Reduction of velocity fluctuations in a turbulent flow of gallium by an external magnetic field
Michael Berhanu, Basile Gallet, Nicolas Mordant +1
The magnetic field of planets or stars is generated by the motion of a conducting fluid through a dynamo instability. The saturation of the magnetic field occurs through the reacti…
Bypassing Cowling's theorem in axisymmetric fluid dynamos
Christophe Gissinger, Emmanuel Dormy, Stephan Fauve
We present a numerical study of the magnetic field generated by an axisymmetrically forced flow in a spherical domain. At small enough Reynolds number, Re, the flow is axisymmetric…
Effect of magnetic boundary conditions on the dynamo threshold of von Karman swirling flows
Christophe Gissinger, Alexei Iskakov, Stephan Fauve +1
We study the effect of different boundary conditions on the kinematic dynamo threshold of von Karman type swirling flows in a cylindrical geometry. Using an analytical test flow, w…
Fluctuations of energy flux in wave turbulence
Eric Falcon, Sebastien Aumaitre, Claudio Falcon +2
We report that the power driving gravity and capillary wave turbulence in a statistically stationary regime displays fluctuations much stronger than its mean value. We show that it…
On the magnetic fields generated by experimental dynamos
F. Petrelis, N. Mordant, S. Fauve
We review the results obtained by three successful fluid dynamo experiments and discuss what has been learnt from them about the effect of turbulence on the dynamo threshold and sa…
Magnetic induction in a turbulent flow of liquid sodium: mean behaviour and slow fluctuations
F. Ravelet, R. Volk, A. Chiffaudel +10
We study the flow response to an externally imposed homogeneous magnetic field in a turbulent swirling flow of liquid sodium -- the VKS2 experiment in which magnetic Reynolds numbe…
