The research group "Simulation Sciences" (SiSc for short) works on the numerical analysis and optimization of membrane-based processes. Current work investigates the fouling behavior on and in porous membranes, thermocatalytic and electrochemical synthesis in membrane reactors, the capacitive separation of salts using electrodialysis, and the manufacture of artificial neural networks using membrane resistors.

The overall goal of the model-based investigations is to answer fundamental questions about mass transport and flow conditions in the systems under consideration. Furthermore, the SiSc group uses machine learning (ANNs - Artificial neuronal networks) to optimize processes purposefully. Thus, the simulations can contribute to the validation of experimental data, but also to the optimization of experiments.

The following simulation methods are used in the group:

  • Numerical flow simulations (CFD)
  • Multi-phase simulations (CFD-DEM)
  • Process modeling and optimization (NLP, MINLP, ANNs)

The SiSc group has knowledge in different simulation software:

  • Aspen Custom Modeler
  • Aspen Plus
  • Aspherix (DEM)
  • COMSOL Multiphysics
  • CFDEM-Coupling
  • EnPEn (developed at the Chair)
  • GAMS
  • Liggghts (DEM)
  • MatLab
  • OpenFoam
