Abstract:
We report a general numerical strategy for the simulation of the hydrodynamics and mass transfer at a wall tube electrode based on finite element modeling. Previous empirical and approximate analytical treatments predicting the current as a function of flow rate and cell geometry are critically assessed and shown to have limited general applicability. Good agreement between experiment and simulation is found, providing a rigorous basis for future work with these electrodes.
