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…
Influence of helicity on anomalous scaling of a passive scalar advected by the turbulent velocity field with finite correlation time: Two-loop approximation
O. G. Chkhetiani, M. Hnatič, E. Jurcisinova +3
The influence of helicity on the stability of scaling regimes, on the effective diffusivity, and on the anomalous scaling of structure functions of a passive scalar advected by a G…
Coarse-grained description of a passive scalar
Antonio Celani, Marco Martins Afonso, Andrea Mazzino
The issue of the parameterization of small-scale dynamics is addressed in the context of passive-scalar turbulence. The basic idea of our strategy is to identify dynamical equation…
