Magnetic Taylor-Proudman constraint explains the flows into the Tangent Cylinder
Alban Pothérat, Kélig Aujogue, François Debray
Tangent Cylinders (TCs) have shaped our understanding of planetary dynamos and liquid cores. The Taylor-Proudman Constraint (TPC) due to planetary rotation creates these imaginary…
PIV mapping of pressure and velocity fields in the plane magnetohydrodynamic Couette flow
Brahim Moudjed, Alban Pothérat, Martin Holdsworth
We present the first simultaneous mapping of two-dimensional, time-dependent velocity and pressure fields in a plane Couette flow pervaded by a transverse magnetic field. While ele…
Inverse and direct energy cascades in 3D MHD turbulence at low-Rm
N. T. Baker, A. Pothérat, L. Davoust +1
This experimental study analyzes the relationship between the dimensionality of turbulence and the upscale or downscale nature of its energy transfers. We do so by forcing low-…
Experimental study of the convection in a rotating tangent cylinder
Kélig Aujogue, Alban Pothérat, Binod Sreenivasan +1
This paper experimentally investigates the convection in a fast rotating Tangent Cylinder (TC), for Ekman numbers down to , in a configuration relevant to the…
Controlling the dimensionality of low-Rm MHD turbulence experimentally
Nathaniel T. Baker, Alban Pothérat, Laurent Davoust +2
This paper introduces an experimental apparatus, which drives turbulence electrically in a liquid metal pervaded by a high magnetic field. Unlike past magnetohydrodynamic (MHD) set…
Do magnetic fields enhance turbulence at low magnetic Reynolds number ?
Alban Pothérat, Rico Klein
Imposing a magnetic field on a turbulent flow of electrically conducting fluid incurs the Joule effect. A current paradigm is that the corresponding dissipation increases with the…
Dimensionality, secondary flows and helicity in low-Rm MHD vortices
Nathaniel T. Baker, Alban Pothérat, Laurent Davoust
In this paper, we examine the dimensionality of a single electrically driven vortex bounded by two no-slip and perfectly insulating horizontal walls distant by . The study was p…
Direct and inverse pumping in flows with homogeneous and non-homogeneous swirl
A. Pothérat, F. Rubiconi, Y. Charles +1
The conditions in which meridional recirculations appear in swirling flows above a fixed wall are analysed. In the classical Bodewädt problem, where the swirl tends towards an aysm…
Experimental evidence of Alfvén wave propagation in a Gallium alloy
Thierry Alboussiere, Philippe Cardin, François Debray +5
Experiments with a liquid metal alloy, galinstan, are reported and show clear evidence of Alfvén wave propagation as well as resonance of Alfvén modes. Galinstan is liquid at room…
