Investigates cavitation dynamics in elliptical hydrofoils, suggesting implications for fluid dynamics.

The research aims to understand the unsteady oscillation of sheet and tip vortex cavitation around a hydrofoil.
Utilized high-speed imaging and time-resolved tomographic particle image velocimetry for analysis.
Conducted synchronized measurements of the radiated noise during cavitation phenomena.
Analyzed flow organization and turbulent kinetic energy production across oscillation phases.
Identified three oscillation phases with significant growth and collapse of cavitation structures.
Observed that the tip vortex experiences breakdown and violent fluctuations due to vortex interactions.
Found a strong correlation between sound pressure variation and cavity morphology throughout the oscillation cycle.

Wang et al. (2026) studied this question.
