Experimental evidence of a triadic resonance of plane inertial waves in a rotating fluid

Guilhem Bordes, Frédéric Moisy, Thierry Dauxois +1

Plane inertial waves are generated using a wavemaker, made of oscillating stacked plates, in a rotating water tank. Using particle image velocimetry, we observe that, after a trans…

A phenomenological theory of Eulerian and Lagrangian velocity fluctuations in turbulent flows

Laurent Chevillard, Bernard Castaing, Alain Arneodo +3

A phenomenological theory of the fluctuations of velocity occurring in a fully developed homogeneous and isotropic turbulent flow is presented. The focus is made on the fluctuation…

Statistical properties of supersonic turbulence in the Lagrangian and Eulerian frameworks

Lukas Konstandin, Christoph Federrath, Ralf S. Klessen +1

We present a systematic study of the influence of different forcing types on the statistical properties of supersonic, isothermal turbulence in both the Lagrangian and Eulerian fra…

Lagrangian time correlations of vorticity alignments in isotropic turbulence: observations and model predictions

Laurent Chevillard, Charles Meneveau

Motivated by results from recent particle tracking experiments in turbulence (Xu et al., Nat. Phys. 7, 709 (2011)), we study the Lagrangian time correlations of vorticity alignment…

Mach Number Dependence of Turbulent Magnetic Field Amplification: Solenoidal versus Compressive Flows

Christoph Federrath, Gilles Chabrier, Jennifer Schober +3

We study the growth rate and saturation level of the turbulent dynamo in magnetohydrodynamical simulations of turbulence, driven with solenoidal (divergence-free) or compressive (c…

Degassing cascades in a shear-thinning viscoelastic fluid

Valérie Vidal, François Soubiran, Thibaut Divoux +1

We report the experimental study of the degassing dynamics through a thin layer of shear-thinning viscoelastic fluid (CTAB/NaSal solution), when a constant air flow is imposed at i…

Experimental evidence of Alfvén wave propagation in a Gallium alloy

Thierry Alboussiere, Philippe Cardin, François Debray +5

Experiments with a liquid metal alloy, galinstan, are reported and show clear evidence of Alfvén wave propagation as well as resonance of Alfvén modes. Galinstan is liquid at room…

Local and nonlocal pressure Hessian effects in real and synthetic fluid turbulence

Laurent Chevillard, Emmanuel Leveque, Francesco Taddia +3

The Lagrangian dynamics of the velocity gradient tensor A in isotropic and homogeneous turbulence depend on the joint action of the self-streching term and the pressure Hessian. Ex…

Spherical Ornstein-Uhlenbeck processes

Michael Wilkinson, Alain Pumir

The paper considers random motion of a point on the surface of a sphere, in the case where the angular velocity is determined by an Ornstein-Uhlenbeck process. The solution is full…

Resurrecting Dead-water Phenomenon

Matthieu Mercier, Romain Vasseur, Thierry Dauxois

We revisit experimental studies performed by Ekman on dead-water using modern techniques in order to present new insights on this peculiar phenomenon. We extend its description to…

Reynolds number effect on the velocity increment skewness in isotropic turbulence

Wouter J. T. Bos, Laurent Chevillard, Julian F. Scott +1

Second and third order longitudinal structure functions and wavenumber spectra of isotropic turbulence are computed using the EDQNM model and compared to results of the multifracta…
