Cavitation refers to a distinctive occurrence within liquid flows where there is a phase change process involving the rapid transformation of liquid into vapour in regions of low pressure, followed by collapsing or implosion when pressure rises again. The study of cavitation dates back to the late 19th century. While the term “cavitation” was originally coined by R. E. Froude and first documented by Barnaby and Thornycroft in 1895, the concept had been speculated upon much earlier by L. Euler in his 1754 theory on water turbines. However, the phenomenon of cavitation was initially observed and examined by Barnaby and Parsons in 1893. They identified that the formation of vapour bubbles on propeller blades had led to the failure of the sea trial of the British high-speed warship HMS Daring in 1885. In 1895, Parsons established the first water tunnel dedicated to cavitation research, revealing the connection between cavitation and propeller damage. The theoretical groundwork for cavitation research was laid by Rayleigh in 1917, as he successfully addressed the collapse of an empty cavity within a substantial liquid mass. Since then, numerous research work has been published on cavitating flow.

The book focuses on the fluid dynamics of cavitation with special reference to high power density turbopumps, where it represents the major source of performance and life degradation. While covering the more fundamental aspects of cavitation and the main kinds of cavitating flows, there is focus on the hydrodynamics and instabilities of cavitating turbopumps. The book also illustrates the alternative approaches for modeling and engineering simulation of cavitating flows.

This theses presents the design, development and operations of a Cavitation Susceptibility Meter based on the use of a venturi tube for the measurement of the content of active cavitation nuclei in water samples. The pressure at the venturi throat is determined from the upstream pressure and the local flow velocity without corrections for viscous effects because the flow possesses a laminar potential core in all operational conditions. The detection ov cavitation and the measurement of the flow velocity are carried out optically. The apparatus comprises a Laser Doppler Velocimeter for the measurement of the flow velocity and the detection of cavitation, a custom-made electronic Signal Processor for real time generation and temporary storage of the data and a computerized system for the final acquisition and reduction of the collected data. The results of application of the Cavitation Susceptibility Meter to the measurement of the water quality of the tap water samples are presented. The results of an investigation are presented on the linearized dynamics of two-phase bubbly flows with the inclusion of bubble dynamics effects. Two flow configurations have been studied: the time dependent one-dimensional flow of a spherical bubble cloud subject to harmonic excitation of the far field external pressure and the steady state two-dimensional flow of a bubbly mixture on a slender profile of arbitrary shape.
