Available in PDF, EPUB and Kindle. Book excerpt: A rotating foil apparatus was developed and used to study the effect of exposure time, pressure, velocity and size of the foil on intensity of cavitation erosion. Earlier studies with a vibratory apparatus showed that the rate of erosion increases with exposure time, reaches a maximum value and then decreases. These observations are essentially confirmed for the case of erosion on an actual hydrofoil. The maximum rate of erosion is then correlated with the cavitation parameter for two sizes of NACA 16-021 hydrofoil (3 inches and 1 1/2 inches in chord length). The intensity of erosion increases with decreasing cavitation parameter, reaches a peak and then decreases with decreasing cavitation parameter at a given velocity. An approximate analysis was made to explain this result. According to this analysis, the intensity of erosion should vary as the cube of the velocity and should be independent of the size of the foil. However, the experimental results show that the intensity of erosion varies as the sixth power of the velocity and also depends on the size of the foil. An understanding of these two scale effects is essential for a successful model-prototype correlation. (Author).

Book Synopsis Fundamentals of Cavitation by : Jean-Pierre Franc
Download or read book Fundamentals of Cavitation written by Jean-Pierre Franc and published by Springer Science & Business Media. This book was released on 2006-01-22 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Scaling Laws for Cavitation Erosion by : A. Thiruvengadam
Download or read book Scaling Laws for Cavitation Erosion written by A. Thiruvengadam and published by . This book was released on 1971 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the report, six scaling laws are derived and used to investigate the feasibility of modeling cavitation erosion. The velocity scale and size scale are studied with regard to six nondimensional ratios, namely. the erosion number, the relative nuclei size, the Weber number, the cavitation number, the cavitation inception number and the degree of cavitation. These scaling laws indicate that it is possible to model erosion in the laboratory and to predict the prototype performance. In addition, these scaling laws may be used to explain many currently available experimental observations.

Download or read book Advanced Experimental and Numerical Techniques for Cavitation Erosion Prediction written by Ki-Han Kim and published by Springer. This book was released on 2014-07-08 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive treatment of the cavitation erosion phenomenon and state-of-the-art research in the field. It is divided into two parts. Part 1 consists of seven chapters, offering a wide range of computational and experimental approaches to cavitation erosion. It includes a general introduction to cavitation and cavitation erosion a detailed description of facilities and measurement techniques commonly used in cavitation erosion studies, an extensive presentation of various stages of cavitation damage (including incubation and mass loss) and insights into the contribution of computational methods to the analysis of both fluid and material behavior. The proposed approach is based on a detailed description of impact loads generated by collapsing cavitation bubbles and a physical analysis of the material response to these loads. Part 2 is devoted to a selection of nine papers presented at the International Workshop on Advanced Experimental and Numerical Techniques for Cavitation Erosion Prediction (Grenoble, France, 1-2 March 2011) representing the forefront of research on cavitation erosion. Innovative numerical and experimental investigations illustrate the most advanced breakthroughs in cavitation erosion research.

Book Synopsis Hydrodynamics of Pumps by : Christopher E. Brennen
Download or read book Hydrodynamics of Pumps written by Christopher E. Brennen and published by Cambridge University Press. This book was released on 2011-03-28 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrodynamics of Pumps is a reference for pump experts and a textbook for advanced students. It examines the fluid dynamics of liquid turbomachines, particularly pumps, focusing on special problems and design issues associated with the flow of liquid through a rotating machine. There are two characteristics of a liquid that lead to problems and cause a significantly different set of concerns than those in gas turbines. These are the potential for cavitation and the high density of liquids, which enhances the possibility of damaging, unsteady flows and forces. The book begins with an introduction to the subject, including cavitation, unsteady flows and turbomachinery, basic pump design and performance principles. Chapter topics include flow features, cavitation parameters and inception, bubble dynamics, cavitation effects on pump performance, and unsteady flows and vibration in pumps - discussed in the three final chapters. The book is richly illustrated and includes many practical examples.

Book Synopsis Cavitation in Non-Newtonian Fluids by : Emil Brujan
Download or read book Cavitation in Non-Newtonian Fluids written by Emil Brujan and published by Springer Science & Business Media. This book was released on 2010-09-28 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-Newtonian properties on bubble dynamics and cavitation are fundamentally different from those of Newtonian fluids. The most significant effect arises from the dramatic increase in viscosity of polymer solutions in an extensional flow, such as that generated about a spherical bubble during its growth or collapse phase. In addition, many biological fluids, such as blood, synovial fluid, and saliva, have non-Newtonian properties and can display significant viscoelastic behaviour. This monograph elucidates general aspects of bubble dynamics and cavitation in non-Newtonian fluids and applies them to the fields of biomedicine and bioengineering. In addition it presents many examples from the process industries. The field is strongly interdisciplinary and the numerous disciplines involve have and will continue to overlook and reinvent each others’ work. This book helps researchers to think intuitively about the diverse physics of these systems, to attempt to bridge the various communities involved, and to convey the interest, elegance, and variety of physical phenomena that manifest themselves on the micrometer and microsecond scales.

This book was released on 2023-11-06 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
