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 investigate theoretically and numerically the effect of polymer additives on two-
dimensional turbulence by means of a viscoelastic model. We provide compelling evidence …

We show that, at low inertia and large elasticity, shell models of viscoelastic fluids develop a
chaotic behaviour with properties similar to those of elastic turbulence. The low …

We report the scaling relations between the exponents of the power-law decays of kinetic
and elastic energies, pressure, as well as torque fluctuations in elastic turbulence (ET). The …

The flow of polymer solutions is examined in a flow geometry where a jet is used to inject the
viscoelastic solution into a cylindrical tube. We show that this geometry allows for the …

We numerically investigate the spatial and temporal statistical properties of a dilute polymer
solution in the elastic turbulence regime, ie, in the chaotic flow state occurring at vanishing …

The weakly nonlinear dynamics of large-scale perturbations in a viscoelastic flow is
investigated both analytically, via asymptotic methods, and numerically. For sufficiently 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 …

Elastic turbulence is the chaotic fluid motion resulting from elastic instabilities due to the
addition of polymers in small concentrations at very small Reynolds (Re) numbers. Our …
