On the Mechanism of Cavitation Damage [PDF]

open access: greenJournal of Fluids Engineering, 1955
Abstract A new method for producing cavitation damage in the laboratory is described in which the test specimen has no mechanical accelerations applied to it in contrast with the conventional magnetostriction device. Alternating pressures are generated in the water over the specimen by exciting a resonance in the “water cavity.” By this ...

Recent Investigations of the Mechanics of Cavitation and Cavitation Damage [PDF]

open access: greenJournal of Fluids Engineering, 1955
Abstract This paper describes water-tunnel investigations into the mechanics of “fixed”-type cavitation and into the probable mechanism through which this type causes material damage. High-speed motion pictures were used to study the cavity mechanics, and indications of the damage pattern were obtained by measuring the pitting rate on ...

Interfacial cavitation

open access: yesPNAS Nexus, 2022
AbstractCavitation has long been recognized as a crucial predictor, or precursor, to the ultimate failure of various materials, ranging from ductile metals to soft and biological materials. Traditionally, cavitation in solids is defined as an unstable expansion of a void or a defect within a material.

BIOBASED NANOEMULSION FOR BLOCKING COVID-19 FROM ACCELERATING ALZHEIMER'S DISEASE

open access: yesJuvenis Scientia, 2021
An effective therapeutic strategy to delay dementia could be based upon nanotargeting drug(s), using lipid nanocarriers (i.e., biobased nanoemulsion technology), toward a major serum amyloid A (SAA) receptor responsible for certain proinflammatory, SAA ...

Multidimensional Vibro-Acoustical Diagnostics of Cavitation: Theory and Illustration on a Kaplan Turbine

open access: yesFluids, 2022
Korto’s multidimensional method for vibro-acoustical diagnostics and monitoring of turbine cavitation is based on a high number of spatially distributed sensors and the signal and data processing that systematically utilises three data dimensions ...

Characterising the cavitation activity generated by an ultrasonic horn at varying tip-vibration amplitudes

open access: yesUltrasonics Sonochemistry, 2021
Dual-perspective high-speed imaging and acoustic detection is used to characterise cavitation activity at the tip of a commercial 20 kHz (f0) ultrasonic horn, over 2 s sonications across the range of input powers available (20 – 100%). Imaging at 1 × 105
