Depletion of nonlinearity in two-dimensional turbulence
Andrey Pushkarev, Wouter Bos
The strength of the nonlinearity is measured in decaying two-dimensional turbulence, by comparing its value to that found in a Gaussian field. It is shown how the nonlinearity drop…
Influence of fine particles on the stability of a humid granular pile
Xixi Huang, Sandrine Bec, J. Colombani
We have investigated by rotating drum experiments the influence of a small amount of fine particles on the stability of a granular heap. The fine particles are shown to have a stro…
The distribution of "time of flight" in three dimensional stationary chaotic advection
Florence Raynal, Philippe Carrière
The distributions of "time of flight" (time spent by a single fluid particle between two crossings of the Poincaré section) are investigated for five different 3D stationary chaoti…
Propagation Length of Self-healing Slip Pulses at the Onset of Sliding: A Toy Model
Oleg Braun, J Scheibert
Macroscopic sliding between two solids is triggered by the propagation of a micro-slip front along the frictional interface. In certain conditions, sliding is preceded by the propa…
Flow dynamics and magnetic induction in the von-Karman plasma experiment
Nicolas Plihon, Guillaume Bousselin, Francesco Palermo +7
The von-Karman plasma experiment is a novel versatile experimental device designed to explore the dynamics of basic magnetic induction processes and the dynamics of flows driven in…
Introduction of longitudinal and transverse Lagrangian velocity increments in homogeneous and isotropic turbulence
Emmanuel Leveque, Aurore Naso
Based on geometric considerations, longitudinal and transverse Lagrangian velocity increments are introduced as components along, and perpendicular to, the displacement of fluid pa…
