Abstract:
Formulas for researching acoustical nonlinear phenomena in the sonochemical reactor are derived by using the acoustic pressure of fundamental frequency and second-order resonant frequency, and the nonlinear parameters of acoustic field with variable powers are obtained by this method. The results show that the nonlinear phenomena is obvious, and under the condition of lower power the results are very close to the standard values. Moreover, the acoustic cavitation increases with the power, which cause the increase of nonlinear parameters.
