Computational Modelling of Fluid Dynamics in Electropolishing of Radiofrequency Accelerating Cavities

The work hereafter investigates into the use of COMSOL Multiphysics® to simulate the electropolishing process performed on radiofrequency accelerating cavities in order to improve their inner metal surface finishing. The physics studied in COMSOL Multiphysics® is the fluid dynamics of the process, and the use of exported velocity data is made to transpose into current density to determine the effectiveness of the existing electropolishing process currently undertaken at CERN.
