High-speed X-ray imaging of a ball impacting on loose sand
Tess Homan, Rob Mudde, Detlef Lohse +1
When a ball is dropped in fine, very loose sand, a splash and subsequently a jet are ob- served above the bed, followed by a granular eruption. To directly and quantitatively deter…
Geometric capture and escape of a microswimmer colliding with an obstacle
Saverio E. Spagnolie, Gregorio R. Moreno-Flores, Denis Bartolo +1
Motivated by recent experiments, we consider the hydrodynamic capture of a microswimmer near a stationary spherical obstacle. Simulations of model equations show that a swimmer app…
Direct Statistical Simulation of a Jet
J. B. Marston, Wanming Qi, S. M. Tobias
We review progress that has been made in utilizing one form of Direct Statistical Simulation (DSS) to describe geophysical and astrophysical flows that are anisotropic and inhomoge…
The role of fluctuations across a density interface
Antoine Venaille, Louis Gostiaux, Joël Sommeria
A statistical mechanics theory for a fluid stratified in density is presented. The predicted statistical equilibrium state is the most probable outcome of turbulent stirring. The s…
Finite-size effects in parametric subharmonic instability
Baptiste Bourget, Hélène Scolan, Thierry Dauxois +3
The parametric subharmonic instability in stratified fluids depends on the frequency and the amplitude of the primary plane wave. In this paper, we present experimental and numeric…
Ribbon Turbulence
Antoine Venaille, Louis-Philippe Nadeau, Geoffrey K. Vallis
We investigate the non-linear equilibration of a two-layer quasi-geostrophic flow in a channel forced by an imposed unstable zonal mean flow, paying particular attention to the rol…
Time-symmetry breaking in turbulence
Jennifer Jucha, Haitao Xu, Alain Pumir +1
In three-dimensional turbulent flows, the flux of energy from large to small scales breaks time symmetry. We show here that this irreversibility can be quantified by following the…
Chaotic mixing in effective compressible flows
Romain Volk, Cyril Mauger, Mickael Bourgoin +3
We study numerically joint mixing of salt and colloids by a chaotic velocity field , and how salt inhomogeneities accelerate or delay colloid mixing by inducing a veloc…
Collision rate for suspensions at large Stokes numbers - comparing Navier-Stokes and synthetic turbulence
Michel Voßkuhle, Alain Pumir, Emmanuel Lévêque +1
The use of simplified models of turbulent flows provides an appealing possibility to study the collision rate of turbulent suspensions, especially in conditions relevant to astroph…
Robust estimate of dynamo thresholds in the von Kármán sodium experiment using the Extreme Value Theory
Davide Faranda, Mickael Bourgoin, Sophie Miralles +5
We apply a new threshold detection method based on the extreme value theory to the von Kármán sodium (VKS) experiment data. The VKS experiment is a successful attempt to get a dyna…
Probing quantum and classical turbulence analogy through global bifurcations in a von Kármán liquid Helium experiment
B Saint-Michel, E Herbert, J Salort +15
We report measurements of the dissipation in the Superfluid Helium high REynold number von Karman flow (SHREK) experiment for different forcing conditions, through a regime of glob…
Long-term memory in experiments and numerical simulations of hydrodynamic and magnetohydrodynamic turbulence
Pablo Mininni, Pablo Dmitruk, Philippe Odier +5
We analyze time series stemming from experiments and direct numerical simulations of hydrodynamic and magnetohydrodynamic turbulence. Simulations are done in periodic boxes, but wi…
