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.

MHD

The article "Experimental investigation of MHD flows in a WCLL TBM mock-up" was published in the journal Fusion Engineering and Design.

Details: Liquid metals play an important role as breeding material and coolant for applications in future fusion power plants. In this work, magnetohydrodynamic liquid metal flows in a test blanket for the ITER fusion reactor are investigated experimentally. The focus of this publication is on the measurement of the pressure distribution in strong magnetic fields.

Podcast "Heat storage technologies and their potential"

In the “Messepodcast”, Klarissa Niedermeier talks about the potential applications of heat storage systems and the research at the Karlsruhe Liquid Metals Laboratory. Available on Spotify and Apple Podcasts.

Effective incident and outage management is becoming increasingly important alongside cyber defense. Operational resilience includes real-time measures to minimize damage and maintain operations during resource bottlenecks and infrastructure failures. Due to growing complexity, digital twins, simulations and artificial intelligence are becoming increasingly important. Digitalization and AI promote agile resilience and should be integrated as early as the infrastructure planning stage.

ITES-H2

The annual spring meeting of the IEA Hydrogen TCP, Task 43 - Safety and RCS of Large Scale Hydrogen Energy Applications, took place at the Institute of Thermal Energy Technology and Safety in the week of April 9-12, 2024.

MHD

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.

„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.
