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…
Transient behaviour of electrovortex flow in a cylindrical container
Ke Liu, Frank Stefani, Norbert Weber +2
This study is a continuation of the combined experimental and numerical investigation [1] of the flow of the eutectic GaInSn alloy inside a cylindrical vessel exposed to a constant…
Anode-metal drop formation and detachment mechanisms in liquid metal batteries
Sabrina Bénard, Norbert Weber, Gerrit Maik Horstmann +2
We study numerically localised short circuits in Li||Bi liquid metal batteries. In the prototype of a classical, three liquid-layer system, we assume a perceptible local deformatio…
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…
Numerical and Experimental Investigation of Electro-Vortex Flow in a Cylindrical Container
K. Liu, F. Stefani, N. Weber +2
In a cylindrical container filled with an eutectic GaInSn alloy, an electro-vortex flow (EVF) is generated by the interaction of a non-uniform current with its own magnetic field.…
Measurement of interfacial wave dynamics in orbitally shaken cylindrical containers using ultrasound pulse-echo techniques
Gerrit Maik Horstmann, Markus Wylega, Tom Weier
We present a novel experiment on interfacial wave dynamics in orbitally shaken cylindrical vessels containing two- and three fluid layers. The experiment was designed as a hydrodyn…
Competing forces in liquid metal electrodes and batteries
Rakan F. Ashour, Douglas H. Kelley, Alejandro Salas +3
Liquid metal batteries are proposed for low-cost grid scale energy storage. During their operation, solid intermetallic phases often form in the cathode and are known to limit the…
Fluid Mechanics of Liquid Metal Batteries
Douglas H. Kelley, Tom Weier
The design and performance of liquid metal batteries, a new technology for grid-scale energy storage, depend on fluid mechanics because the battery electrodes and electrolytes are…
Coupling and stability of interfacial waves in liquid metal batteries
Gerrit Maik Horstmann, Norbert Weber, Tom Weier
We investigate the interfacial wave coupling dynamics in liquid metal batteries and their effects to the battery's operation safety. Similar to aluminum reduction cells, liquid met…
Electro-vortex flow simulation using coupled meshes
Norbert Weber, Pascal Beckstein, Vladimir Galindo +2
A numerical model for simulating electro-vortical flows in OpenFOAM is developed. Electric potential and current are solved in coupled solid-liquid conductors by a parent-child mes…
The DRESDYN project: planned experiments and present status
Frank Stefani, Sven Eckert, Gunter Gerbeth +5
The Dresden sodium facility for dynamo and thermohydraulic studies (DRESDYN) is a platform for large-scale liquid sodium experiments devoted to fundamental geo- and astrophysical q…
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…
The Tayler instability at low magnetic Prandtl numbers: between chiral symmetry breaking and helicity oscillations
Norbert Weber, Vladimir Galindo, Frank Stefani +1
The Tayler instability is a kink-type, current driven instability that plays an important role in plasma physics but might also be relevant in liquid metal applications with high e…
The influence of current collectors on Tayler instability and electro-vortex flows in liquid metal batteries
N. Weber, V. Galindo, J. Priede +2
The Tayler instability is a kink-type flow instability which occurs when the electrical current through a conducting fluid exceeds a certain critical value. Originally studied in t…

Norbert Weber, Vladimir Galindo, Frank Stefani +1
The use of liquid metal batteries is considered as one promising option for electric grid stabilisation. While large versions of such batteries are preferred in view of the economi…
How to circumvent the size limitation of liquid metal batteries due to the Tayler instability
Frank Stefani, Tom Weier, Thomas Gundrum +1
Recently, a new type of battery has been proposed that relies on the principle of self-assembling of a liquid metalloid positive electrode, a liquid electrolyte, and a liquid metal…
