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.

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 ...

Studies on Cavitation Erosion

Journal of Basic Engineering, 1972
Cavitation damage tests of iron and steel have been carried out using two types of experimental facilities. One is a water tunnel system which presumably simulates the field conditions fairly closely and the other is a magnetostriction vibratory unit commonly used for accelerated cavitation erosion testing of metals.

Accelerated Cavitation Erosion and Sand Erosion

1962
This paper presents comparative scales for the selection of metals based on the ASME cavitation erosion test and the Stauffer sand erosion test, in which hard chromium electroplated on cast steel has been designated with a relative weight loss of 1 in both scales.

Cavitation erosion of materials

International Materials Reviews, 1986
AbstractAfter a brief historical survey of cavitation and its deleterious effects, erosion and material response are considered from the point of view of stress field generation caused by cavitation collapse and the ensuing physical and chemical processes which contribute to erosion damage.

Cavitation erosion of concrete

Hydrotechnical Construction, 1978
1. The choice of components and composition of concrete should be based on consideration of all factors of both the environment and the concrete that can have an effect on its cavitation resistance, including the climatic factor and degree of corrosiveness and erosiveness of the water. 2.

Cavitation Erosion in Hydroturbines

Journal of Hydraulic Engineering, 1989
This paper is based on a field survey of the operational and design characteristics of 729 hydroturbines installed since 1950 having either a capacity in excess of 20 MW or a discharge diameter greater than 3 m. This data base includes 67% of the total U.S. hydropower capacity (40,000 MW).
