Download or read book Absorption and Dispersion of Ultrasonic Waves written by Karl F. Herzfeld and published by Academic Press. This book was released on 2013-10-22 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: Absorption and Dispersion of Ultrasonic Waves focuses on the influence of ultrasonics on molecular processes in liquids and gases, including hydrodynamics, energy exchange, and chemical reactions. The book first offers information on the Stokes-Navier equations of hydrodynamics, as well as equations of motion, viscosity, formal introduction of volume viscosity, and linearized wave equation for a nonviscous fluid. The manuscript then ponders on energy exchange between internal and external degrees of freedom as relaxation phenomenon; effect of slow energy exchange on sound propagation; different ways of evaluating the dispersion curve; and exact calculation of absorption and dispersion. The text examines the effects of chemical reactions, thermodynamic theory of relaxation, and mixtures. The book also evaluates the absorption of high intensity sound waves, ratio of relaxation absorption to classical absorption at maximum, and gas mixtures. Discussions also focus on translational relaxation in monatomic gases, linear triatomic molecules, and results for rotational relaxation. The manuscript is a dependable source of data for readers interested in the absorption and dispersion of ultrasonic waves.

Download or read book Physical Acoustics and Metrology of Fluids written by Martin Trusler and published by CRC Press. This book was released on 2020-11-25 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interaction of sound waves with the medium through which they pass can be used to investigate the thermophysical properties of that medium. With the advent of modern instrumentation, it is now possible to determine the speed and absorption of sound with extremely high precision and, through the dependence of those quantities on variables like temperature, pressure, and frequency to gain a sensitive measure of one or more properties of fluid. This has led to renewed interest in such measurements and in the extraction of thermophysical properties of gases and liquids there from. Physical Acoustics and Metrology of Fluids describes both how to design experiments to achieve the highest possible accuracy and how to relate the quantities measured in those experiments to the thermophysical properties of the medium. A thorough theoretical examination of the alternative experimental methods available is designed to guide the experimentalist toward better and more accurate methods. This theoretical analysis is enhanced and complemented by an in-depth discussion of practical experimental techniques and the problems inherent within them. Bringing together the fields of thermodynamics, kinetic theory, fluid mechanics, and theoretical acoustics, plus a wealth of information about practical instruments, this book represents an essential reference on the design and execution of valuable experiments in fluid metrology and physical acoustics.

Download or read book Temperature and Frequency Dependence of Ultrasonic Absorption in Liquid Helium Below 1k written by W. A Jeffers (Jr) and published by . This book was released on 1965 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: From measurements of the temperature dependence of the amplitude of ultrasonic pulses propagated over a fixed path in liquid helium, the attenuation coefficient has been determined at the six frequencies 1.00, 2.02, 3.91, 6.08, 10.2, and 11.7 Mc/sec, at temperatures extending down to 0.2K. Below 0.6K, the observed variation of the absorption coefficient a (1/cm) with frequency f (Mc/sec) and temperature T (K) can be represented by the empirical equation a=0.11 (f to the 2/3 power)(Tcubed). This behavior differs from that predicted by several existing theories that are based upon the threephonon or four-phonon interaction between longitudinal acoustic quanta and thermal phonons. Over the temperature interval 0.6-0.8K, the measured attenuation is somewhat greater than would be expected from an extrapolation of the results below 0.6K into this temperature region. A comparison of the data with some calculations by Khalatnikov suggests that the additional absorption arises from thermal conduction in the normal fluid. An equation that is analogous to the classical Kirchhoff expression adequately accounts for this contribution to the total absorption, even at temperatures for which the lifetime of the thermal phonons exceeds the period of the sound wave.

Download or read book Analysis of Ultrasonic Absorption Measurements in Liquids at High Pressures written by Walter H. Johnson (Jr.) and published by . This book was released on 1967 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method, complete with error analysis, is given for determining the absorption coefficient for ultrasonic pulses (alpha) and the loss at the mirror and crystal (gamma) as a function of pressure. Results of the analysis are presented for distilled water as well as n-propanol. An expression for the pressure-dependent mirror-crystal loss is derived and checked against the experimental values obtained. In addition, a second method, which uses the expression for gamma, is discussed which enables one to obtain the absorption coefficient more directly from fewer measurements. (Author).

Download or read book Physical Principles of Medical Ultrasonics written by C. R. Hill and published by John Wiley & Sons. This book was released on 2005-08-05 with total page 528 pages. 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.
