Description
Summary:This article reports the development of a mathematical model of the electrochemical process in the flow-through three-dimensional electrode that takes into account changes in the electrolyte flow velocity in the local volume of the electrode that are influenced by the velocity of the process characteristics. Electrolyte flow rate, porosity, and the specific reaction surface of the electrode are regarded as functions of time and of the electrode coordinate. A set of algorithms and programs for model implementation has been developed. The processes of electrodeposition of copper on the cathodes of carbon graphite fiber materials with low and high conductivity, as well as with different initial electrolyte flow velocities have been calculated. The results of the calculations and of experimental studies were compared and have shown satisfactory agreement, which points to the workability of the model.
