Organization profile

Introduction / mission

"Multiphase and reactive flows are all around us. To make processes and equipment more sustainable we need to get the fundamentals right."

Organisational profile

Group Deen focuses largely in the areas of process technology, multiphase reactors, computational fluid dynamics and experimental fluid dynamics.

The research is concerned with the development of computational and experimental techniques for the study of multiphase reactors. This includes multiphase flow modeling of intensified contacting in bubble column reactors and multiphase processes in fluidized beds. Typical applications of this research include the automotive, food and chemical industries. One especially interesting potential application is metal fuels - metallic powders of order 10 µm - that are combusted/regenerated in a closed cycle and as such present a very attractive recyclable zero-carbon fuel option.
