Whether it is the propeller of a ship or the dam of a hydropower station, both have suffered serious cavitation damage caused by the collapse of bubbles.

Molecular Dynamics Simulation on Cavitation Bubble Collapse

The experimental apparatus for the cavitation damage is a closed-loop test rig, and the test section is similar to the shape of contraction-divergence of the Venturi tube as shown in Figures 1 and 2.

Study of Cavitation and Cavitation Erosion Quantitative Method Based on Image Processing Technique

Bubbles, the direct product of cavitation, are broken suddenly after moving into the high pressure areas, which will cause cavitation damage such as shortening the ECWP reliability and producing vibration and noise.

Amador et al., [1] stated that the zone near the inception point of air entrainment will be critical in terms of the risk of cavitation damage. They studied characterizing the developing flow region and examined the pressure fluctuation on the steps induced by the skimming flow.

Experimental study of environmental effect of installing deflector on energy dissipation and dynamic pressure fluctuations on stepped spillways

Semicrystalline polymers are known to exhibit cavitation damage when stretched above their glass transition temperature [1, 2], Such a phenomenon has been largely reported until recently for instance in polyethylene (PE) [3-5], polyoxymethylene (POM) [6, 7], polyamide 11 (PA 11) [8], polypropylene (PP) [9, 10] or polyvinylidene fluoride (PVDF) [11-13],
