Thermodynamic limits to information harvesting by sensory systems
Stefano Bo, Marco Del Giudice, Antonio Celani
In view of the relation between information and thermodynamics we investigate how much information about an external protocol can be stored in the memory of a stochastic measuremen…
Point-source scalar turbulence
Antonio Celani, Marco Martins Afonso, Andrea Mazzino
The statistics of a passive scalar randomly emitted from a point source is investigated analytically. Our attention has been focused on the two-point equal-time scalar correlation…
Shear effects on passive scalar spectra
A. Celani, M. Cencini, M. Vergassola +2
The effects of a large-scale shear on the energy spectrum of a passively advected scalar field are investigated. The shear is superimposed on a turbulent isotropic flow, yielding a…
Large-Eddy Simulation closures of passive scalar turbulence: a systematic approach
M. Martins Afonso, A. Celani, R. Festa +1
The issue of the parameterization of small scale (``subgrid'') turbulence is addressed in the context of passive scalar transport. We focus on the Kraichnan advection model which l…
