Simulation of ultrasonic cleaning and ways to improve the efficiency

Improved Design of Ultrasonic Cleaning Tank Using Harmonic Response Analysis in ANSYS

“…We would therefore like to use the acoustic pressure from the simulation in our previous work [10] as reference. The results from reference [10] were confirmed the accuracy by comparing with foil corrosion test.…”

“…We would therefore like to use the acoustic pressure from the simulation in our previous work [10] as reference. The results from reference [10] were confirmed the accuracy by comparing with foil corrosion test. Since our work in this article uses similar methodology, u/s tank model and operating conditions to the work in reference [10], this makes us confident that the methodology used, and simulation results obtained in this research are credible.…”

“…The u/s tank model and other environmental conditions did not include. Recently, to find ways for improving the performance of ultrasonic cleaning in a simple tank, we simulated the acoustic pressure distribution using the Harmonic Response Analysis in ANSYS based on actual conditions from the factory [10]. The results of simulation were confirmed by the experiment of foil corrosion test.…”

“…Thus, we needed to create a highly detailed mesh. The mesh in each model must have at least 6-12 elements in 1 wave length to ensure that the pattern from our simulation is realistic [10,12]. The mesh model for the actual and improved design of u/s tanks are shown in figure 4 and 5.…”

“…The position that provided the highest cleaning efficiency was at the middle of the tank. This article is an extension of the research in references [9][10]. We will simulate the acoustic pressure pattern in the u/s tank by using PZT4 and PZT8 as transducers based on actual operating conditions of the factory to compare the cleaning performance.…”
