Prediction of Cavitation Intensity and Erosion Area in Centrifugal Pump by Using Cavitating Flow Simulation with Bubble Flow Model

Journal of Fluid Science and Technology, 2010
We developed a numerical simulation code and a method of estimation for predicting the cavitation erosion in pumps. Cavitation erosion is closely related to cavitation intensity based on bubble dynamics.

Mesoscale Analysis of Cavitation and Cavitation Erosion [PDF]

, 2020
Cavitation is one of the most common types of damage in hydraulic and hydropower engineering projects. In 1941, the spillway of the Boulder Dam in the U.S. suffered cavitation and developed a deep cavitation pit of 35 m in length, 9.5 m in width, and 13.7 m in depth at the end of its ogee section as a result of the washing away of over 4500 m3 of ...

Numerical Prediction of Cavitation Erosion Risk Based on a New Erosion Indicator

International Journal for Numerical Methods in Fluids
Cavitation erosion would degrade the performance of the fluid machinery. To improve the reliability and prolong the life span of fluid machinery, it is necessary to study the mechanism of cavitation erosion and predict the possibility of erosion.

Cavitation erosion behaviour of MAB-CU4 alloy: influences of cavitation number, attack angle, time, and stand-off distance

Materials Research Express
The present study comprehensively examines the cavitation erosion behaviour of a manganese aluminium bronze alloy (MAB-CU4 alloy) as a function of several parameters (i.e., cavitation angle, cavitation number, time, and stand-off distance), particularly ...
