Evaluation of Cavitation Erosion based on Erosion Particles [PDF]

, 2001
Cavitation erosion mechanisms were studied through the observation of removed particles for annealed S15C (equivalent to AISI 1015) steel and heat-treated S55C (AISI 1055) steels. In the initial and the incubation stages, single impact loads removed many

Cavitation Light Emission and Cavitation Erosion

Journal of The Japan Institute of Marine Engineering, 2008
Cavitation bubbles emit a very weak light due to bubble collapse. It is expected that the light emission may be closely related to cavitation erosion. In order to confirm the relationship between the erosion damage rate and the light intensity, experiments were performed for a water orifice cavitation flow. A circular pipe was used and water-cavitation

Dynamics of the Cloud Cavitation and Cavitation Erosion.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1999
It is well known that a cloud cavitation is one of the most destructive forms of cavitation. The set of equations for the motion of a spherical bubble cloud is formulated. Behavior of bubble clouds are simulated numerically when the surrounding pressure is decreased from 50 kPa to a 10 kPa and then increased to 50 kPa.

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 ...

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.

Comparison of cavitation erosion behaviors between the as-cast and friction stir processed Ni–Al bronze in distilled water and artificial seawater

Journal of Materials Research and Technology, 2021
In this investigation, the friction stir processing (FSP) method was utilized to improve the properties of the surface of the as-cast nickel aluminum bronze (NAB) alloy in two different processing parameters.

Prediction of Cavitation Erosion

Journal of the Society of Naval Architects of Japan, 1995
The objective of this study is to develop a procedure of predicting the cavitation erosion intensity. To this end, it is necessary to estimate impulsive forces caused by collapse of cavity bubbles. In the first report the authors measured cumulative events of impulsive forces by collapse of cavity bubbles on a two-dimensional foil with a piezoelectric ...
