Download or read book Ultrasonic Nondestructive Evaluation written by Tribikram Kundu and published by CRC Press. This book was released on 2003-12-29 with total page 848 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most books on ultrasonic nondestructive evaluation (NDE) focus either on its theoretical background or on advanced applications. Furthermore, information on the most current applications, such as guided wave techniques and acoustic microscopy, is scattered throughout various conference proceedings and journals. No one book has integrated these aspects into a treatment that is both self-contained and up-to-date. Ultrasonic Nondestructive Evaluation: Engineering and Biological Material Characterization brings together the principles, equations, and applications of ultrasonic NDE, both traditional and state-of-the-art, in a single, authoritative resource. It begins with the relevant fundamentals of mechanics, derives the basic equations of the mechanics of elastic wave propagation, and then, step-by-step, covers the advanced topics and applications of ultrasonic NDE that are at the forefront of today's research. These include engineering, biological, and clinical applications, such as structural health monitoring, the characterization of biological cells, and real-time blood flow measurement. Written in plain language by some of the world's leading experts, the chapters are filled with case studies, worked examples, and exercises that help make this book an outstanding resource for course work, as well as for reference. If you are looking for that one book that can bring you quickly up-to-speed on the principles, technologies, and latest applications of ultrasonic NDE, look no further than this book.

Download or read book Characterization of Liquids Nano and Microparticulates and Porous Bodies using Ultrasound written by Andrei S. Dukhin and published by Elsevier. This book was released on 2010-06-03 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two key words define the scope of this book: 'ultrasound' and 'colloids'. Historically, there has been little real communication between practitioners in these two fields. Although there is a large body of literature devoted to ultrasound phenomenon in colloids, there is little recognition that such phenomena may be of real importance for both the development and applications of colloid science. On the other side, colloid scientists have not embraced acoustics as an important tool for characterizing colloids. The lack of any serious dialogue between these scientific fields is the biggest motivation behind this book. Covers in detail this multidisciplinary field combining acoustics, electroacoustics, colloid science, analytical chemistry and rheology Provides a bibliography with more than 1,000 references Presents theories and their experimental verification, as well as analysis of the methods and hardware pertaining to applications such as pharmaceuticals, ceramics, and polymers

Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the results of an investigation into the design parameters of an externally mounted ultrasonic cross correlation flowmeter. A set of operational requirements are presented for the acoustical system and from these requirements a theoretical design is formulated for the ultrasonic transducer. The selection of an operating frequency is shown to depend on the operational requirements and both the transducer design and operating frequency are shown to be interdependent. Construction of the transducer is shown to affect the mode of operation and the governing relationship is presented. Transducers built to the theoretical design are tested in practice and shown to meet the operational requirements. A study of transducer mountings to pipe sections is also presented and in the light of experimental evidence an improved method of transducer mounting is outlined. Efficient methods of coupling the electrical energy into the transducer and the acoustical energy into the pipe section are investigated. Also, two methods of assessing a given transducer's characteristics are explained and their shortcomings highlighted. Further, it is shown that the selection of a high operating frequency overcomes the problems of acoustical cross-talk between the two transmitted ultrasonic beams. The determination of a suitable method of demodulating the received signal is investigated, both theoretically and practically. The theoretical results show that in a closed conduit, amplitude modulation of an ultrasonic beam will predominate. Practical observations confirm this and the expected modulation levels are achieved. The practical results also show that an amplitude demodulated signal is less susceptible to interference by extraneous noise such as that produced by plant vibrations. These results are confirmed for all the flowmeter configurations tested. A closed loop control scheme using a phase locked loop system is developed, whereby the flowmeter will be able to compensate for environmental changes. Three combinations of this system are presented and their poor performance and inability to control the flowmeter, investigated and explained. The analysis used to explain the above is extended to develop a further control scheme using a phase shift network in one channel of the flowmeter. This system is shown to be more stable and controllable than previous systems and is less susceptible to extraneous noise. A closed loop control scheme incorporating a system of this type is presented. Suggestions are made to further investigate the selection of operating frequency, transducer mounting and to determine the most suitable strategy for implementing a phase shift type closed loop control scheme.

Download or read book Ultrasonic Methods in Solid State Physics written by Rohn Truell and published by Academic Press. This book was released on 2013-10-22 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrasonic Methods in Solid State Physics is devoted to studies of energy loss and velocity of ultrasonic waves which have a bearing on present-day problems in solid-state physics. The discussion is particularly concerned with the type of investigation that can be carried out in the megacycle range of frequencies from a few megacycles to kilomegacycles; it deals almost entirely with short-duration pulse methods rather than with standing-wave methods. The book opens with a chapter on a classical treatment of wave propagation in solids. This is followed by separate chapters on methods and techniques of ultrasonic pulse echo measurements, and the physics of ultrasonically measurable properties of solids. It is hoped that this book will provide the reader with the special background necessary to read critically the many research papers and special articles concerned with the use of ultrasonic methods in solid state physics. The book is intended to help the person beginning work in this field. At the same time, it will also be useful to those actively involved in such work. An attempt has been made to provide a fairly general and unified treatment suitable for graduate students and others without extensive experience.

Download or read book Physical Principles of Ultrasonic Technology written by L. Rozenberg and published by Springer. This book was released on 2012-04-18 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under the action of acoustic vibrations a liquid is converted into the aerosol state at the interface between a gaseous and a liq uid medium. Acoustic energy can be delivered to the atomization zone either on the liquid side or on the gas side. Ordinarily, when acoustic energy is delivered through the gas, the atomization of the liquid is realized by sonic and low-frequency ultrasonic vibra tions because high-frequency ultrasound is rapidly damped in prop agation through gases. But if the acoustic energy is delivered through the liquid, whose damping factor is orders of magnitude smaller than in gases, atomization can be realized by sonic, low frequency ultrasonic, or high-frequency ultrasonic vibrations. The following is a convenient classification of methods for the ultra sonic atomization of a liquid: 1. atomization of the liquid with the transmission of acoustic energy to the working zone through the liquid: a. atomization in a layer; b. atomization in a fountain; 2. atomization of the liquid with the transmission of acoustic energy to the working zone through the gas. 3 Chapter 1 Acoustic Atomization of Liquids The atomization of liquids by ultrasound (at a frequency of 300 kHz) was discovered in the classical studies of Wood and Loomis [1]. The first experimental investigation of the physical nature of the 8tomization of a liquid by ultrasound was conducted by Sollner [2].
