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 (

The Evolution of Cavitation Events with Speed and Scale of the Flow [PDF]

, 1999
This paper focuses on the different forms that individual cavitating events may take when the cavitation number is below the inception value (but not so low as to produce only attached cavities) and individual nuclei trigger individual cavitation events.

Experimental and Numerical Investigation of Tip Leakage Vortex Cavitation in Water-jet Pump [PDF]

Journal of Applied Fluid Mechanics
During the operation of a water-jet pump, cavitation generates noise and vibration, causes surface erosion of the hydraulic components, and reduces the performance of the pump.

Oil Cavitation Morphology Analysis of Textured Cylindrical Rotating Friction Pair on Circular-Disk End Faces

Machines, 2022
Cavitation is a destructive hydraulic phenomenon; it causes damage to small hydraulic machinery and large water-conservancy projects, and cavitation and cavitation corrosion problems are long-standing problems for hydraulic machinery experts.

Research on the Cavitation Flow Characteristics and Transport Mechanism of Rotating Cascades [PDF]

Journal of Applied Fluid Mechanics
In this study, a numerical simulation combining the Detached Eddy Simulation (DES) model with the Zwart Gerber Belamari (Z-G-B) cavitation model is used, along with a visualization experiment, to analyze cavitation flow within a rotating cascade.

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 ...
