Cloud cavitation on an oscillating hydrofoil [PDF]

, 1994
Cloud cavitation, often formed by the breakdown of a sheet or vortex cavity, is believed to be responsible for much of the noise and erosion damage that occurs under cavitating conditions.

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 ...

Cavitation Erosion Modelling – Comparison of Different Driving Pressure Approaches

International Journal of Simulation Modelling, 2023
In this paper we compared different driving pressure approaches to calculate the cavitation potential energy from a source, which is transferred to a surface. The first approach used the reference pressure, the second approach used the pressure calculated at each timestep with no averaging, the third approach used the averaged pressure values from all ...

Wavy‐Interlocked Stretchable Triboelectric Nanogenerators Enhanced by Liquid Metal Microflowers for Self‐Powered Wearable Motion Monitoring

Advanced Science, EarlyView.
Schematic showing a stretchable triboelectric nanogenerator based on interlocked wavy architectures that uses EGaIn microflower‐embedded PVDF‐TrFE and Nylon‐6 nanofiber membranes. The multi‐petaled, electron‐rich EGaIn microflowers enhance interfacial polarization and capacitance, while the interlocked wavy architecture enlarges the effective contact ...

Cavitation erosion incubation period [PDF]

Wear, 1983
Abstract To evaluate the “incubation period” (IP) stage of cavitation erosion, short-duration vibratory horn tests in tap water were made on soft aluminum alloy (aluminum alloy 1100-O) and also on a much more resistant alloy (316 stainless steel). Curves of weight loss versus time, and corresponding scanning electron microscopy photomicrographs taken
