Liquid metal multiphase flows

Multiphase flows play an important role in a number of technological processes in metallurgical and chemical industries. Gas bubbles are injected into liquid baths in order to stirr the fluid, because often times a better homogeneization (temperature, concentration) or the generation of a distinct flow structure is desired. One has to look for suitable methods to control the properties of such kind of flows. The utilization of magnetic fields seems to be an attractive way to affect the spatial distribution of bubbles or the momentum transfer between the gas and the liquid. On the other hand it is necessary to look for new measurements methods that can be used in such multiphase flows that include opaque liquid metals.

Elektromagnetic Se­paration

Electromagnetic fields enable contactless se­paration of material mixtures using
differences in the magnetic or electrical material properties. The task is to develop promising approaches for the successful application of electromagnetic methods for process control and material processing.

Removal of inclusions in liquid metals by flotation

The removal of non-metallic inclusions from liquid metal alloys by means of gas bubbles is important to ensure clean and high-quality structural materials. The project aims on a bet­ter understanding of interactions, e.g. collision and attachment, between bubbles and inclusions.

Liquid metal multiphase flows

Multiphase flows with a compressible disperse phase, i.e. gas bubbles, are a major challenge for research and technology development as they tend to form ­very complex flow patterns. Measurements in liquid metals are challenging, but, indispensable because of distinct differences in material properties compared to water.
