Simulation and Mechanism Analysis of Electrochemistry of the Vanadium Redox Couples By a Rotating Disk Electrode
A mathematical mechanism model has been developed based on the physical phenomenon and equations of diffusion, convection, electro-migration, and electrochemical reaction dynamic. The effect of rotating rate on the performance of vanadium couples is simulated, analyzed and comprised with the experimental data. The distributions of velocity, concentration, potential, and current have been provided while the traditional experimental methods could not been done. The simulation technique not only can provides more electrochemical information, but also gives a better understanding of the electrochemical process for the teaching and research.
