Efficient Geometry Representation Strategies for the Shape Optimization of Profile Extrusion Dies
Jana Sasse, Maximilian Esser, Markus Mügge +1
The design of profile extrusion dies remains a challenging task due to the complex rheological behavior of polymer melts and the geometric intricacies of flow channels. Traditional…
Feasibility study for physics-informed direct numerical simulation describing particle suspension in high-loaded compartments of air-segmented flow
Otto Mierka, Raphael Münster, Henrik Julian Felix Bettin +2
The Archimedes Tube Crystallizer (ATC) employs air-segmented flow in coiled tubes to achieve narrow residence time distributions for continuous crystallization. Taylor and Dean vor…
Effective viscosity closures for dense suspensions in CSP systems via lubrication-enhanced DNS and numerical viscometry
Raphael Münster, Otto Mierka, Dmitri Kuzmin +1
Dense particle suspensions are promising candidates for next-generation Concentrated Solar Power (CSP) receivers, enabling operating temperatures above 800 degrees C. However, accu…
A Chimera domain decomposition method with weak Dirichlet-Robin coupling for finite element simulation of particulate flows
Raphael Münster, Otto Mierka, Dmitri Kuzmin +1
We introduce a new multimesh finite element method for direct numerical simulation of incompressible particulate flows. The proposed approach falls into the category of overlapping…
