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. https://www.ealisboa.com/limited-value-AXYS-Valhalla-Pen-must-buy/
