The programme of the annual meeting of the ProcessNet specialist groups Computational Fluid Dynamic, Mixing Processes and Agglomeration and Bulk Solids Technology 2022 includes three presentations by the IMS. The lectures deal with the mixing behaviour of stirred reactors, the following ability of different Lagrangian particles in the bioreactor flow and the simulation of Lagrangian particle trajectories in a 3 L stirred tank reactor.

The January issue of gwf Wasser/Abwasser published the results of Lisa Watters' master's thesis on the hydrodynamic optimisation of a large-scale pumping station to improve sand pumping characteristics.

In the winter semester 21/22, about 60 students of the Master's programme in Process Engineering tried their hand at designing multiphase reactors as part of a problem-based learning project. They presented and discussed the results of their designs in a symposium at the beginning of March.

At this year's annual meeting of the ProcessNet specialist groups, there will again be a presentation by the IMS. Felix Kexel will present his research results on the topic of Fluid Dynamics of Taylor Bubbles in Organic Solvents on 22.02.22.

The Institute of Multiphase Flows congratulates Mr. Jürgen Fitschen on passing his doctoral thesis.

Mr. Gürel presents the results of his masters project on the "Installation of a high-speed digitizer system for generation of non-monochromatic forcing signals for Faraday waves".

Mr. Jürgen Fitschen presents the results of his doctoral thesis about the "Hydrodynamic Characterization of Heterogeneities in Aerated Stirred Tank Reactors -From an Eulerian to a Lagrangian Perspective-"

Mr. Sampelli presents the results of his project work dealing with the "Effect of a Chemical Reaction on Grid Convergence of a Direct Numerical Simulation".

Mrs. Omar presents the results of her masters thesis dealing with the "Multi-objective optimisation of a flow-through open structure using the discrete adjoint method by means of numerical flow simulation".

The magazine article reports on the Institute's work on the efficient production of biotechnological/pharmaceutical products, such as the current vaccines for corona prevention. A small insight is given into how the scaling up from laboratory scale to production scale is done.
