We briefly review helicity dynamics, inverse and bidirectional cascades in fluid and
magnetohydrodynamic (MHD) turbulence, with an emphasis on the latter. The energy of a …

We report the results of an extensive numerical study of the small-scale turbulent dynamo.
The primary focus is on the case of large magnetic Prandtl numbers Pr m, which is relevant …

We report the first experimental observation of reversals of a dynamo field generated in a
laboratory experiment based on a turbulent flow of liquid sodium. The magnetic field …

This paper is a detailed report on a programme of direct numerical simulations of
incompressible nonhelical randomly forced magnetohydrodynamic (MHD) turbulence that …

We analyze the initial, kinematic stage of magnetic field evolution in an isotropic and
homogeneous turbulent conducting fluid with a rough velocity field, v (l)∼ l α, α< 1. This …

We present a three-pronged numerical approach to the dynamo problem at low magnetic
Prandtl numbers PM. The difficulty of resolving a large range of scales is circumvented by …

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 …

We study numerically the dependence of the critical magnetic Reynolds number Rm c for the
turbulent small-scale dynamo on the hydrodynamic Reynolds number Re. The turbulence is …

We study the magnetic induction in a confined swirling flow of liquid sodium, at integral
magnetic Reynolds numbers up to 50. More precisely, we measure in situ the magnetic field …

We study the inverse cascade of magnetic helicity in conducting fluids, as pertinent to the
generation and dynamics of magnetic fields as observed, eg, in the solar corona, by …
