The turbulent energy cascade in dilute polymers solution is addressed here by considering
a direct numerical simulation of homogeneous isotropic turbulence of a FENE-P fluid in a …

The modification of the turbulent cascade by polymeric additives is addressed by direct
numerical simulations of homogeneous isotropic turbulence of a FENE-P fluid. According to …

We use direct numerical simulations to study homogeneous and isotropic turbulent flows of
dilute polymer solutions at high Reynolds and Deborah numbers. We find that for small …

Direct numerical simulations of statistically steady homogeneous isotropic turbulence in
viscoelastic fluids described by the FENE-P model, such as those laden with polymers, are …

The paper addresses a set of new equations concerning the scale-by-scale balance of
turbulent fluctuations in dilute polymer solutions. The main difficulty is the energy associated …

The small-scale statistics of homogeneous isotropic turbulence of dilute polymer solutions is
investigated by means of direct numerical simulations of a simplified viscoelastic fluid model …

The comparison of the results of direct numerical simulations of isotropic turbulence of
Newtonian and viscoelastic fluid provides evidence that viscoelasticity modifies qualitatively …

We present results from a systematic numerical study of decaying turbulence in a dilute
polymer solution by using a shell-model version of the finitely extensible nonlinear elastic …

Direct numerical simulations of statistically steady homogeneous isotropic turbulence in
viscoelastic fluids described by the FENE-P model are presented. Emphasis is given to large …

By tracking small particles in the bulk of an intensely turbulent laboratory flow, we study the
effect of long-chain polymers on the Eulerian structure functions. We find that the structure …
