Cavitation erosion of materials

, 1980
This investigation was undertaken to find the optimum hydraulic fluids and materials for combating cavitation erosion in hydraulic mining machinery operating,on 5:95 oil-in-water emulsions, Controlled cavitation was generated in the laboratory in a vibratory cavitation apparatus employing the stationery specimen system.

Cavitation and Cavitation Erosion

2014
In this chapter, an introduction to cavitation and cavitation erosion is presented. Cavitation involves the development of various types of vapor structures (such as attached cavities, travelling bubbles, vortical cavities, bubble clouds) in liquid flow due to a drop in the local pressure below a critical value usually close to the vapor pressure ...

Numerical Modelling of Cavitation Erosion

Volume 2: Fora, 2008
The goal of the work is to develop an expert system for monitoring and control of cavitation in hydraulic machines and to research the possibility of cavitation erosion prediction using CFD tools only. The geometry in question is a simple single hydrofoil, which is exposed to the developed cavitating flow at different flow conditions.
