摘要：

In this article, a second order finite difference scheme was employed for the DNS study of the drag-reducing Gieselcus fluid flow in a two-dimensional channel. A second-order bounded scheme, MINMOD, was used to discretize the convective term in the constitutive equation. The instantaneous stress and flow structures at different Weissenberg numbers are compared. Effects of Weissenberg number on various turbulence statistics such as turbulence intensities, Reynolds shear stress and two-point correlation coefficients are also presented.
