Dynamical and statistical properties of large scales in turbulence
A. Alexakis, M. E. Brachet, S. Fauve +1
We present a review of results concerning the properties of scales larger than the forcing scale in turbulent flows. In three-dimensional turbulence, when the power driving the flo…
Magnetic reversals in a geodynamo model with a stably-stratified layer
Nicolás Pablo Müller, Christophe Gissinger, François Pétrélis
We study the process of magnetic reversals in the presence of a stably-stratified layer below the core-mantle boundary using direct numerical simulations of the incompressible magn…
Earthquake magnitude distribution and aftershocks: a statistical geometry explanation
François Pétrélis, Kristel Chanard, Alexandre Schubnel +1
The emergence of a power-law distribution for the energy released during an earthquake is investigated in several models. Generic features are identified which are based on the sel…
Statistics of phase fluctuations of an acoustic wave propagating through a turbulent flow
Gaurav Prabhudesai, Stephane Perrard, Francois Petrelis +1
We investigate the statistics of phase fluctuations of an acoustic wave propagating through a turbulent flow in line of sight (LOS) configuration. Experiments are performed on a cl…
1/f noise and anomalous scaling in Lévy noise-driven on-off intermittency
Adrian van Kan, François Pétrélis
On-off intermittency occurs in nonequilibrium physical systems close to bifurcation points and is characterised by an aperiodic switching between a large-amplitude "on" state and a…
Enhanced dynamo growth in nonhomogeneous conducting fluids
Florence Marcotte, Basile Gallet, Francois Pétrélis +1
We address magnetic-field generation by dynamo action in systems with inhomogeneous electrical conductivity and magnetic permeability. More specifically, we first show that the Tay…
