We report the observation of dynamo action in the von Kármán sodium experiment, ie, the
generation of a magnetic field by a strongly turbulent swirling flow of liquid sodium. Both …

Magnetic field generation and evolution in celestial bodies—the subject matter of the theory
of the dynamo—held Ya B Zeldovich's interest for years. Over the time since then, the study …

Recent decades have seen enormous progress in the experimental investigation of
fundamental processes that are relevant to geophysical and astrophysical fluid dynamics …

The von Kármán Sodium (VKS) experiment studies dynamo action in the flow generated
inside a cylinder filled with liquid sodium by the rotation of coaxial impellers (the von Kármán …

The effect of the nutation angle on the flow inside a precessing cylinder is experimentally
explored and compared with numerical simulations. The focus is laid on the typical …

It is widely known that cosmic magnetic fields, ie the fields of planets, stars, and galaxies, are
produced by the hydromagnetic dynamo effect in moving electrically conducting fluids. It is …

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 …

We study the effect of different boundary conditions on the kinematic dynamo threshold of
von Kármán type swirling flows in a cylindrical geometry. Using an analytical test flow, we …

A crucial point for the understanding of the von Kármán–sodium (VKS) dynamo experiment
is the influence of soft-iron impellers. We present numerical simulations of a VKS-like …

Numerical simulations of the kinematic induction equation are performed on a model
configuration of the Cadarache von-Kármán-sodium dynamo experiment. The effect of a …
