Subcritical turbulent transition in rotating and curved shear flows
P-Y. Longaretti, O. Dauchot
The effects of global flow rotation and curvature on the subcritical transition to turbulence in shear flows are examined. The relevant time-scales of the problem are identified by…
Free volume distributions inside a bidimensional granular medium
F. da Cruz, F. Lechenault, O. Dauchot +1
We investigate experimentally within a two-dimensional cell the distribution of the free volume associated either to single grains or to clusters of grains. Our main result is that…
Non-equilibrium temperatures in steady-state systems with conserved energy
Eric Bertin, Olivier Dauchot, Michel Droz
We study a class of non-equilibrium lattice models describing local redistributions of a globally conserved quantity, which is interpreted as an energy. A particular subclass can b…
Temperature in nonequilibrium systems with conserved energy
Eric Bertin, Olivier Dauchot, Michel Droz
We study a class of nonequilibrium lattice models which describe local redistributions of a globally conserved energy. A particular subclass can be solved analytically, allowing to…
A powerful local shear instability in stratified disks
D. Richard, F. Hersant, O. Dauchot +3
In this paper, we show that astrophysical accretion disks are dynamically unstable to non-axisymmetric disturbances. This instability is present in any stably stratified anticyclon…
