Electrical and Thermal Modeling of a Molten Salt Electro-Refiner
Numerical simulation can be advantageously employed to predict the main cell features (e.g., the reaction rate distribution on the electrodes, the cell voltage, or the electrolyte temperature) in order to optimize the design and operational conditions of the process.
In this poster, we describe two complementary computational approaches applied to a molten salt electro-refiner for predicting (1) the current distributions at the surface of the electrodes and (2) the temperature throughout the cell. The electrical model relies on the secondary current theory, i.e. with activation-based overpotentials. The thermal model accounts for the three transport modes (conduction, convection and radiation) of the heat that is generated by the current flow and the overpotentials, both simulated with the electrical model.
