In order to meet the visualization requirements of the cavitation field distribution in the ultrasonic cavitation reactor, a method based on the numerical simulation of the amplitude of sound pressure is proposed. In order to verify that the amplitude of sound pressure plays a decisive role in cavitation effect, the dynamic equation of a single cavitation bubble is established, and the influence law of the amplitude of sound pressure on cavitation motion is analyzed in principle; then, the three-dimensional model of the self-built drum type ultrasonic cavitation reactor is built using the finite element software COMSOL Multiphysics, and the amplitude distribution of the sound pressure at the longitudinal section is obtained when the liquid height was 25 mm, 60 mm and 90 mm. Through the comparison of aluminum foil corrosion experiments, it shows that the numerical simulation method based on the amplitude of sound pressure can accurately characterize the distribution area of ultrasonic cavitation field, which overcomes the disadvantage of time-consuming and labor-consuming in the traditional measurement method of cavitation field distribution, and lays a foundation for the study of the distribution law of ultrasonic cavitation field.
