Bubble Size Distribution at Early Stage of Hydrodynamic Cloud Cavitation
Social Science Research Network, 2023The bubble size distribution (BSD) in hydrodynamic cloud cavitation is poorly understood, in spite of its importance in cavitation erosion and noise. Challenges arise owing to the heterogeneous turbulent flows and high void fraction in the cavitation ...

Mechanistic and synergistic aspects of ultrasonics and hydrodynamic cavitation for food processing
Critical reviews in food science and nutrition, 2023Compared with traditional methods, cavitation-based processing technology has received extensive attention for its low energy consumption and high processing efficiency. The cavitation phenomenon releases high energy due to the generation and collapse of

The Physics of Fluids, 2022
Cavitation as a form of unsteady flow within centrifugal pumps can cause the reduced performance of pumps, disordered internal flow regimes and flow loss. The present criterion used for determining the occurrence of cavitation is a 3% head drop. However,

Stratification effect of air bubble on the shock wave from the collapse of cavitation bubble
Journal of Fluid Mechanics, 2021This paper presents an experimental study on the mechanism of interaction between a cavitation bubble and an air bubble. The cavitation bubble was generated by means of the low-voltage discharge method, and the combination of high-speed photography and a
