A simple mechanism for the reversals of Earth's magnetic field
F. Petrelis, S. Fauve, E. Dormy +1
We show that a model, recently used to describe all the dynamical regimes of the magnetic field generated by the dynamo effect in the VKS experiment [1], also provides a simple exp…
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…
