A Theoretical Research on the Affective Factors of the Transimission of Ultrasonic Used in Descaling

In order to get a good cleaning effect, we can change the location of ultrasonic cleaning device according to the ultrasonic propagation characteristics of ultrasonic. Judge by Doppler shift principle, this article build an equation which depict that ultrasonic disseminate in the mobile liquid. According to the relationship between viscous force and velocity gradient, this article build an equation which depicts that ultrasonic disseminate in the viscous liquid. The equation was facilitated and solved base on the characteristic of axial symmetry model. The results indicated that the velocity of mobile liquid can enhance the sound wave attenuation.The faster liquid flow rate, the higher the degree of attenuation. Liquid viscosity plays an important role in sound wave attenuation. The high frequency of ultrasonic, the more attenuation will produce.
