Non-Spherical Cavitation Bubbles: A Review

open access: yesFluids
Cavitation is a phase-change phenomenon from the liquid to the gas phase due to an increased flow velocity. As it causes severe erosion and noise, it is harmful to hydraulic machinery such as pumps, valves, and screw propellers.

Experimental study of laser-induced bubble collapse near a rigid wall based on the double-exposure method [PDF]

open access: yesInternational Journal of Fluid Engineering
Capturing and studying the process of cavitation bubble collapse can help elucidate the mechanism of cavitation erosion. In this paper, a high-spatiotemporal-resolution double-exposure photographic method is used to investigate the collapse of laser ...

Study of cavitation bubble collapse near a rigid boundary with a multi-relaxation-time pseudo-potential lattice Boltzmann method

open access: yesAIP Advances, 2020
Due to the complex phase change and heat transfer processes, the mechanisms of cavitation bubble collapse near a rigid boundary are well recognized to be complicated.

A Note on Partial Cavitation of Flat Plate Hydrofoils [PDF]

open access: yes, 1955
Recently Tulin and Wu have treated the problem of fully developed cavitation on flat plate and cambered foils. In these treatments, the length of the cavity is always greater than the chord of the hydrofoil and the cavity is assumed to start at the ...

Diffuse interface modeling of a radial vapor bubble collapse [PDF]

open access: yes, 2015
A diffuse interface model is exploited to study in details the dynamics of a cavitation vapor bubble, by including phase change, transition to supercritical conditions, shock wave propagation and thermal conduction.

Focused Ultrasound‐Induced Mechanical Ablation Affects the Carbohydrate Metabolism of Residual/Peri‐Focally Localized Glioblastoma Cells

open access: yesInternational Journal of Cancer, EarlyView.
Glioblastoma (GBM) is highly aggressive and therapy‐resistant, warranting exploration of novel treatment strategies, among them mechanical high‐intensity focused ultrasound (mFUS), which holds significant promise for tumor ablation. The present study examined mFUS‐induced changes specifically in carbohydrate metabolism, which affects vulnerability to ...

Comparison of cavitation bubbles evolution in viscous media

open access: yesEPJ Web of Conferences, 2018
There have been tried many types of liquids with different ranges of viscosity values that have been tested to form a single cavitation bubble. The purpose of these experiments was to observe the behaviour of cavitation bubbles in media with different ...

Cavitation scaling experiments with headforms : bubble dynamics [PDF]

open access: yes, 1992
Utilizing some novel instrumentation which allowed detection and location of individual cavitation bubbles in flows around headforms. Ceccio and Brennen (1991 and 1989) recently examined the interaction between individual bubbles and the structure of the

Cavitation inception from bubble nuclei [PDF]

open access: yesInterface Focus, 2015
Abstract The tensile strength of ordinary water such as tap water or seawater is typically well below 1 bar. It is governed by cavitation nuclei in the water, not by the tensile strength of the water itself, which is extremely high. Different models of the nuclei have been suggested over the years, and experimental investigations of ...

Implantable drug delivery system: Frontiers of medicine‐engineering interdisciplinary

open access: yesInterdisciplinary Medicine, EarlyView.
This review systematically summarizes the driving mechanisms of implantable on‐demand drug delivery systems (IDDS), including endogenous, exogenous, and closed‐loop strategies. It highlights the pivotal roles of flexible electronics and miniaturization in enhancing the tissue conformity and spatial adaptability.
