Two-dimensional elastic turbulence
S. Berti, A. Bistagnino, G. Boffetta +2
We investigate the effect of polymer additives on a two-dimensional Kolmogorov flow at very low Reynolds numbers by direct numerical simulations of the Oldroyd-B viscoelastic model…
Single particle Lagrangian dispersion in Bolgiano turbulence
A. Bistagnino, G. Boffetta, A. Mazzino
Single-particle dispersion in the Bolgiano--Obukhov regime of two-dimensional turbulent convection is investigated. Unlike dispersion in a flow displaying the classical K41 phenome…
Small scale statistics of viscoelastic turbulence
S. Berti, A. Bistagnino, G. Boffetta +2
The small scale statistics of homogeneous isotropic turbulence of dilute polymer solutions is investigated by means of direct numerical simulations of a simplified viscoelastic flu…
Nonlinear dynamics of the viscoelastic Kolmogorov flow
A. Bistagnino, G. Boffetta, A. Celani +3
The weakly nonlinear regime of a viscoelastic Navier--Stokes fluid is investigated. For the purely hydrodynamic case, it is known that large-scale perturbations tend to the minima…
