“Multiphase and reactive flows are all around us. To make processes and equipment more sustainable we need to get the fundamentals right.”
Research profile
Niels Deen is a Full Professor and Chair of the Power & Flow group in the Department of Mechanical Engineering at Eindhoven University of Technology (TU/e). Niels’ expertise is largely in the areas of process technology, multiphase reactors, computational fluid dynamics and experimental fluid dynamics.
His research is concerned with the development of computational and experimental techniques for the study of multiphase reactors. In particular, his research interests encompass the reduction of fine iron powder as part of the iron power cycle, bubble dynamics in hydrogen production and multiphase and reactive flow modeling for green steel making.
Academic background
Niels Deen obtained his PhD from Aalborg University, Esbjerg. From 2001 until 2010, he worked as an assistant professor at the University of Twente in The Netherlands. From 2010 until 2015, he worked as an associate professor in the TU/e Multiphase Reactors Group. In 2010, Niels received a Starting Grant from the European Research Council (ERC) to work on micro-structured bubble column reactors. He has collaborated with all the major chemical industries in the Netherlands. Niels served as an Editor of Elsevier publication Chemical Engineering Science from 2014-2022. From 2009-2018 he co-chaired the contact group on Multiphase Flow of the J.M. Burgerscentrum (JMBC). He was a member of the management team of the Eindhoven Institute for Renewable Energy Systems (EIRES) from 2020-2024.
Since 2016 Niels is a full professor and head of the Power and Flow group. He is a principal investigator of EIRES. Since 2023 he is a member of the management team of the JMBC. Since 2024 he is Vice-Dean of the Department Mechanical Engineering.
