A Cavitation Erosion Model for Ductile Materials [PDF]
, 2001 An analytical model is proposed for the prediction of cavitation erosion of ductile materials. It is based upon a physical analysis of the work-hardening process due to the successive bubble collapses.

Cavitation erosion in liquid nitrogen
Wear, 2018 Abstract Thermodynamic effects in cavitation become significant only when the critical-point temperature is close to the operating temperature of the fluid, as in the case of cryogenic fluids. Therefore, the understanding and the prediction of the cavitation effects in such cases is crucial in many applications - for example the turbopumps for liquid

Effects of plating on cavitation erosion.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1987 to study the cavitation erosion behavior of interface and base metal for platings, magneto-strictive erosion tests were carried out in a 3% NaCl solution using a 0.18% carbon steel specimen plated thinly with zinc, tin, chromium or nickel. When erosion attack extends to the interface between the plating and base metal, chromium or nickel plating which ...

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 ...

Erosion and rolling contact wear mechanisms in silicon nitride hybrid bearings. [PDF]
One remarkable advantage of hybrid bearings over all steel bearings is the elimination of separate oil lubricant system in applications, such as compressors and pumps in refrigeration and air conditioning units.
