Multiphase Flow Modelling of Electrochemical Systems: an analytical approach

The primary objective of this work is to provide new analytical models to support the theoretical understanding of multiphase flows in various electrochemical systems. Most of the previous works in this field use either experiments or numerical simulations to understand the hydrodynamics of the multiphase flows. In this thesis, various new...

An analytical model for the velocity and gas fraction profiles near gas-evolving electrodes

Understanding multiphase flow close to the electrode surface is crucial to the design of electrolyzers, such as alkaline water electrolyzers for the production of green hydrogen. Vertical electrodes develop a narrow gas plume near their surface. We apply the integral method to the mixture model. Considering both exponentially varying and step...
