Dynamics Modeling Of Cavitation Bubble In The

t can particularly generate abundant cavitation bubbles in the processing of the power ultrasonic honing. The dynamics of cavitation bubbles in the grinding area are very vital to study the machining mechanism and the cutting chatter of power ultrasonic honing. Based on the Rayleigh-Plesset equation, a new dynamics model of cavitation bubble is established, considering the velocity of .

Cavitation Bubble Dynamics Induced By

During ultrasonic vibration honing UVH, a thin hydrodynamic oil film formed can seriously affect the cavitation effect in the grinding fluid, but the mechanism is still unclear now. Based on the hydrodynamics theory, a revised cavitation bubble model with oil film pressure is developed, and it has been calculated by the four-order Runge .

Ultrasonic Cavitations And Precision Cleaning

The waves interact with liquid media to generate cavitation implosions. High intensity ultrasonic waves create micro vapor vacuum bubbles in the liquid medium, which grow to maximum sizes proportional to the applied ultrasonic frequency and then implode, releasing their energies the higher the frequency, the smaller the cavitation size.
