Marine Propeller Cavitation: When Hydrodynamics Meets Its Limits Cavitation occurs when local pressure in a fluid drops below the vapour pressure, causing liquid water to vapourise and form bubbles that collapse violently when pressure recovers. In the video shown here, this phenomenon is clearly visible under experimental conditions: tip vortices generated at the blade edges create low-pressure cores where cavitation develops. #Cavitation #MarineEngineering #Propellers #Hydrodynamics #Multiphys
