The glass transition in a nutshell: a source of inspiration to describe the subcritical transition to turbulence
Olivier Dauchot, Eric Bertin
The starting point of the present work is the observation of possible analogies, both at the phenomenological and at the methodological level, between the subcritical transition to…
Multiple collisions in turbulent flows
Michel Voßkuhle, Emmanuel Lévêque, Michael Wilkinson +1
In turbulent suspensions, collision rates determine how rapidly particles coalesce or react with each other. To determine the collision rate, many numerical studies rely on the 'Gh…
Large spheres motion in a non homogeneous turbulent flow
Nathanael Machicoane, Robert Zimmermann, Lionel Fiabane +3
We investigate the dynamics of very large particles freely advected in a turbulent von Karman flow. Contrary to other experiments for which the particle dynamics is generally studi…
Melting dynamics of large ice balls in a turbulent swirling flow
N. Machicoane, J. Bonaventure, R. Volk
We study the melting dynamics of large ice balls in a turbulent von Karman flow at very high Reynolds number. Using an optical shadowgraphy setup, we record the time evolution of p…
Prevalence of the sling effect for enhancing collision rates in turbulent suspensions
Michel Voßkuhle, Alain Pumir, Emmanuel Lévêque +1
Turbulence facilitates collisions between particles suspended in a turbulent flow. Two effects have been proposed which can enhance the collision rate at high turbulence intensitie…
Sign cancellation and scaling in the vertical component of velocity and vorticity in rotating turbulence
E. Horne, P. D. Mininni
We study sign changes and scaling laws in the Cartesian components of the velocity and vorticity of rotating turbulence, in the helicity, and in the components of vertically-averag…
Orientation dynamics of small, triaxial-ellipsoidal particles in isotropic turbulence
Laurent Chevillard, Charles Meneveau
The orientation dynamics of small anisotropic tracer particles in turbulent flows is studied using direct numerical simulation (DNS) and results are compared with Lagrangian stocha…
Kinetic theory of jet dynamics in the stochastic barotropic and 2D Navier-Stokes equations
Freddy Bouchet, Cesare Nardini, Tomás Tangarife
We discuss the dynamics of zonal (or unidirectional) jets for barotropic flows forced by Gaussian stochastic fields with white in time correlation functions. This problem contains…
Experimental study of parametric subharmonic instability for internal waves
Baptiste Bourget, Thierry Dauxois, Sylvain Joubaud +1
Internal waves are believed to be of primary importance as they affect ocean mixing and energy transport. Several processes can lead to the breaking of internal waves and they usua…
