Her project aims to investigate pore-scale fluid flow and mass transport in porous electrodes of redox flow batteries. For this purpose, a micro-scale modelling framework based on the Lattice Boltzmann (LB) method will be developed.
The framework will be used to analyze how redox flow batteries operate and to identify optimal pore and electrode structures that enable efficient electrolyte and electrical flow. In particular, electrode performance will be studied by examining mixing and species movement within the porous electrode.
Subsequently, the modelling approach will be applied to porous electrode microstructures reconstructed from X-ray computed tomography. The simulation results will be compared with experimental observations and used to parameterize key processes, such as how easily the electrolyte moves, mixes, and reacts inside the electrode.
Based on the pore-scale simulations and experimental comparisons, the developed model links electrode microstructure to effective pore-scale behavior and electrochemical performance. These results will support and complement the work of other doctoral researchers by providing physically grounded input for electrode prototyping, upscaling, and cell-level modelling. Overall, this collaborative approach will contribute to the design of high-performance redox flow battery electrodes.
