| Abstract Scope |
Ultrasound processing of materials often involves the application of ultrasound of different intensities into a multiphase mixture of liquid and solid phases. There are intensive interactions between the liquid and solid phases as well as the cavitation bubbles due to ultrasound. To understand the transient, multiscale and multiphase interactions fully, we have developed bubble dynamic models based on the Volume of Fluid (VOF) and Continuous Surface Force (CSF) methods. The model is able to simulate bubble oscillation, implosion, and coalescence dynamics under ultrasound. The model has been validated via comprehensive image data collected by ultrafast synchrotron X-ray imaging. Here, we focus on studying bubble interactions with solid phases and the associated stresses due to bubbles oscillation and implosion as well as the effect of multiple bubbles coalescence. The chain effect of multi bubble implosion on the phase exfoliation of 2D materials was reported for the first time. |
