Inverse turbulent cascades and conformally invariant curves
D. Bernard, G. Boffetta, A. Celani +1
We offer a new example of conformal invariance far from equilibrium -- the inverse cascade of Surface Quasi-Geostrophic (SQG) turbulence. We show that temperature isolines are stat…
Dynamical Slowdown of Polymers in Laminar and Random Flows
Antonio Celani, Alberto Puliafito, Dario Vincenzi
The influence of an external flow on the relaxation dynamics of a single polymer is investigated theoretically and numerically. We show that a pronounced dynamical slowdown occurs…
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…
