Effects of an Injection Angle of Water Pipes in an Ultrasonic Cleaning Tank on Particle Disposal Capability

This paper presents simulation of particle dispersion in an ultrasonic cleaning tank.Contaminants removed from work-pieces by means of ultrasonic waves need to be disposed from the tank during the cleaning process. This is achieved by using water injection from horizontal tubes placed at the bottom inside the tank. It is expected that injection angles could affect the performance of particle disposal. The two-phase flow simulation is adopted to predict disposal capability while the computational fluid dynamic is carried out by means of finite volume analysis. Simulation results of particle dispersion in the tank with various injection angles are conducted, displayed, and concluded.
