Experimental research on the effect of air bubble properties on aluminum cavitation erosion

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 showed that is significantly reduced low concentration, which also reduces structural due At certain concentration level, material do not change when conditions are altered, and wall surfaces protected corrosion reduction; bubble frequency influences erosion, high resulting more conducive environment minimizing damage. influence under same different sizes analyzed. analysis indicated combination satisfies requirements smaller size highly advantageous achieving effect at concentration. Therefore, can be effectively achieved through bubble, and, conservancy projects, it beneficial designing analyzing methods reduce aeration.
