A two-dimensional mathematical model has been developed to describe annular
electrochemical reactor performance. Multiple electrochemical reactions of
copper electrowinning from a chloride solution were evaluated to illustrat
e the usage of the model. The simulation includes the mass transport of ion
ic species and the associated electrochemical kinetics under the laminar fl
uid flow condition. The model predicts current distributions on the electro
des, conversion per pass (CPP), selectivity of copper as a function of the
applied potential, residence time, and anode to cathode diameter ratio.
