As an experimental quantitative method to assess erosion risk, the acoustic emission (AE) technique has been employed, for example, by Lloyds Register for more than a decade now to complement their borescopic cavitation observation at the ship scale. Boorsma and Fitzsimmons (2009) reported (see Fig. 1,) its correlation with borescope observed cavitation events appeared very positive and the loc...

-) carbon. A cavitating water jet method was used to examine weight loss versus time as compared to other engineering materials. An ultrasonic horn method was used to describe cavitation erosion morphology of pyrolytic carbon surfaces. The cavitation behavior of pyrolytic carbon by both methods. was highly variable. Cavitation resistance in the water jet model was initially high, but weight los...

Axial-flow pumps, in addition to providing high anti-cavitation properties, must have anti-erosion properties ensure the required lifetime of pump. Erosion damage surfaces occurs when net positive suction head (NPSH) significantly exceeds its critical value. The object study this article is axial-flow pump with a specific speed 600 two alternatives: № 1 and 2. By analysis flow impeller blade sy...

A general methodology is presented for in situ detection of cavitation impact phenomena on structures based on inverse analysis of luminescent emissions resulting from the collapsing of bubbles onto surfaces. Following an inverse-analysis approach, luminescent emission signatures are correlated with the general structure of asymmetric bubble collapse onto a surface. This method suggests applica...
