Buffer chemical polishing is a cheap, simple and effective processing technique for single grain high gradient and polycrystalline lower gradient cavities.
This paper describes the thermal-fluid finite element model adopted to simulate the process, the experimental flow visualization tests performed to verify the simulation and a novel device fabricated to solve the problem.
