The Non-intrusive Detection of Incipient Cavitation in Centrifugal Pumps [PDF]

This thesis investigates methods for the detection of incipient cavitation in centrifugal pumps. The thesis begins by describing the working of the centrifugal pump which makes this type of pump particularly prone to cavitation.

Cavitation induced starvation for piston-ring/liner tribological conjunction. [PDF]

, 2011
The study investigates the mechanism of ring-liner lubrication in the vicinity of the top and bottom dead centres of an internal combustion engine. Predicting lubricant transient behaviour is critical when the inlet reversal leads to thin films and ...

Destruction Mechanism of ZnAl4 as Cast Alloy Subjected to Cavitational Erosion Using Different Laboratory Stands

Archives of Foundry Engineering, 2016
The main reason of a cavitational destruction is the mechanical action of cavitation pulses onto the material’s surface. The course of cavitation destruction process is very complex and depends on the physicochemical and structural features of a material.

The Effect of the Mechanical Properties of Aluminum Alloys on Their Resistance to Cavitation Erosion

Applied Sciences
The degradation of material surface structures caused by cavitation is of a mechanical nature due to cyclic local fatigue loading. Its intensity depends on both the material’s mechanical properties and its surface microstructure.
