Electrocapillary two-phase flow in a confined cavity is studied. The flow configuration corresponds to a classical experiment of Melcher and Taylor. It is shown that the computed streamlines of the flow of the heavier liquid (corn oil) qualitatively

The lowest swirling wave mode arising in upright circular cylinders as a response to circular orbital excitation has been widely studied in the last decade, largely due to its high practical relevance for orbitally shaken bioreactors. Our recent theo

We propose a new theoretical model for metal pad roll instability in idealized cylindrical reduction cells. In addition to the usual destabilizing effects, we model viscous and Joule dissipation and some capillary effects. The resulting explicit form

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 the metal pad role instabilities in three-layer systems. We focus on

We present a new theoretical model describing gravity-capillary waves in orbitally shaken cylindrical containers. Our model can account for both one-layer free surface and two-layer interfacial wave systems. A set of modal equations for irrotational

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 deformation of the Li-salt interface. We find that there always exists a crit

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 hydrodynamical model for liquid metal batteries. It is intended to shed new lig

Large-scale flow structures were measured in a rectangular Rayleigh-Benard sample of equal length and height of 10 cm and a depth of 2.5 cm . The working fluid was water at a Prandtl number of Pr = 6.9 . Aiming to capture flow structures to their ful

Liquid metal batteries (LMBs) are discussed today as a cheap grid scale energy storage, as required for the deployment of fluctuating renewable energies. LMBs incorporate stratified three-layer fluid systems consisting of two liquid metal electrodes

Liquid metal batteries are possible candidates for massive and economically feasible large-scale stationary storage and as such could be key components of future energy systems based mainly or exclusively on intermittent renewable electricity sources
