We mourn the loss of our colleague and friend, Prof. Dr.-Ing. Robert Stieglitz, who passed away unexpectedly. The Institute of Thermal Energy Technology and Safety (ITES) can look back on a long journey together with Robert Stieglitz, which began back in January 1991 when he joined the Institute, then still called the "Institute of Applied Thermo- and Fluid Dynamics", where he completed his doctorate in 1994 with a thesis on "Magnetohydrodynamic flows in single- and multi-channel deflections". Robert was a thoroughly creative engineer and passionate scientist. He had pursued his path with diligence, dedication and unwavering determination.

The article "Numerical and experimental analysis of magneto-convective flows around pipes" was published in the journal Fusion Engineering and Design. 

Detail: Liquid metals play an important role as breeding material and coolant for applications in future fusion power plants. The article examines the influence of thermoelectric effects on measurements of the electrical potential distribution in magneto-convective flows.

In the International Journal of Multiphase Flow the article "Subcooled forced convection boiling flow measured using high-resolution techniques at the COSMOS-L facility and accompanying CFD simulation employing an interface-tracking scheme" by F. Kaiser; Y. Sato and St. Gabriel was published.

RESIS

At the DVGW event on 12 and 13 March, DVGW Kongress GmbH: Wasser, which will deal intensively with the topic of "Resilience and security of supply in the public water supply", Dr. S. S. Ottenburger (Head of the RESIS department) will give a presentation entitled "More resilience through the use of digital twins". Against the background of emerging challenges and new risks for the water supply in an era of transformation and climate change, the key role of digital twins will be explained: A targeted use of digital twins makes it possible to identify sustainable measures to increase the resilience of water supply systems.

KALLA

The EU project RISEnergy (Research Infrastructure Services for Renewable Energy) starts on 1 March 2024. As part of the project, 84 renewable energy technology infrastructures will be available for use by European and non-European researchers.  These include the Karlsruhe Liquid Metal Laboratory, which is researching on high-temperature heat storage systems.

MHD

The article "Geometric optimization of electrically coupled liquid metal manifolds for WCLL blankets" by Leo Bühler and Chiara Mistrangelo was published in the journal IEEE Transactions on Plasma Science.

Details: Liquid metals play an important role as breeding material and coolant for applications in future fusion power plants. In the article, electrically coupled magnetohydrodynamic flows in the manifolds of a water-cooled test blanket for ITER are investigated and their geometry is optimized so that all breeder units are uniformly flowed through.

MHD

The article "MHD flows in curved pipes under a non-uniform magnetic field" by Chiara Mistrangelo and Leo Bühler was published in the journal IEEE Transactions on Plasma Science.

Detail: Liquid metals play an important role as breeding material and coolant for applications in future fusion power plants. The article investigates flows of liquid metals in double elbows, such as those planned in the shield block behind the water-cooled test blanket in ITER. Remarkable are high velocities in thin internal shear layers around a slow flow core.

„Computational fluid dynamics with OpenFOAM“

The format of the course allows a very flexible participation!

The course consists of four parts, each extending over two days. During day1, participants receive videos of the lectures, slides, and do the proposed exercises. During day2, teachers are available at any time for a one-to-one discussion via Zoom meeting to solve issues related to exercises and answer questions. The course will be held in English.
Objective: The purpose of the course is to acquire the knowledge and practical skills necessary to use the software OpenFOAM.
