer is performed. The beads-spring-dashpot chain model is employed as a model of polymer. The model consists of beads, springs, and dashpot to represent polymer dynamics. Energy exchange between the polymer and the fluid is mainly focused to discuss the drag-reduction mechanism. Results show that the energy transport by the polymer models enhances the streamwise velocity fluctuation and strengthen the turbulence anisotropy.
