This PhD project offers a unique opportunity to explore fundamental aspects of multiphase phenomena that occur in electrolyzer cells and to develop numerical tools helping to analyze them and improve their performance.
In an electrolyzer cell, multiphase flow occurs at different scales, from macroscales to nanoscales. The flow path in electrolyzers is in the cm range in the feeding lines, mm scale in the flow distributor section towards the channels, and in the channels. Above the channels, the transport layer is composed of microporous and occasionally nanoporous regions through which the flow arrives at the electrodes.
A proper understanding of multiphase flow at each scale is essential for the optimization of the flow and bubbles generation in electrolyzer cells.
Hence, the project aims to focus on macroscopic modelling, considering all relevant chemical and physical processes in the different cell regions, to model the coexisting of different flow regimes and the transition from isolate bubbles to regions of pure gas with very high bubble-phase volume fraction.
While there are several methods to simulate the gas-liquid flows, the Euler-Euler approach and the population balance modelling coupled with CFD stands out as particularly robust and advantageous for large-scale industrial applications due to its computational efficiency and robustness to investigate bubbles evolution and dynamics in the electrolysis cell/stack more comprehensively needed for the optimization of the performance.
The developed tool will be used to investigate the impact of various factors on the performance of the gas/liquid two-phase transport process and to propose novel designs to increase the efficiency.
