Supersonic needle-jet generation with single cavitation bubbles
, 2021 Collapsing cavitation bubbles produce intense microscopic flows. Here, in an aqueous environment, we seed single laser-induced bubbles (diameter about one millimeter) in proximity to a solid surface, in a regime that has not been well explored before in ...

Investigation of cavitation phenomenon with different fuel temperatures in diesel nozzles
Advances in Mechanical Engineering, 2023 Two-phase cavitating flow in the diesel nozzle has been widely concerned by researchers for a long time. Most of the attention has been paid to irregular geometry-induced cavitation, while the research on string cavitation induced by vortex is relatively

The 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

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

The effect of ultrasound cavitation on endothelial cells
Experimental biology and medicine, 2021 Acoustic cavitation has been widely explored for both diagnostic and therapeutic purposes. Ultrasound-induced cavitation, including inertial cavitation and non-inertial cavitation, can cause microstreaming, microjet, and free radical formation.

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