Induction in a von Karman flow driven by ferromagnetic impellers

Gautier Verhille, Nicolas Plihon, Mickael Bourgoin +2

We study magnetohydrodynamics in a von Kármán flow driven by the rotation of impellers made of material with varying electrical conductivity and magnetic permeability. Gallium is t…

Statistical mechanics of two-dimensional Euler flows and minimum enstrophy states

A. Naso, P. H. Chavanis, B. Dubrulle

A simplified thermodynamic approach of the incompressible 2D Euler equation is considered based on the conservation of energy, circulation and microscopic enstrophy. Statistical eq…

Relaxation equations for two-dimensional turbulent flows with a prior vorticity distribution

P. H. Chavanis, A. Naso, B. Dubrulle

Using a Maximum Entropy Production Principle (MEPP), we derive a new type of relaxation equations for two-dimensional turbulent flows in the case where a prior vorticity distributi…

The effect of finite container size on granular jet formation

Stefan von Kann, Sylvain Joubaud, Gabriel A. Caballero-Robledo +2

When an object is dropped into a bed of fine, loosely packed sand, a surprisingly energetic jet shoots out of the bed. In this work we study the effect that boundaries have on the…

Large scale fluctuations and dynamics of the Bullard - von Kármán dynamo

Gautier Verhille, Nicolas Plihon, Grégory Fanjat +3

A synthetic fluid dynamo built in the spirit of the Bullard device [E. C. Bullard, Proc. Camb. Phil. Soc., 51, 744 (1955)] is investigated. It is a two-step dynamo in which one pro…

A Stochastic Representation of the Local Structure of Turbulence

Laurent Chevillard, Raoul Robert, Vincent Vargas

Based on the mechanics of the Euler equation at short time, we show that a Recent Fluid Deformation (RFD) closure for the vorticity field, neglecting the early stage of advection o…

Mixing in stratified gravity currents: Prandtl mixing length

Philippe Odier, Jun Chen, Michael K. Rivera +1

Shear-induced vertical mixing in a stratified flow is a key ingredient of thermohaline circulation. We experimentally determine the vertical flux of momentum and density of a force…
