Recent Observations on Cavitation and Cavitation Noise
This paper is primarily concerned with the acoustics of traveling bubble cavitation around foils or headforms. We begin with observations of individual bubbles and the acoustic signals they emit, our purpose being to identify areas of research which would enhance our tlriderstaridirig of the history of individual bubbles. Then we present some riumerical integrations of the Rayleigh/Plesset equa...
متن کاملScaling of Cavitation Erosion Progression with Cavitation Intensity and Cavitation Source
A simple mathematical expression is presented to describe cavitation mean depth of erosion versus time for cavitating jets and ultrasonic cavitation. Following normalization with a characteristic time, t*, which occurs at 75% of the time of maximum rate of erosion, and a corresponding material characteristic mean erosion depth, h*, the normalized erosion depth is related to the normalized time ...
متن کاملBackflow Vortex Cavitation and Its Effects on Cavitation Instabilities
Cavitation instabilities in turbo-machinery such as cavitation surge and rotating cavitation are usually explained by the quasi-steady characteristics of cavitation, mass flow gain factor and cavitation compliance. However, there are certain cases when it is required to take account of unsteady characteristics. As an example of such cases, cavitation surge in industrial centrifugal pump caused ...
متن کاملThrombus rupture via cavitation.
Aneurysm growth is accompanied by formation of intraluminal thrombus. The onset of thrombus rupture via unstable void growth is studied in the present note. The experimentally calibrated constitutive model of thrombus developed by Wang et al. (2001) is enhanced with a failure description and used for analysis of cavitation. It is found that unstable cavity growth can start at hydrostatic tensio...
متن کاملCavitation in medicine.
We generally think of bubbles as benign and harmless and yet they can manifest the most remarkable range of physical effects. Some of those effects are the stuff of our everyday experience as in the tinkling of a brook or the sounds of breaking waves at the beach. But even these mundane effects are examples of the ability of bubbles to gather, focus and radiate energy (acoustic energy in the ab...
