Rotational intermittency and turbulence induced lift experienced by large particles in a turbulent flow
Robert Zimmermann, Yoann Gasteuil, Mickael Bourgoin +3
The motion of a large, neutrally buoyant, particle, freely advected by a turbulent flow is determined experimentally. We demonstrate that both the translational and angular acceler…
Longitudinal and Transverse structure functions in high Reynolds-number turbulence
Rainer Grauer, Holger Homann, Jean-Francois Pinton
Using exact relations between velocity structure functions (Hill, Hill and Boratav, and Yakhot) and neglecting pressure contributions in a first approximation, we obtain a closed s…
Two-Point Vorticity Statistics in the Inverse Turbulent Cascade
R. Friedrich, M. Voßkuhle, O. Kamps +1
We present a statistical analysis of the two-point vorticity probability density of the vorticity field generated in the inverse cascade of stationary two-dimensional turbulence.
Solvable phase diagrams and ensemble inequivalence for two-dimensional and geophysical turbulent flows
Antoine Venaille, Freddy Bouchet
Using explicit analytical computations, generic occurrence of inequivalence between two or more statistical ensembles is obtained for a large class of equilibrium states of two-dim…
Tracking the dynamics of translation and absolute orientation of a sphere in a turbulent flow
Robert Zimmermann, Yoann Gasteuil, Mickael Bourgoin +3
We study the 6-dimensional dynamics -- position and orientation -- of a large sphere advected by a turbulent flow. The movement of the sphere is recorded with 2 high-speed cameras.…
Impact of trailing wake drag on the statistical properties and dynamics of finite-sized particle in turbulence
Enrico Calzavarini, Romain Volk, Emmanuel Leveque +2
We study by means of an Eulerian-Lagrangian model the statistical properties of velocity and acceleration of a neutrally-buoyant finite-sized particle in a turbulent flow statistic…
Statistical mechanics of Fofonoff flows in an oceanic basin
A. Naso, P. H. Chavanis, B. Dubrulle
We study the minimization of potential enstrophy at fixed circulation and energy in an oceanic basin with arbitrary topography. For illustration, we consider a rectangular basin an…
On the origin of intermittency in wave turbulence
Eric Falcon, S. G. Roux, Claude Laroche
Using standard signal processing tools, we experimentally report that intermittency of wave turbulence on the surface of a fluid occurs even when two typical large-scale coherent s…
Statistical mechanics of Beltrami flows in axisymmetric geometry: Equilibria and bifurcations
Aurore Naso, Simon Thalabard, Gilles Collette +2
We characterize the thermodynamical equilibrium states of axisymmetric Euler-Beltrami flows. They have the form of coherent structures presenting one or several cells. We find the…
Dynamics of inertial particles in a turbulent von Karman flow
Romain Volk, Enrico Calzavarini, Emmanuel Leveque +1
We study the dynamics of neutrally buoyant particles with diameters varying in the range [1, 45] in Kolmogorov scale units (eta) and Reynolds numbers based on Taylor scale between…
