摘要：
To get more insight into the physical mechanism of elastic turbulence, 3D, time-dependent direct numerical simulations (DNS) based on finitely extensible nonlinear extension Perlin (FENE-P) constitutive model were carried out for 3D Kolmogorov flow with polymer additives. In the present paper, the characteristics of the vortex structures, including its genertation and evolution in the elastic turbulent flow, were investigated through visualization and analyses of the enstrophy and strain transport equations.
