Magnetohydrodynamik

Die Magnetohydrodynamik (MHD) ist ein spezielles Fachgebiet der Thermohydraulikforschung und befasst sich mit der Wechselwirkung zwischen elektrisch leitfähigen Fluiden und elektromagnetischen Feldern. Die Forschung am HZDR offenbart eine große Bandbreite an Grundlagen- und angewandten Forschungen, die sich von der Hochtemperatur-Energieübertragung, neuen Flüssigmetallbatterien, der Herstellung von Solar-Silizium, einer CO2-freien Wasserstofferzeugung, dem Einsatz von Flüssigmetalltargets in Neutronenquellen und Transmutationsanlagen, dem Gießen von Stahl und Leichtmetallen, Schweiß- und Lötprozessen, bis zu grundlegenden Laborexperimenten mit Bezug zu flüssigmetallgekühlten Systemen, der Materialverarbeitung oder der Geo- und Astrophysik erstreckt.

Geo/Astrophysics

Cosmic magnetic fields are generated by the hydromagnetic dynamo effect and play a crucial role in cosmic structure formation by means of the magnetorotational instability. Liquid metal experiments may help to understand those fundamental processes

Model experiments for metallurgy and crystal growth processes

The optimization of processes in metallurgy or in the crystallization of semiconductor materials with regard to product quality and energy efficiency requires a profound understanding of the flow processes in the melts.

Measurement techniques for liquid metals

The knowledge of velocity structures or of the gas distribution in liquid metals is of great interest in laboratory experiments as well as in industrial applications. The opaqueness of those fluids prevents the use of well established optical methods. Additionally, the corrosiveness and the high temperatures are challenges for measurement techniques.

Solidification of metal alloys

Convective transport plays an important role in solidification processes. The application of electromagnetic stirring in solidifying melts is attractive because there is an active influence on the microstructural characteristics and thus on the mechanical properties via a completely contactless control of the flow.

Liquid metal multiphase flows

Liquid metal two-phase flows are of particular importance for many processes in metallurgy and metal casting. For example, the secondary-metallurgical treatment of liquid steel relies on the injection of purge gas for improving the steel cleanliness. Objectives are the enhancement of mixing and homogenization and the se­paration of inclusions by flotation.
