Transport processes at interfaces
The new department established in Oct. 2016 (Head: Prof. Dr. Kerstin Eckert):
- analyzes multi-scale transport phenomena at different sorts of interfaces, e.g. liquid-liquid interfaces
- performs experiments and simulations to investigate the flow phenomena and related instabilities of / at interfaces
Flotation
The focus is on model experiments to study particle attachment depending on the hydrodynamics in the flotation cell on both micro- and mesoscale. For this purpose, advanced PIV methods and interferometry are used.

Electrochemical processes
Gas-evolving electrodes and electrodeposition processes are in the focus of our works performed in close collaboration with IFW Dresden. Our particular interest is on the contactless enhancement of mass transport by means of a magnetohydrodynamic convection.

Magnetic separation
Commercial magnetic separators treat successfully para- and ferromagnetic particles up to sizes of 0.1…0.5 mm. We work on magnetic separation techniques for finer particles and ionic species.

Dendritic solidification
We study the evolution of dendrites during the solidification of metallic melts.Phase-field simulations combined with experimental results are employed to better understand transient solidification conditions and coarsening processes.

Foam flow
The flowing behavior of wet aqueous foam is investigated, combining experimental and numerical methods. Special focus lies on the interaction between flow and liquid content of the foam.

Marangoni convection at droplets and bubbles
Mass transfer across interfaces is frequently accompanied by hydrodynamic instabilities, such as Marangoni or Rayleigh instabilities. Their study forms one focus of our works at TUD.
