Effects of turbulence, resistivity and boundary conditions on helicoidal flow collimation: consequences for the Von-Kármán-Sodium dynamo experiment
J. Varela, S. Brun, B. Dubrulle +1
We present hydrodynamic and magneto-hydrodynamic simulations of a liquid sodium flow using the compressible MHD code PLUTO to investigate the magnetic field regeneration in the Von…
The role of boundary conditions on helicoidal flow collimation: consequences for the Von-Kármán-Sodium dynamo experiment
J. Varela, S. Brun, B. Dubrulle +1
We present hydrodynamic and magneto-hydrodynamic simulations of liquid sodium flow with the PLUTO compressible MHD code to investigate influence of magnetic boundary conditions on…
Metal pad roll instability in liquid metal batteries
Norbert Weber, Pascal Beckstein, Vladimir Galindo +4
The increasing deployment of renewable energies requires three fundamental changes to the electric grid: more transmission lines, a flexibilisation of the demand and grid scale ene…
Experimental realization of dynamo action: present status and prospects
Andre Giesecke, Frank Stefani, Thomas Gundrum +3
In the last decades, the experimental study of dynamo action has made great progress. However, after the dynamo experiments in Karlsruhe and Riga, the von-Karman-Sodium (VKS) dynam…
Remarks on the stability of the Navier-Stokes equations supplemented with stress-free boundary conditions
J. -L. Guermond, J. Léorat, F. Luddens +1
The purpose of this note is to analyze the long term stability of the Navier-Stokes equations supplemented with the Coriolis force and the stress-free boundary condition. It is sho…
Influence of high permeability disks in an axisymmetric model of the Cadarache dynamo experiment
A. Giesecke, C. Nore, F. Stefani +5
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 localized axi…
Nonlinear dynamo action in a precessing cylindrical container
C. Nore, J. Léorat, J. -L. Guermond +1
It is numerically demonstrated by means of a magnetohydrodynamics (MHD) code that precession can trigger the dynamo effect in a cylindrical container. This result adds credit to th…
Electromagnetic induction in non-uniform domains
A. Giesecke, C. Nore, F. Luddens +4
Kinematic simulations of the induction equation are carried out for different setups suitable for the von-Kármán-Sodium (VKS) dynamo experiment. Material properties of the flow dri…
Impact of impellers on the axisymmetric magnetic mode in the VKS2 dynamo experiment
R. Laguerre, C. Nore, A. Ribeiro +3
In the VKS2 (von Kármán Sodium 2) successful dynamo experiment of September 2006, the magnetic field that was observed showed a strong axisymmetric component, implying that non axi…
Boundary layers and emitted excitations in nonlinear Schrodinger superflow past a disk
Chi-Tuong Pham, Caroline Nore, Marc-Etienne Brachet
The stability and dynamics of nonlinear Schrodinger superflows past a two-dimensional disk are investigated using a specially adapted pseudo-spectral method based on mapped Chebych…
A Hamiltonian weak-wave model for shallow-water flow
Caroline Nore, Theodore G. Shepherd
A reduced dynamical model is derived which describes the interaction of weak inertia-gravity waves with nonlinear vortical motion in the context of rotating shallow-water flow. The…
