**Your Job**:
The focus of this Master’s thesis aims to generate a variety of physical and artificially constructed porous structures and assess whether the properties of these synthetic models can statistically represent those of physical structures in electrochemical cells. Key properties under investigation include two-phase flow behavior, conductivity, and geometrical characteristics such as pore and particle size distributions. Physical structures will be sourced from existing databases and X-ray tomography imaging. The study will compare pore network models and custom two-phase flow CFD approaches, implemented in OpenFOAM and coupled with electrochemical processes, against experimental data to evaluate model accuracy and reliability. The insights gained will enhance the precision of macro-homogeneous models, such as those simulated within openFuelCell2, expanding its capabilities. Furthermore, this work will establish a comprehensive database for future studies, facilitating the integration of AI techniques to optimize porous media design and performance in electrochemical systems.
- Conduct literature research on multiphase flow dynamics.
- Create digital models of synthetic porous structures to enhance physical data analysis and interpretation.
- Employ pore network models to characterize the properties of these porous structures.
- Compare findings with experimental data and results from two-phase CFD simulations.
- Integrate insights into the OpenFOAM framework, openFuelCell2, as part of the workflow.

**Your Profile**:

- Undergraduate education with excellent grades in Material Science, Physics, Engineering, Chemistry or a related field
- Good knowledge of fluid mechanics, thermodynamics and/or electrochemistry
- Demonstrated experience in Computational Fluid Dynamics, C++, Linux, Python and OpenFOAM
- Willingness to learn and ability to think outside of the box
- Independent, self-motivated and responsible
