Download or read book The Acoustic Bubble written by T Leighton and published by Academic Press. This book was released on 2012-12-02 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Acoustic Bubble describes the interaction of acoustic fields with bubbles in liquid. The book consists of five chapters. Chapter 1 provides a basic introduction to acoustics, including some of the more esoteric phenomena that can be seen when high-frequency high-intensity underwater sound is employed. Chapter 2 discusses the nucleation of cavitation and basic fluid dynamics, while Chapter 3 draws together the acoustics and bubble dynamics to discuss the free oscillation of a bubble and acoustic emissions from such activity. The acoustic probes that are often applied to study the behavior of a bubble when an externally-applied acoustic field drives it into oscillation is deliberated in Chapter 4. The last chapter outlines a variety of effects associated with acoustically-induced bubble activity. The bubble detection, sonoluminescence, sonochemistry, and pulse enhancement are also covered. This publication is a good reference for physics and engineering students and researchers intending to acquire knowledge of the acoustic interactions of acoustic fields with bubbles.
Download or read book Acoustic Cavitation and Bubble Dynamics written by Kyuichi Yasui and published by Springer. This book was released on 2017-10-26 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: This brief explains in detail fundamental concepts in acoustic cavitation and bubble dynamics, and describes derivations of the fundamental equations of bubble dynamics in order to support those readers just beginning research in this field. Further, it provides an in-depth understanding of the physical basis of the phenomena. With regard to sonochemistry, the brief presents the results of numerical simulations of chemical reactions inside a bubble under ultrasound, especially for a single-bubble system and including unsolved problems. Written so as to be accessible both with and without prior knowledge of fundamental fluid dynamics, the brief offers a valuable resource for students and researchers alike, especially those who are unfamiliar with this field. A grasp of fundamental undergraduate mathematics such as partial derivative and fundamental integration is advantageous; however, even without any background in mathematics, readers can skip the equations and still understand the fundamental physics of the phenomena using the book’s wealth of illustrations and figures. As such, it is also suitable as an introduction to the field.
Download or read book An Experimental Investigation of Acoustic Cavitation as a Fragmentation Mechanism of Molten Tin Droplets in Water written by Trond Arnold Bjørnard and published by . This book was released on 1974 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of experiments were performed where single molten tin droplets of known size, shape and temperature were dropped from a low height into a pool of distilled water. The pressure waves emanating from the hot droplets were recorded by a transducer in the coolant for varying initial droplet and pool temperatures. The results obtained show well defined patterns of pressure frequency and magnitude behavior. Application of the results to the acoustic cavitation theory of fragmentation shows that the pressure excursions within the molten tin are considerably less severe than was predicted. The likelihood that acoustic cavitation caused the observed fragmentation is therefore considerably diminished. Further, the results strongly suggest that spontaneous nucleation of the coolant did not cause the observed fragmentation, while it appears that another mechanism linked to the observed dwell time behavior was responsible. Further theoretical and experimental work is required to establish the nature of this mechanism.

Available in PDF, EPUB and Kindle. Book excerpt: The physical properties of ultrasound, particularly its highly directional beam behaviour, and its complex interactions with human tissues, have led to its becoming a vitally important tool in both investigative and interventional medicine, and one that still has much exciting potential. This new edition of a well-received book treats the phenomenon of ultrasound in the context of medical and biological applications, systematically discussing fundamental physical principles and concepts. Rather than focusing on earlier treatments, based largely on the simplifications of geometrical acoustics, this book examines concepts of wave acoustics, introducing them in the very first chapter. Practical implications of these concepts are explored, first the generation and nature of acoustic fields, and then their formal descriptions and measurement. Real tissues attenuate and scatter ultrasound in ways that have interesting relationships to their physical chemistry, and the book includes coverage of these topics. Physical Principles of Medical Ultrasonics also includes critical accounts and discussions of the wide variety of diagnostic and investigative applications of ultrasound that are now becoming available in medicine and biology. The book also encompasses the biophysics of ultrasound, its practical applications to therapeutic and surgical objectives, and its implications in questions of hazards to both patient and operator.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Sonochemistry and the Acoustic Bubble provides an introduction to the way ultrasound acts on bubbles in a liquid to cause bubbles to collapse violently, leading to localized 'hot spots' in the liquid with temperatures of 5000° celcius and under pressures of several hundred atmospheres. These extreme conditions produce events such as the emission of light, sonoluminescence, with a lifetime of less than a nanosecond, and free radicals that can initiate a host of varied chemical reactions (sonochemistry) in the liquid, all at room temperature. The physics and chemistry behind the phenomena are simply, but comprehensively presented. In addition, potential industrial and medical applications of acoustic cavitation and its chemical effects are described and reviewed. The book is suitable for graduate students working with ultrasound, and for potential chemists and chemical engineers wanting to understand the basics of how ultrasound acts in a liquid to cause chemical and physical effects. Experimental methods on acoustic cavitation and sonochemistry Helps users understand how to readily begin experiments in the field Provides an understanding of the physics behind the phenomenon Contains examples of (possible) industrial applications in chemical engineering and environmental technologies Presents the possibilities for adopting the action of acoustic cavitation with respect to industrial applications
