Rescaling invariance and anomalous energy transport in a small vertical column of grains
Andrea Gnoli, Giorgio Pontuale, Andrea Puglisi +1
It is well known that energy dissipation and finite size can deeply affect the dynamics of granular matter, often making usual hydrodynamic approaches problematic. Here we report o…
Breakdown of Scaling and Friction Weakening in the Critical Granular Flow
Andrea Baldassarri, Mario A. Annunziata, Andrea Gnoli +2
The way granular materials response to an applied shear stress is of the utmost relevance to both human activities and natural environment. One of the their most intriguing and les…
Inherent thermal convection in a gas inside a box under a gravity field
F. Vega Reyes, A. Puglisi, G. Pontuale +1
We theoretically prove the existence in granular fluids of a thermal convection that is inherent, in the sense that is always present and has no thermal gradient threshold (convect…
Dissipative lateral walls are sufficient to trigger convection in vibrated granular gases
G. Pontuale, Andrea Gnoli, Francisco Vega Reyes +1
Buoyancy-driven (thermal) convection in dilute granular media, fluidized by a vibrating base, is known to appear without the need of lateral boundaries in a restricted region of pa…
Thermal convection in granular gases with dissipative lateral walls
Giorgio Pontuale, Andrea Gnoli, Francisco Vega Reyes +1
We consider a granular gas under the action of gravity, fluidized by a vibrating base. We show that a horizontal temperature gradient, here induced by limiting dissipative lateral…
How log-normal is your country? An analysis of the statistical distribution of the exported volumes of products
Mario Alberto Annunziata, Alberto Petri, Giorgio Pontuale +1
We have considered the statistical distributions of the volumes of the different products exported by 148 countries. We have found that the form of these distributions is not uniqu…
