EVT-ITBA

A joint lecture course on geothermal energy was held in Buenos Aires as part of the KIT-ITBA Double Degree Master's program. In the DAAD-funded project, KIT mechanical engineering students can be sent to Buenos Aires for a semester at the Instituto Tecnologico de Buenos Aires (ITBA) as part of a scholarship. The subsequent Master's thesis can take place in Argentina or Germany and the students receive the corresponding degree in Argentina in addition to the German Master's degree.

KIT

In the context of energy systems, cities and climate change, an international and interdisciplinary collaboration has resulted in the Nature Sustainability Paper entitled 'Sustainable urban transformations based on integrated microgrid designs' together with colleagues from the University of North Carolina at Charlotte (UNCC) and the National Renewable Energy Lab (NREL), which will be available from July 16 at https://www.nature.com/articles/s41893-024-01395-7.

EVT-ITBA

In June, ITES welcomed 21 participants to the certified waste heat consultant (m/f/d) course as part of their second day of attendance.

The course is offered by the Waste Heat Competence Center and Akademie der Ingenieure AkadIng GmbH. The course explains the procedure for waste heat consulting in companies in more detail. The attendance day at ITES was divided into various lectures on the work on waste heat utilization at ITES, a tour of various research facilities and technical presentations from industry and research by external lecturers.  

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.

Comparison of two models for the calculation of closed evaporative coolers

The task is to map the models in a software (Excel VBA, Matlab, ...) and to determine and discuss the limits of the first approach by means of quasi-stationary simulation calculations.

The results should also be used to dimension an experiment on the basis of which the models can be validated in subsequent work.

„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.
