| Abstract Scope |
Oscillating cavitation bubbles in liquid are predominantly caused by viscosity and the properties of the liquid-bubble interface. Bubble implosion produces localized shock waves that have been proven useful in various processes, especially with ultrasound. However, there has been limited research on the bubble dynamics of highly viscous fluid due to inadequate imaging techniques that can penetrate the transparent ‘thick’ liquid with high spatio-temporal resolution. Here, we report our very recent research on using the MHz X-ray Microscopy available at the SPB/SFX beamline of the European X-ray Free Electron Laser (EuXFEL) to observe in situ the nucleation and growth dynamics of ultrasonic cavitation bubble in Silicone oils (50 to 500 cSt). The result shows, for the first time, the dramatic difference in bubble nucleation and implosion in silicone oils compared to water. These new key findings are crucial in developing ultrasound-enabled 2D materials exfoliation technologies and novel composite manufacturing technologies. |
