Flow research on the outskirts of space: Experiments in weightlessness isolate classic diffusion phenomenon - Helmholtz-Zentrum Dresden-Rossendorf, HZDR

For years, various models have been developed to describe an important class of mixing effects that occur, for example, in the flow in a chemical reactor. Experimental validation, however, has lagged far behind due to the superimposition of gravity effects. A European research team involving the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and partners at the University of Szeged (Hungary) and Université libre de Bruxelles (ULB, Belgium) has now closed this gap with experiments conducted under weightlessness. The researchers recently published their results in the Nature journal npj Microgravity (DOI: https://doi.org/10.1038/s41526-024-00390-8).
