Caption: Cavitation damage
should be prevented by changing the pumping system characteristics.
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.
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.
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.
The computations of pressure along spillway chute are used to examine the potential for cavitation damage
due to excessive sub atmospheric pressure.
The new ones saw the excellent result obtained by other owners and chose Ecoshield to prevent corrosion and cavitation damage
In addition, improved understanding of this phenomenon is also applicable to the cavitation damage
study of hydraulic machinery operating in high-sediment content environment.
Amador et al.,  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.
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) , polypropylene (PP) [9, 10] or polyvinylidene fluoride (PVDF) [11-13],
The report also said the HP fuel pumps from both engines of the Boeing 777 had "unusual and fresh cavitation damage
to the outlet ports consistent with operation at low inlet pressure".
