The University of Luxembourg is an international research university with a distinctly multilingual and interdisciplinary character. The University was founded in 2003 and counts more than 6,700 students and more than 2,000 employees from around the world.

The University’s faculties and interdisciplinary centres focus on research in the areas of Computer Science and ICT Security, Materials Science, European and International Law, Finance and Financial Innovation, Education, Contemporary and Digital History.

In addition, the University focuses on cross-disciplinary research in the areas of Data Modelling and Simulation as well as Health and System Biomedicine. Times Higher Education ranks the University of Luxembourg #3 worldwide for its “international outlook,” #20 in the Young University Ranking 2021 and among the top 250 universities worldwide.

The Faculty of Science, Technology and Medicine (FSTM) contributes multidisciplinary expertise in the fields of Mathematics, Physics, Engineering, Computer Science, Life Sciences and Medicine. Through its dual mission of teaching and research, the FSTM seeks to generate and disseminate knowledge and train new generations of responsible citizens, in order to better understand, explain and advance society and environment we live in.

The University of Luxembourg (UL) invites applications for a post-doctoral position (f/m/d) as part of an industry collaboration funded by the FNR Bridges funding instrument

Research Framework

In order to deal with critical fuels that otherwise have to be disposed of, co-firing of these fuels in existing combustion plants is an economic alternative. However, these critical fuels distinguish themselves significantly from the fuel the combustion technology was designed for and therefore, may have a negative impact on operation. Rather than investing into cost-intensive and time-consuming experimental campaigns, a multi-physics digital twin in a high-performance computing environment allows exploring various co-firing scenarios in a cost-effective manner.

Combining multi-physics i.e. motion and thermal conversion of solid fuels with a reacting gas phase requires a smart partitioning technology. It is the key technology to fast multi-physics digital twin simulation technology and paves the road to innovative approaches for co-firing of critical fuels.
