DOI: 10.1002/bit.28869
Abstract: Large‐scale fermentations (»100 m³) often encounter concentration gradients which may significantly affect microbial activities and production performance. Reliably investigating such scenarios in silico would allow to optimize bioproduction. But related simulations are very rare in particular… read more here.

DOI: 10.1016/j.powtec.2019.05.012
Abstract: Abstract Particle-resolved CFD simulations are widely used for the predictions of particle-scale flow, transport processes and chemical reactions. However, the effect of turbulence models used in such simulations is not quantitatively established. In the present… read more here.

DOI: 10.1093/mnras/stx1470
Abstract: In the Solar System, asteroids and Kuiper belt objects as well as comets are remnant planetesimals from the time of planet formation. Interactions between solids and gas inside a protoplanetary disc can, e.g. through the… read more here.
