Ohmic and viscous damping of inner core translational oscillations
Paolo Personnettaz, David Cébron, Nathanaël Schaeffer +2
Large earthquakes can trigger translational oscillations of Earth's inner core (Slichter modes), yet their damping remains uncertain. Using simulations, we quantify viscous and Ohm…
Magnetohydrodynamic drag on an oscillating sphere in a rotating spherical cavity
David Cébron, Paolo Personnettaz
Oscillating-sphere drag is a classical fluid-mechanics problem, yet no theory simultaneously accounts for confinement, rotation, viscosity and magnetic fields. We consider a conduc…
The effect of split endcaps on the flow dynamics in a tall Taylor-Couette setup
A. Mishra, P. Personnettaz, G. Mamatsashvili +2
The effects of axial boundaries, or endcaps are of fundamental interest in many Taylor-Couette (TC) flow experiments. A main challenge in those experiments has been to minimize the…
Yamdb: easily accessible thermophysical properties of liquid metals and molten salts
Tom Weier, William Nash, Paolo Personnettaz +1
Yamdb (Yet another materials data base) addresses the need to provide thermophysical properties of liquid metals and molten salts in an easily accessible manner. Mathematical relat…
Layer coupling between solutal and thermal convection in liquid metal batteries
Paolo Personnettaz, Tanja Sophia Klopper, Norbert Weber +1
For longer than one decade, liquid metal batteries (LMBs) are developed with the primary aim to provide economic stationary energy storage. Featuring two liquid metal electrodes se…
Cell voltage model for Li-Bi liquid metal batteries
Norbert Weber, Carolina Duczek, Gerrit M. Horstmann +5
Lithium-bismuth bimetallic cells are amongst the best explored liquid metal batteries. A simple and fast quasi-one-dimensional cell voltage model for such devices is presented. The…
Conductivity influence on interfacial waves in liquid metal batteries and related two-layer systems
Tom Weier, Ilmars Grants, Gerrit Maik Horstmann +5
Fluid flows in liquid metal batteries can be generated by a number of effects. We start with a short overview of different driving mechanisms and then address questions specific to…
Effects of current distribution on mass transport in the positive electrode of a liquid metal battery
Paolo Personnettaz, Steffen Landgraf, Michael Nimtz +2
Liquid metal electrodes are one of the key components of different electrical energy storage technologies. The understanding of transport phenomena in liquid electrodes is mandator…
Modeling discontinuous potential distributions using the finite volume method, and application to liquid metal batteries
Norbert Weber, Steffen Landgraf, Kashif Mushtaq +5
The electrical potential in a battery jumps at each electrode-electrolyte interface. We present a model for computing three-dimensional current and potential distributions, which a…
Electromagnetically driven convection suitable for mass transfer enhancement in liquid metal batteries
Norbert Weber, Michael Nimtz, Paolo Personnettaz +2
Liquid metal batteries (LMBs) were recently proposed as cheap large scale energy storage. Such devices are urgently required for balancing highly fluctuating renewable energy sourc…
