CFD-based Shape Optimization of Structured Packings for Enhancing Separation Efficiency in Distillation
Sebastian Blauth, Dennis Stucke, Mohamed Adel Ashour +3
Free-form shape optimization techniques are investigated to improve the separation efficiency of structured packings in laboratory-scale distillation columns. A simplified simulati…
A Novel Deflation Approach for Topology Optimization and Application for Optimization of Bipolar Plates of Electrolysis Cells
Leon Baeck, Sebastian Blauth, Christian Leithäuser +2
Topology optimization problems usually feature multiple local minimizers. To guarantee convergence to local minimizers that perform best globally or to find local solutions that ar…
Continuous Synthesis of Diazo Acetonitrile: From Experiments to Physical and Grey-Box Modeling
Marco Baldan, Sebastian Blauth, Dušan Bošković +6
Diazo compounds are gathering interest for their potential in promoting greener synthesis routes. We investigate, at a lab-scale, the continuous synthesis of diazo acetonitrile (DA…
Multi-Criteria Shape Optimization of Flow Fields for Electrochemical Cells
Sebastian Blauth, Marco Baldan, Sebastian Osterroth +7
We consider the shape optimization of flow fields for electrochemical cells. Our goal is to improve the cell by modifying the shape of its flow field. To do so, we introduce simula…
Topology Optimization for Uniform Flow Distribution in Electrolysis Cells
Leon Baeck, Sebastian Blauth, Christian Leithäuser +2
In this paper we consider the topology optimization for a bipolar plate of a hydrogen electrolysis cell. We present a model for the bipolar plate using the Stokes equation with an…
Optimal Control of the Sabatier Process in Microchannel Reactors
Sebastian Blauth, Christian Leithäuser, René Pinnau
We consider the optimization of a chemical microchannel reactor by means of PDE constrained optimization techniques, using the example of the Sabatier reaction. To model the chemic…
Shape Sensitivity Analysis for a Microchannel Cooling System
Sebastian Blauth, Christian Leithäuser, René Pinnau
We analyze the theoretical framework of a shape optimization problem for a microchannel cooling system. To this end, a cost functional based on the tracking of absorbed energy by t…
Model Hierarchy for the Shape Optimization of a Microchannel Cooling System
Sebastian Blauth, Christian Leithäuser, René Pinnau
We model a microchannel cooling system and consider the optimization of its shape by means of shape calculus. A three-dimensional model covering all relevant physical effects and t…
Identification of the Blood Perfusion Rate for Laser-Induced Thermotherapy in the Liver
Matthias Andres, Sebastian Blauth, Christian Leithäuser +1
Using PDE-constrained optimization we introduce a parameter identification approach which can identify the blood perfusion rate from MR thermometry data obtained during the treatme…
Approximate Controllability of Linearized Shape-Dependent Operators for Flow Problems
Christian Leithäuser, René Pinnau, Robert Feßler
We study the controllability of linearized shape-dependent operators for flow problems. The first operator is a mapping from the shape of the computational domain to the tangential…
A Numerical Approach to Shape Optimization with State Constraints
Christian Leithäuser, René Pinnau, Robert Feßler
We present a general numerical approach to shape optimization with state constraints for 2-dimensional geometries, without relaxing the constraints. To do this we reformulate the p…
