Experimental investigation on cavitating and self-sustained oscillating flow in a horizontal axisymmetric cavity [PDF]

International Journal of Fluid Engineering
An experimental study is performed to reveal the flow phenomena and the oscillation characteristics of water jet flow through a horizontal axisymmetric cavity. The test conditions include different Reynolds numbers and various cavity lengths.

Cavitation Nuclei Population and Event Rates [PDF]

, 1998
To model the processes of cavitation inception, noise and damage, it is necessary to generate a model of the cavitation event rate which can then be coupled with the consequences of the individual events to produce a complete synthesis of the phenomenon.

Jet Flow Field Analysis of Convergent‐Divergent Nozzle for Hydraulic Perforation for Natural Gas Hydrates

Energy Science &Engineering, EarlyView.
Combining the nozzle structure and wellbore size of the second natural gas hydrate trial production, the CFD is employed to analyze the internal and external flow fields of convergent–divergent cavitation nozzle. Analyzing the influence of various structural parameters of the nozzle on its jet performance, and the nozzle configuration with optimal jet ...

Nonthermal Food Processing Technologies: A Comprehensive Review

Future Postharvest and Food, EarlyView.
The graphical abstract illustrates the shift from traditional thermal food preservation methods to advanced nonthermal technologies. Traditional methods, represented by heating, often compromise the nutritional and sensory quality of foods. In contrast, nonthermal approaches such as high‐pressure processing (HPP), pulsed electric field (PEF ...

Controlled Cavitation in Microfluidic Systems [PDF]

, 2007
We report on cavitation in confined microscopic environments which are commonly called microfluidic or lab-on-a-chip systems. The cavitation bubble is created by focusing a pulsed laser into these structures filled with a light-absorbing liquid.
