Different transport regimes in a spatially-extended recirculating background
P. Castiglione, R. Festa, A. Mazzino
Passive scalar transport in a spatially-extended background of roll convection is considered in the time-periodic regime. The latter arises due to the even oscillatory instability…
Interference phenomena in scalar transport induced by a noise finite correlation time
A. Mazzino, P. Castiglione
The role played on the scalar transport by a finite, not small, correlation time, , for the noise velocity is investigated, both analytically and numerically. For small '…
Transport in finite size systems: an exit time approach
P. Castiglione, M. Cencini, A. Vulpiani +1
In the framework of chaotic scattering we analyze passive tracer transport in finite systems. In particular, we study models with open streamlines and a finite number of recirculat…
Dispersion of passive tracers in velocity field with non delta-correlated noise
P. Castiglione, A. Crisanti
The diffusive properties in velocity fields whose small scales are parameterized by non -correlated noise is investigated using multiscale technique. The analytical expression o…
