The large-scale flow structure and the turbulent transfer of heat and momentum are directly measured in highly turbulent liquid metal convection experiments for Rayleigh numbers varied between $4 \times 10^5$ and $\leq 5 \times 10^9$ and Prandtl numb

Dispersed two phase flows cover a wide range of natural phenomenon and technological applications. When studying such complex systems, having access to the velocities of both phases is necessary to fully understand their dynamics. In experiments, ine

Spherical Couette flows in liquid metals are a suitable candidate for generating magnetic dynamo states in the laboratory. However, results in our 3 meter diameter experiment have shown that an enhancement of the flow's helicity is likely required. P

The effects of a vertical static magnetic field on the flow structure and global transport properties of momentum and heat in liquid metal Rayleigh-B\'enard convection are investigated. Experiments are conducted in a cylindrical convection cell of un

In this article, the theoretical model on heat and momentum transfer for Rayleigh-B\'enard convection in a vertical magnetic field by Z\"urner et al. (Phys. Rev. E 94, 043108 (2016)) is revisited. Using new data from recent experimental and numerical

We report velocity measurements in a vertical turbulent convection flow cell that is filled with the eutectic liquid metal alloy gallium-indium-tin by the use of local Lorentz force velocimetry (LLFV) and ultrasound Doppler velocimetry (UDV). We demo

The scaling theory of Grossmann and Lohse (J. Fluid Mech. 407, 27 (2000)) for the turbulent heat and momentum transfer is extended to the magnetoconvection case in the presence of a (strong) vertical magnetic field. The comparison with existing labor

Measuring the flow velocity in hot, chemically aggressive and opaque melts is a challenging task even for today’s measurement techniques. The contactless inductive flow tomography (CIFT) could provide a solution by applying magnetic fields to an el

A novel measurement system to determine the surface position and topology of liquid metals is presented. It is based on the induction of eddy currents by a time-harmonic magnetic field and the subsequent measurement of the resulting secondary magneti
