Cavitation And Associated Phenomena

Cavitation is a dangerous process which destroys objects in a fluid. Scientific description of this multifaceted phenomenon is based on almost every area of physics, and many interesting effects are connected with cavitation. The most intriguing of them is sonoluminescence – the light emitted from a cavitating fluid. This book presents a full-scale description of cavitation: from the basic thermodynamic principles to special phenomena associated with this complex process, from the dynamics of a single gas cavity to the catastrophic macroscopic manifestations, from the domestic observations to the nuances of X-ray spectroscopic research.

Cavitation and Bubble Dynamics deals with fundamental physical processes of bubble dynamics and cavitation for graduate students and researchers.

Cavitation and Bubble Dynamics: Fundamentals and Applications examines the latest advances in the field of cavitation and multiphase flows, including associated effects such as material erosion and spray instabilities. This book tackles the challenges of cavitation hindrance in the industrial world, while also drawing on interdisciplinary research to inform academic audiences on the latest advances in the fundamentals. Contributions to the book come from a wide range of specialists in areas including fuel systems, hydropower, marine engineering, multiphase flows and computational fluid mechanics, allowing readers to discover novel interdisciplinary experimentation techniques and research results. This book will be an essential tool for industry professionals and researchers working on applications where cavitation hindrance affects reliability, noise, and vibrations. Covers a wide range of cavitation and bubble dynamics phenomena, including shock wave emission, jetting, and luminescence Provides the latest advice about applications including cavitation tunnels, cavitation testing, flow designs to avoid cavitation in pumps and other hydromachinery, and flow lines Describes novel experimental techniques, such as x-ray imaging and new computational techniques

This book treats cavitation, which is a unique phenomenon in the field of hyd- dynamics, although it can occur in any hydraulic machinery such as pumps, propellers, artificial hearts, and so forth. Cavitation is generated not only in water, but also in any kind of fluid, such as liquid hydrogen. The generation of cavitation can cause severe damage in hydraulic machinery. Therefore, the prevention of cavitation is an important concern for designers of hydraulic machinery. On the contrary, there is great potential to utilize cavitation in various important applications, such as environmental protection. There have been several books published on cavitation, including one by the same authors. This book differs from those previous ones, in that it is both more physical and more theoretical. Any theoretical explanation of the cavitation phenomenon is rather difficult, but the authors have succeeded in explaining it very well, and a reader can follow the equations easily. It is an advantage in reading this book to have some understanding of the physics of cavitation. Therefore, this book is not an introductory text, but a book for more advanced study. However, this does not mean that this book is too difficult for a beginner, because it explains the cavitation phenomenon using many figures. Therefore, even a beginner on cavitation can read and can understand what cavitation is. If the student studies through this book (with patience), he or she can become an expert on the physics of cavitation.

First published by McGraw-Hill in 1989, this book provides a unified treatment of cavitation, a phenomenon which extends across the boundaries of many fields. The approach is wide-ranging and the aim is to give due consideration to the many aspects of cavitation in proportion to their importance. Particular attention is paid to the diverse situations in which cavitation occurs and to its practical applications.

It signifies that the field has come of age. For those without previous knowledge of this many-faceted subject, the book provides an opportunity to become well acquainted.”Here Dr Young has recognized, and met, the need for a single-authored volume which brings together material from many technical reports, book chapters, student theses and countless journal publications. The material includes basic hydrodynamical and acoustical theory, as well as experimental findings in physics, chemistry, and biology laboratories. Cavitation-related phenomena covered include such diverse examples as erosion of ship propellers, ultrasonic cleaning, detection of high energy particles, fragmentation of biological cells and sonoluminescence.”Obviously, one's education is not complete without an understanding of the possibilities offered by cavitation in its various forms. Dr Young's carefully constructed and wide-ranging book provides readers an opportunity to become informed on this matter, whether in depth, or in breadth.”Professor Wesley L Nyborg University of Vermont
