The UDF program is written to simulate the cavitation characteristics of polishing media generated by ultrasonic vibration in the mold cavity based on CFD. The simulation results reveal the motion state of polishing media in the mold cavity. On the foundation of detailed study, the optimum combination range of simulation process parameter settings are obtained to play a guiding role for the surface ultrasonic polishing design and development, involving periodic regularity of absolute pressure and vapor fraction, the nonlinear effects of under-relaxation factors to simulation results.
