Effect of viscoelasticity on the small scale statistics of homogeneous isotropic turbulence

Abstract eng:
The comparison of the results of direct numerical simulations (DNS) of homogeneous and isotropic turbulence (HIT) of viscoelastic fluid are done based on the FENE-P model. It provides evidence, comparing with DNS of Newtonian fluid HIT, that viscoelasticity modifies qualitatively the behaviour of the smallest scales.
