Within ARC CBBC, I wish to accomplish…

Together with experts in and outside my group I would like to work on a novel, green, carbon-free energy carrier: metal fuels. The key idea is that energy is stored in metal powders, which have a much higher energy density compared to e.g. lithium ion batteries or hydrogen. When these metals are burned, the stored energy is released. The resulting metal oxide powders need to be captured and regenerated into metal powders using green electricity. Our research is footed on extensive experience in the area of both combustion and multiphase (powder) flow.

In my scientific career, I am most proud of…

… my ability to combine knowledge on complex multiphase flow modeling and experimentation. This is nicely illustrated by my work on bubble columns, which is used by researchers worldwide as a benchmark test case for bubbly flow modelling. It is often referred to as “the Deen case”. My work on bubble columns was also recognized through an ERC starting grant. I’m also proud of my work on CFD-DEM simulations. My review paper on this work has meanwhile been cited over 350 times and is the second best cited paper out of 703 in Chemical Engineering Science in 2007.
