Cavitation [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1955
Cavitation is defined as the formation of bubbles in a liquid due to under-pressure applied either once, or periodically by a sound wave. As in boiling, cavitation needs nuclei. There are two problems: What are the nuclei, and how does the bubble behave once formed? Treating the second question first, one must distinguish gas-filled bubbles, found only

Influence of inlet pressure on cavitation characteristics in regulating valve

open access: yesEngineering Applications of Computational Fluid Mechanics, 2020
The cavitation development process in regulating valve under different inlet pressures is investigated experimentally and numerically in our paper. The influence of inlet pressure Pin on cavitation location, shape, area and intensity is studied in axial ...

Viscous Effects in the Inception of Cavitation on Axisymmetric Bodies [PDF]

open access: yes, 1973
Cavitation inception and development on two axisymmetric bodies was studied with the aid of a Schlieren flow visualization method developed for that purpose. Both bodies were found to exhibit a laminar boundary layer separation; cavitation inception was

Characterization of cavitation under ultrasonic horn tip – Proposition of an acoustic cavitation parameter

open access: yesUltrasonics Sonochemistry, 2022
Acoustic cavitation, generated by a piezo-driven transducer, is a commonly used technique in a variety of processes, from homogenization, emulsification, and intensification of chemical reactions to surface cleaning and wastewater treatment.

Research on Cavitation Wake Vortex Structures Near the Impeller Tip of a Water-Jet Pump

open access: yesEnergies, 2023
Cavitation can cause noise in the water-jet pump. If cavitation occurs in the water-jet pump, the hydraulic components in the pump are prone to erosion. The surface erosion reduces energy delivery efficiency and increases maintenance costs.

Relationships between hydraulic traits and habitat preference for six Acer species occurring in the French Alps [PDF]

open access: yes, 2004
Xylem hydraulic properties and vulnerability to cavitation were studied in six Acer species which occur, in the French Alps, along a soil moisture gradient from the moist valleys to the drier mountain stands.

Overlapping Receptor-Based Pathogenic Cascades in Degenerative Disease: Implications Ranging from Tumor Targeting to Aging and Dementia Therapeutics

open access: yesInternational Journal of Translational Medicine
Previous research has already shown that apolipoprotein (apo)A-I is adsorbed from the bloodstream onto the surface of certain colloidal lipid particles after the intravenous injection of such colloidal nanocarriers.

Numerical simulation of three-phase flow in an external gear pump using immersed boundary approach [PDF]

open access: yes, 2019
This paper presents a three-phase fully compressible model applied along with an immersed boundary model for predicting cavitation occurring in a two dimensional gear pump in the presence of non-condensable gas (NCG).
