Abstract
In the present work, the effect of different parameters such as the frequency of irradiation, gas species in a bubble and its cavitation intensity (the key factor affecting the advanced oxidative process) have been studied with numerical solutions. Simulations of cavitation bubble dynamics have been made for harmonic and ultra-harmonic coupling of two ultrasound waves within the frequency range of 20kHz-200kHz with the interval of 20kHz. The results show that the cavitation intensity reduces gradually with the increase of frequency, the peak temperature reached in a cavitation bubble at transient collapse is influenced by the gas species, and in a dual-frequency ultrasonic field, the cavitational activity reaches to its maximum when the two frequency have the same value of 20kHz.
