Dynamical and statistical properties of large scales in turbulence
A. Alexakis, M. E. Brachet, S. Fauve +1
We present a review of results concerning the properties of scales larger than the forcing scale in turbulent flows. In three-dimensional turbulence, when the power driving the flo…
Rayleigh-B{é}nard Convection with Phase Change Close to the Critical Point
Valentin Mouet, Guillaume Michel, François Pétrélis +1
Rayleigh-B{é}nard convection is investigated with sulfur hexafluoride (SF) in the vicinity of its critical point. In the supercritical domain, direct measurements of the heat f…
Thermoelectricity at a gallium-mercury liquid metal interface
Marlone Vernet, Stephan Fauve, Christophe Gissinger
We present experimental evidence of a thermoelectric effect at the interface between two liquid metals. Using superimposed layers of mercury and gallium in a cylindrical vessel ope…
Intermittency as a consequence of a stationarity constraint on the energy flux
Sébastien Aumaître, Stéphan Fauve
In his seminal work on turbulence, Kolmogorov made use of the stationary hypothesis to determine the Power Density Spectrum of the velocity field in turbulent flows. However to our…
Experimental observation of spontaneous temperature fluctuations in turbulent flows
Gaurav Prabhudesai, Stephane Perrard, Francois Petrelis +1
Even in the absence of externally applied temperature gradients, spontaneously generated temperature fluctuations arise in turbulent flows. We experimentally study these fluctuatio…
Turbulence in electromagnetically-driven Keplerian flows
Marlone Vernet, Michael Pereira, Stephan Fauve +1
The flow of an electrically conducting fluid in a thin disc under the action of an azimuthal Lorentz force is studied experimentally. At small forcing, the Lorentz force is balance…
Capillary wave turbulence experiments in microgravity
Michael Berhanu, Eric Falcon, Guillaume Michel +2
Using the FLUIDICS (Fluid Dynamics in Space) experiment in the International Space Station, turbulence of capillary waves at the air-water interface is experimentally investigated…
Bifurcations of a large scale circulation in a quasi-bidimensional turbulent flow
Guillaume Michel, Johann Herault, François Pétrélis +1
We report the experimental study of the bifurcations of a large-scale circulation that is formed over a turbulent flow generated by a spatially periodic forcing. After shortly desc…
Decay rates of magnetic modes below the threshold of a turbulent dynamo
Johann Herault, François Pétrélis, Stephan Fauve
We measure the decay rates of magnetic field modes in a turbulent flow of liquid sodium below the dynamo threshold.We observe that turbulent fluctuations induce energy transfers be…
A quasi-elastic regime for vibrated granular gases
Sébastien Aumaître, Angel Alastuey, Stephan Fauve
Using simple scaling arguments and two-dimensional numerical simulations of a granular gas excited by vibrating one of the container boundaries, we study a double limit of small $1…
