Download or read book Nonlinear Acoustics Long Range Underwater Propagation Noncollinear Interaction Reflection and Refraction and Subharmonic Generation written by David T. Blackstock and published by . This book was released on 1986 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: (1) Nonlinear effects in underwater propagation. Two analytical-computational projects in this area are: (a) long range propagation of finite-amplitude pulses in a stratified, dissipative ocean, and (b) the pressure, temperature, and salinity dependence of the nonlinearity coefficient beta and related quantities. (2) Nonlinear, noncollinear interaction of sound waves. Two analytical and experimental studies of interaction in a rectangular waveguide are described. First, a monochromatic wave is generated in the 1,0 model of the waveguide, and distortion produces a second harmonic component in the 2,0 mode, a third harmonic component in the 3,0 mode, etc. Second, two primary waves are generated, a low frequency wave in the 0,0 mode and a high frequency wave in the 1,0 mode. Of main interest are the sum and difference frequency waves produced by the nonlinear interaction of the two primaries. In a third study, which is not limited to waveguides, the angular dependence of the nonlinearity coefficient beta was investigated. (3) Reflection and refraction of finite-amplitude sound at a plane interface between two fluids. The purpose of this work is to determine two fluids. The purpose of this work is to determine the applicability of Snell's law, the law of specular reflection, and other familiar small-signal results when the incident wave is of finite amplitude. (4) Investigation of subharmonic generation and chaos in an acoustical resonance tube.
Download or read book Control of Acoustic Cavitation with Application to Lithotripsy written by and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Control of acoustic cavitation (sound-induced bubble activity) is the subject of this dissertation. Application is to clinical lithotripsy where cavitation contributes to kidney stone comminution and tissue damage. An electrical spark at the near focus of an underwater ellipsoidal reflector was the acoustical source, as in the Dornier HM3 lithotripter. Experiments were done with rigid reflectors, pressure-release reflectors, and pairs of reflectors sharing a common focus and a controlled delay between sparks. Since a bubble hit by a single shock pulse can grow profoundly and then collapse violently, our hypothesis was that a second pulse timed to arrive during the collapse phase would intensify the ultimate collapse. Experiments and numerical calculations confirmed the hypothesis. Pitted by bubble collapses, aluminum foil placed along the reflector axis recorded the spatial cavitation field. Tempered collapse was also discovered; a sufficiently short delay between two pulses or a change in order of the positive and negative phases of a single pulse stifled bubble growth. Early collapse was detected acoustically. Computations of bubble radius and collapse pressure reinforced the observations.
Download or read book Fundamentals of Physical Acoustics written by David T. Blackstock and published by John Wiley & Sons. This book was released on 2000-04-24 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: AN AUTHORITATIIVE, UP-TO-DATE INTRODUCTION TO PHYSICAL ACOUSTICS Easy to read and understand, Fundamentals of Physical Acoustics fills a long-standing need for an acoustics text that challenges but does not overpower graduate students in engineering and physics. Mathematical results and physical explanations go hand in hand, and a unique feature of the book is the balance it strikes between time-domain and frequency-domain presentations. Fundamentals of Physical Acoustics is intended for a two-semester, first-year graduate course, but is also suitable for advanced undergraduates. Emphasis on plane waves in the first part of the book keeps the mathematics simple yet accommodates a broad range of topics: propagation, reflection and transmission, normal modes and simple waveguides for rectilinear geometries, horns, inhomogeneous media, and sound absorption and dispersion. The second part of the book is devoted to a more rigorous development of the wave equation, spherical and cylindrical waves (including the more advanced mathematics required), advanced waveguides, baffled piston radiation, diffraction (treated in the time domain), and arrays. Applications and examples are drawn from: * Atmospheric acoustics * Noise control * Underwater acoustics * Engineering acoustics * Acoustical measurements Supplemented with more than 300 graphs and figures as well as copious end-of-chapter problems, Fundamentals of Physical Acoustics is also an excellent professional reference for engineers and scientists.

Chapters 1 through 8 develop the physical concepts, mathematical models, and classical methods of solution that form the theoretical framework for nonlinear acoustics. These chapters, or selected portions, form an appropriate core for an introductory course. While the emphasis is on nonlinear sound waves in fluids, Chapter 9 provides an introduction to nonlinear elastic waves in isotropic solids. Chapters 10 through 15 cover applications and additional methodologies encountered in nonlinear acoustics that include perturbation and numerical methods, ray theory for inhomogeneous media, statistical and parametric phenomena, and biomedical applications. The book is relevant to studies of therapeutic ultrasound, blast waves and jet noise, nondestructive testing, parametric array loudspeakers, particle manipulation with acoustic radiation force, and other applications involving nonlinear acoustics.

Available in PDF, EPUB and Kindle. Book excerpt: This volume includes revised and extended versions of selected papers presented at the Tenth International Symposium on Applications of Laser Techniques to Fluid Mechanics held at the Calouste Gulbenkian Foundation in Lisbon, during the period of July 10 to 13, 2000. The papers describe instrumentation developments for Velocity, Scalar and Multi-Phase Flows and results of measurements of Turbulent Flows, and Combustion and Engines. The papers demonstrate the continuing and healthy interest in the development of understanding of new methodologies and implementation in terms of new instrumentation. The prime objective of the Tenth Symposium was to provide a forum for the presentation of the most advanced research on laser techniques for flow measurements, and communicate significant results to fluid mechanics. The application of laser techniques to scientific and engineering fluid flow research was emphasized, but contributions to the theory and practice of laser methods were also considered where they facilitate new improved fluid mechanic research. Attention was placed on laser-Doppler anemometry, particle sizing and other methods for the measurement of velocity and scalars, such as particle image velocimetry and laser induced fluorescence.

Download or read book Sonochemistry and Sonoluminescence written by L.A. Crum and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sonochemistry is studied primarily by chemists and sonoluminescence mainly by physicists, but a single physical phenomenon - acoustic cavitation - unites the two areas. The physics of cavitation bubble collapse, is relatively well understood by acoustical physicists but remains practically unknown to the chemists. By contrast, the chemistry that gives rise to electromagnetic emissions and the acceleration of chemical reactions is familiar to chemists, but practically unknown to acoustical physicists. It is just this knowledge gap that the present volume addresses. The first section of the book addresses the fundamentals of cavitation, leading to a more extensive discussion of the fundamentals of cavitation bubble dynamics in section two. A section on single bubble sonoluminescence follows. The two following sections address the new scientific discipline of sonochemistry, and the volume concludes with a section giving detailed descriptions of the applications of sonochemistry. The mixture of tutorial lectures and detailed research articles means that the book can serve as an introduction as well as a comprehensive and detailed review of these two interesting and topical subjects.
