Abstract
The effect of rheological parameters on the drag-reduction by surfactant additives is studied with a viscoelastic Giesekus model. It is found that the streamwise vorticity becomes much weaker and more elongated with the increase of large drag-reduction rates. The modifications of streamwise vorticity are given. The alteration of the energy cascade process is discussed.
