Dr. Bieberle – HZDR

Helmholtz-Zentrum Dresden-Rossendorf

The Helmholtz-Zentrum Dresden-Rossendorf is a member of the Helmholtz Association of German Research Centres pursuing new insights that will allow us to maintain and improve all of our lives. That’s why the HZDR conducts research in the sectors health, energy, and matter in Dresden and at three other locations. Three of our five large-scale facilities are also available to external guests from around the world to help answer the decisive questions of our society.

Institute of Fluid Dynamics

The Institute of Fluid Dynamics was founded in 2012 within the Helmholtz-Zentrum Dresden-Rossendorf. It is emerged from the Institute of Safety Research, which was founded in 1992. The research topics of the institute are embedded in the research fields Matter and Energy.

Scientific Profile

The institute’s work aims for the exploration of dynamic systems in the fields of thermo-fluid dynamic as well as in magnetohydrodynamics. For this purpose, evaluation models for the process analysis are being developed and validated through high-level experiments. The research area comprises thermo-fluid dynamic phenomena as well as chemical reaction kinetics and neutron kinetics for the description of heat sources. Magnetohydrodynamics research is engaged in the basics of interaction of magnetic fields with electrically conductive liquids and the application of customised magnetic fields for the process optimisation in metallurgy, crystal growth, as well as electrochemistry. The institute is in charge of several experimental facilities, which form the basis of our investigations. For the experiments we are not only using industrial operational equipment but also the in-house development of high valuable measurement equipment plays an important role.

Scientific Projects with GPU background

Ultrafast electron beam X-ray tomography

The ultrafast X-ray tomography system ROFEX enables imaging of dynamic processes such as gas-solid and gas-liquid two-phase flows with a temporal resolution of up to 8000 fps and a spatial resolution of down to 1 mm.

For the investigation of multi-phase flows, which occur in a variety of technical processes, an ultrafast X-ray tomography system has been developed in the department of experimental thermal fluid dynamics, headed by Prof. Uwe Hampel. It reaches frame rates of up to 8000 images per second and together with a spatial resolution of about 1 mm it allows a very detailed analysis of dynamic flow structures. Thus, it helps to optimize the respective processes. Furthermore, it provides an extensive data basis for the validation of computational fluid dynamics codes, which can in turn predict the behaviour of the flow more accurately.

A system with such a high data acquisition rate would strongly benefit from an accelerated tomographic image reconstruction concept based on GPU programming. If online reconstruction was possible, further applications like inline non-destructive testing and process control could be developed. The project of image reconstruction is headed by Dr. Martina Bieberle.
