Analysis of inlet and gap effect in hydrodynamics and mass transport performance of a multipurpose electrochemical reactor: CFD simulation and experimental validation

This work deals with the reaction environment analysis (hydrodynamic and mass transport characterization) inside the flow channel of a parallel plate electrolyzer. Different electrode gap and inlet configurations were tested using computational and experimental techniques. Computational methods are based on numerical solution of mathematical models that describe fluid dynamics inside reactor meanwhile, experimental characterization was carried out by means of residence time distribution (RTD) and limiting current tests.
