Cavitation in a propeller causes erosion, accelerating corrosion, and tearing off blades severe cases. Despite the maintenance requirements caused by cavitation, few studies have investigated cavitation resistance of small ship propellers. Therefore, this study, these characteristics were through demonstration test coastal waters South Korea. erosion analyzed according to low- high-rotational s...

Cavitation has been proven to cause damage hydraulic structures. In recent times, aeration receiving increasing attention as a suitable method for preventing or reducing the erosion effects of cavitation. this study, an orifice with micrometer-sized diameter was designed introducing air bubbles in water examine reduction caused by cavitation ultrasonic environments. The experimental results sho...
