Kinematic dynamo action of a precession driven flow based on the results of water experiments and hydrodynamic simulations
Andre Giesecke, Tobias Vogt, Thomas Gundrum +1
The project DRESDYN (DREsden Sodium facility for DYNamo and thermohydraulic studies) conducted at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) provides a new platform for a variety…
Instability of precession driven Kelvin modes: Evidence of a detuning effect
Johann Herault, Andre Giesecke, Thomas Gundrum +1
We report an experimental study of the instability of a nearly-resonant Kelvin mode forced by precession in a cylindrical vessel. The instability is detected above a critical prece…
On the synchronizability of Tayler-Spruit and Babcock-Leighton type dynamos
Frank Stefani, André Giesecke, Norbert Weber +1
The solar cycle appears to be remarkably synchronized with the gravitational torques exerted by the tidally dominant planets Venus, Earth and Jupiter. Recently, a possible synchron…
Sloshing instability and electrolyte layer rupture in liquid metal batteries
Norbert Weber, Pascal Beckstein, Wietze Herreman +4
Liquid metal batteries (LMBs) are discussed today as a cheap grid scale energy storage, as required for the deployment of fluctuating renewable energies. Built as a stable density…
Transitions in a magnetized quasi-laminar spherical Couette Flow
C. Kasprzyk, E. Kaplan, M. Seilmayer +1
First results of a new spherical Couette experiment are presented. The liquid metal flow in a spherical shell is exposed to a homogeneous axial magnetic field. For a Reynolds numbe…
Synchronized helicity oscillations: a link between planetary tides and the solar cycle?
F. Stefani, A. Giesecke, N. Weber +1
Recent years have seen an increased interest in the question of whether the gravitational action of planets could have an influence on the solar dynamo. Without discussing the obse…
