### Kolmogorovian active turbulence of a sparse assembly of interacting Marangoni surfers

Mickaël Bourgoin, Ronan Kervil, Cécile Cottin-Bizonne, Florence Raynal, Romain Volk & Christophe Ybert

Active matter, composed of self-propelled entities, forms a wide class of out-of-equilibrium systems that display striking collective behaviors, among which, the so-called active turbulence where (...)

### Transition from non-swirling to swirling axisymmetric turbulence

Zecong Qin, Hugues Faller, Bérengère Dubrulle, Aurore Naso & Wouter Bos

Strictly axisymmetric turbulence, i.e., turbulence governed by the Navier-Stokes equations modified such that the flow is invariant in the azimuthal direction, is a system intermediate between (...)

### Single-particle Lagrangian statistics from direct numerical simulations of rotating-stratified turbulence

Dhawal Buaria, Alain Pumir, Fabio Feraco, Raffaele Marino, Annick Pouquet, Duane Rosenberg & Leonardo Primavera

Geophysical fluid flows are predominantly turbulent and often strongly affected by the Earth’s rotation, as well as by stable density stratification. Using direct numerical simulations of forced (...)

### Numerical study of extreme mechanical force exerted by a turbulent flow on a bluff body by direct and rare-event sampling techniques

Thibault Lestang, Freddy Bouchet & Emmanuel Lévêque

This study investigates, by means of numerical simulations, extreme mechanical force exerted by a turbulent flow impinging on a bluff body, and examines the relevance of two distinct rare-event (...)

### Partitioning Waves and Eddies in Stably Stratified Turbulence

Henri Lam, Alexandre Delache & Fabien Godeferd

We consider the separation of motion related to internal gravity waves and eddy dynamics in stably stratified flows obtained by direct numerical simulations. The waves’ dispersion relation links (...)

### Analysis of turbulence characteristics in a temporal dense gas compressible mixing layer using direct numerical simulation

Aurélien Vadrot, Alexis Giauque & Christophe Corre

This study investigates the effects of a Bethe–Zel’dovich–Thompson (BZT) dense gas (FC-70) on the development of a turbulent compressible mixing layer at a convective Mach number $M_c=1.1$. (...)

### Staircase scaling of short-time energy transfer in turbulence

Le Fang, T. Wu & Wouter Bos

It is illustrated that a sharply truncated initial kinetic energy spectrum evolves to a staircase-shaped spectrum at short times. This effect is directly associated with the triadic nature of the (...)

### Efficiency of laminar and turbulent mixing in wall-bounded flows

Benjamin Kadoch, Wouter Bos & Kai Schneider

A turbulent flow mixes in general more rapidly a passive scalar than a laminar flow does. From an energetic point of view, for statistically homogeneous or periodic flows, the laminar regime is (...)

### Scaling laws in axisymmetric magnetohydrodynamic duct flows

Alexandre Poyé, Olivier Agullo, Nicolas Plihon, Wouter Bos, Victor Desangles & Guillaume Bousselin

We report on a numerical study of axisymmetric flow of liquid metal in a circular duct with a rectangular cross section. The flow is forced through the combination of an axial magnetic field and (...)

### Direct numerical simulations of forced homogeneous isotropic turbulence in a dense gas

Alexis Giauque, Christophe Corre & Aurélien Vadrot

Direct Numerical Simulations (DNS) of forced homogeneous isotropic turbulence in a dense gas (FC-70), accurately described by a complex EoS, are computed for a turbulent Mach number of 0.8. In a (...)

### Nonlinear Effects on the Precessional Instability in Magnetized Turbulence

Abdelaziz Salhi, Amor Khlifi & Claude Cambon

By means of direct numerical simulations (DNS), we study the impact of an imposed uniform magnetic field on precessing magnetohydrodynamic homogeneous turbulence with a unit magnetic Prandtl (...)

### Importance of fluid inertia for the orientation of spheroids settling in turbulent flow

Muhammad Zubair Sheikh, Kristian Gustavsson, Diego Lopez, Emmanuel Lévêque, Bernhard Mehlig, Alain Pumir & Aurore Naso

How non-spherical particles orient as they settle in a flow has important practical implications in a number of scientific and engineering problems. In a quiescent fluid, a slowly settling (...)

### Sudden diffusion of turbulent mixing layers in weakly coupled plasmas under compression

Giovanni Viciconte, Benoît-Joseph Gréa, Fabien S. Godeferd, Philippe Arnault & Jean Clérouin

The rapid growth of viscosity driven by temperature increase in turbulent plasmas under compression induces a sudden dissipation of kinetic energy, eventually leading to the relaminarization of (...)

### The turbulent Faraday instability in miscible fluids

Antoine Briard, Louis Gostiaux & Benoît-Joseph Gréa

Experiments of a turbulent mixing zone created by the Faraday instability at the statically stable interface between salt and fresh water are presented. The two-layer system, contained in a (...)
