Study on cavitation number and cavitating flow characteristics in a narrow rectangular Venturi tube

Physics of Fluids
This study investigates the applicability of different cavitation number definitions and the influence of Venturi geometry on cavitating flow dynamics within a narrow rectangular Venturi tube. Experiments were conducted in a closed-loop water tunnel using high-speed imaging and grayscale-based image processing to characterize cavity morphology and ...

Effect of Cavitation Number on the Improvement of Fatigue Strength of Carburized Steel Using Cavitation Shotless Peening

Key Engineering Materials, 2004
Peening can be used to produce a layer of compressive residual stress at the surface of components which are subject to fatigue or stress corrosion, thereby retarding crack initiation and/or impeding the development of new cracks and hence improving their fatigue life.

Thermodynamic effects on cavitation dynamics and modal characteristics around a hydrofoil at different cavitation numbers

Ocean Engineering
Thermodynamic effects significantly alter cavitation behavior in marine systems employing thermosensitive fluids, yet their influence on flow modal characteristics remains poorly understood. This study investigates cavitation dynamics around a NACA0015 hydrofoil using fluoroketone across cavitation numbers σ = 0.7, 1.1, and 1.5, employing Proper ...

Computation of Cavitation Inception Number for Surface Irregularities

Volume 1: Fora, Parts A, B, C, and D, 2003
Computation of cavitation inception number for isolated surface irregularities is performed with the assumption that cavitation bubbles appear in vortices located within viscous separation zones behind these irregularities. The numerical analysis consists of four parts.

The issue of Strouhal number definition in cavitating flow:

2009
In the past years the Strouhal number has been used to define the nature of cavitation cloud shedding in many studies. In particular, it was adopted as an indicator of a simulation agreement to the experiment. The problem is that there are many interpretations of the parameters that are included in its definition, which leads to a confusion and, as ...
