Validation of Ultrasound Cavitation at Different Frequency in an Ultrasound Bath using the Aluminium Foil Corrosion Test

Abstract

Ultrasound baths are one of the beneficial applications of ultrasonic cavitation, and they are widely utilized in various industries. The study aims to validate the effects of frequency and number of piezoelectric transducers in an ultrasound bath by measuring cavitation intensity using the aluminium foil corrosion test through the graphical method. The experimental variables include 20 kHz of two piezoelectric transducers, 40 kHz of two piezoelectric transducers, 20 kHz of four piezoelectric transducers, and 40 kHz of four piezoelectric transducers. A standard piece of aluminium foil was placed horizontally in the bath for five minutes. Tests were conducted at various liquid depths, ranging from 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5 litres. The results indicate that the cavitation intensity and the corroded area increased with greater liquid depth. Each configuration demonstrated a high level of significance. The study concludes that the40 kHz of four piezoelectric transducers generates the highest cavitation intensity, resulting in the most intensive corroded area on the aluminium foil.
