Statistical modeling of cavitation inception

2022
Cavitation is the phenomenon of bubbles growing when the liquid pressure drops below vapor pressure. Cavitation is mostly undesirable and fluid engineering systems are often designed to avoid it, so proper prediction of the cavitation inception point is important.

The crevice model of cavitation inception

The Journal of the Acoustical Society of America, 2021
In Robert Apfel’s Ph.D. dissertation and in subsequent published articles, he demonstrated that if one chose a volume small enough—say a microdroplet—cavitation could not be generated even at elevated temperatures. He expanded the work of Harvey (J. Cell. Comp. Physiol. 24, 23 (1944) who proposed the crevice model of cavitation nucleation. Recently, Lu

Viscous Effects in the Inception of Cavitation

Journal of Fluids Engineering, 1981
The inception of cavitation in the steady flow of liquids around bodies is seen to depend upon the real fluid flow around the bodies as well as the supply of nucleating cavitation sources—or nuclei—within the fluid. A primary distinction is made between bodies having a laminar separation or not having a laminar separation.

Reconsideration of Cavitation Inception Theory

Volume 1: Symposia, Parts A and B, 2007
The nonlinear dynamics of a spherical gas bubble in a liquid water is reconsidered on the basis of the Rayleigh-Plesset equation with particularly emphasis on the unstable behavior with respect to infinitesimal perturbations. The evolution of bubble radius after the discontinuous change of ambient pressure is theoretically analyzed, and the classical ...

Mechanism of the Inception of Hydraulic Cavitation

Journal of Applied Physics, 1966
For the purpose of clarifying the physical nature of the inception of hydraulic cavitation, distilled water saturated with air at an atmospheric pressure was injected as a free jet through small glass nozzles into the same kind of liquid under various states of thermodynamic meta-stability.

Similarity problem of inceptive cavitation

Applied Mathematics and Mechanics, 1985
In a preceding article [the author, ibid. 4, 825-831 (1983; Zbl 0557.76118)], the relation between thermodynamics condition and inceptive cavitation stage has been discussed. In this paper, we try to introduce the volume function of inceptive cavitation bubbles, \(z_ 0(r)\), instead of the energy equation used in the preceding article, for discussing ...

Cavitation Inception on Rotating Rods

SNAME 22nd American Towing Tank Conference, 1989
In order to investigate the character of cavitation inception from rotating rods, a series of experiments were performed in the 5000x450x450 mm test section of the University of Tokyo Propeller Cavitation Tunnel. This paper presents a summary of the experimental design, a comparison of the cavitation patterns for stationary and rotating rods, and the ...

Bubble Dynamics and Cavitation Inception in Cavitation Susceptibility Meters

Journal of Fluids Engineering, 1986
To improve the understanding of the scaling effects of nuclei on cavitation inception, bubble dynamics, multibubble interaction effects, and bubble-mean flow interaction in a venturi Cavitation Susceptibility Meter are considered theoretically. The results are compared with classical bubble static equilibrium predictions.

Cavitation inception following shock wave passage

Physics of Fluids, 2002
Cavitation bubble nucleation following the passage of an extracorporeal shock wave lithotripter pulse is investigated experimentally and numerically. In the experiments two configurations are considered: Free passage of the shock wave, and reflection of the shock wave from a rigid reflector.

Review—Mechanisms of Cavitation Inception

Journal of Fluids Engineering, 1991
A review is made of progress in research during the period 1979–1989 on the fundamental physical mechanisms of hydrodynamic cavitation inception. During that decade identification of the physical phenomena has been made, and techniques have been developed to reproduce on laboratory scale selected forms of full scale cavitation inception.
