Research news on Cavitation

Cavitation as a research area investigates the nucleation, growth, dynamics, and collapse of vapor or gas bubbles in liquids subjected to rapid pressure changes, with emphasis on the associated fluid mechanics, thermodynamics, and multiphase flow phenomena. It encompasses experimental, theoretical, and computational studies of bubble inception thresholds, shock-wave emission, and microjet formation, as well as their impacts on erosion, noise, and performance in hydraulic machinery, marine propellers, biomedical ultrasound, and microfluidic systems. Research also addresses cavitation control, damage mitigation, and exploitation of cavitation-induced extreme conditions for applications such as sonochemistry, surface cleaning, and targeted drug delivery.
