Arbeits- und Forschungsschwerpunkte, Spezialkenntnisse

Methods:
- General: Multiphysics and Multiscale simulations of technical systems and processes. Depending on the problem, different modeling approaches are applied (e.g. analytical models, system simulation with lumped parameters, finite element and finite volume method in 1D, 2D and 3D) using own implementations as well as commercial software packages (e.g. GeoDict, Comsol Multiphysics, ANSYS, OpenFOAM, Matlab/Simulink etc.).
- Digital Microstructure Design: Workflow for a digital design and optimization of porous materials. Microstructures are virtually varied and optimized based on stochastic digital microstructure twins, which are fitted to real tomography data. The impact of the virtual microstructure variation on the device-performance is predicted with an appropriate physical model. This approach has been successfully applied for solid oxide fuel cells (SOFC) and aerosolfilters and can easily be adapted to other applications.
- Multiscale approach: Real and virtual microstructure models are characterized based on 3D geometry data in an automated way (e.g. using cloud computing). The effective properties of the microstructures are then used as an input for a continuum Multiphysics model.
- Experimental calibration and validation: Very often, modelling and simulation are used together with experimental studies in order to calibrate and validate the models and to verify the design guidelines deduced from the simulations. Thus, the appropriate design, analysis and interpretation of experiments is often an important part of a successful modeling project.

Applications:
- Fuel cells: Solid oxide fuel cells (SOFC, especially novel material concepts for nickel-free electrodes), PEM fuel cells (membrane electrode assembly modelling and water management), electrochemical impedance spectroscopy
- Aerosolfilters: Design for low pressure drop and high filter efficiency of ceramic and polymer-based filters.
- Model-based development and optimization of fluidic dosing systems including electromagnetic, piezoelectric or pneumatic actuation. Control of the dosing by integrated flow measurement. Experience with low to very high viscous fluids.
- General: Analysis, modeling and simulation of technical systems and processes in a broad range of applications. Excerpt of additional experience from successfully completed modeling projects: Drop separation for low and high viscous fluids (two-phase flow CFD simulation), Brownian dynamics simulation of colloidal suspensions, model-based development of actuators (pneumatic, electromagnetic, voice-coil, piezoelectric) with system simulations and FEM-simulations, different modeling projects for sensors (flow sensor, electromagnetic and capacitive sensors), design and optimal placing of antennas (high frequency electromagnetic simulations), dynamic behavior of a cable cars (system simulation), waste gas treatment (CFD simulation) etc.
