Determination of resistance to cavitation of pyrophyllite samples

Zaštita Materijala, 2021
The resistance under the action of cavitation of sintered pyrophillite samples was investigated. The initial sample of pyrophillite from the Parsovic-BiH deposit was ground a vibrating mill to a granulation of 20 mm, pressed and sintered at temperatures (

Study of the cavitating instability on a grooved Venturi profile [PDF]

, 2013
Cavitation is a limiting phenomenon in many domains of fluid mechanics. Instabilities of a partial cavity developed on an hydrofoil, a converging-diverging step or in an inter-blade channel in turbomachinery, have already been investigated and described ...

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

International 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.

On the definition of cavitation intensity

Ultrasonics Sonochemistry, 2020
Cavitation intensity has already been used to character the activity or strength of cavitation, and several methods are developed to measure the cavitation intensity. However, the previous definitions of cavitation intensity are often either vague or biased.

Cavitation in soft matter [PDF]

Proceedings of the National Academy of Sciences, 2020
Cavitation is the sudden, unstable expansion of a void or bubble within a liquid or solid subjected to a negative hydrostatic stress. Cavitation rheology is a field emerging from the development of a suite of materials characterization, damage quantification, and therapeutic techniques that exploit the physical principles of cavitation.

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

Numerical Investigation on the Cavitating Flow and the Cavitation-induced Noise in the Pump-jet Propeller [PDF]

Journal of Applied Fluid Mechanics
The noise hazard posed by cavitation in pump-jet propellers is a significant concern during oceanic operations. This study evaluates the cavitation performance and associated noise characteristics of pump-jet propellers in underwater conditions, further ...

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.

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.

Assessment of RANS turbulence models and Zwart cavitation model empirical coefficients for the simulation of unsteady cloud cavitation [PDF]

, 2019
The numerical simulation of unsteady cavitation flows is sensitive to the selected models and associated parameters. Consequently, three Reynolds Average Navier-Stokes (RANS) turbulence models and the Zwart cavitation model were selected to assess their ...
