Model-based computational study of reactive fluid systems using transfer operator methods
Anja Göbel, Anna Klünker, Alexandra von Kameke +1
In many industrial applications one aims for the design of efficient chemical reactions. This is often done using experimental analysis of the reactors in combination with numerica…
Can we live Danckwerts' dream? Mixing Analysis in a Baffled Stirred Tank Reactor Based on 4D-Particle Tracking Experiments
Eike Steuwe, Thanh Tung Thai, Christian Weiland +5
We present an experimental investigation of mixing dynamics within a laboratory-scale 3-liter stirred tank reactor (STR) equipped with two Rushton turbines and three baffles. Using…
Tracking in-silico Lagrangian sensors in a lab-scale stirred tank reactor
Vamika Rathi, Fatima Sehar, Finn Sommer +4
Lagrangian sensors have shown promise to improve operator awareness of conditions inside a chemical reactor but three-dimensional tracking remains a mostly unsolved challenge. We e…
Relevance of the Basset history term for Lagrangian particle dynamics
Julio Urizarna-Carasa, Daniel Ruprecht, Alexandra von Kameke +1
The movement of small but finite spherical particles in a fluid can be described by the Maxey-Riley equation (MRE) if they are too large to be considered passive tracers. The MRE c…
lcs4Foam -- An OpenFOAM Function Object to Compute Lagrangian Coherent Structures
Constantin Habes, Alexandra von Kameke, Mohammed Elwardi Fadeli +1
To facilitate the understanding and to quantitatively assess the material transport in fluids, a modern characterisation method has emerged in fluid dynamics in the last decades fo…
Effect of filter kernel on scale-energetics of near-wall turbulent structures
Daniel Feldmann, Mohammad Umair, Marc Avila +1
Inter-scale energy fluxes, , are widely used as a diagnostic tool to analyse energy transfer across length scales, , in turbulence data. Here, we investigate how the choice…
