Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes the characterization of an inherently inhomogeneous medium capable of shear thickening. An aqueous suspension of cornstarch represents an important exemplar of such physical systems. The physics underlying the behavior of such shear thickening suspensions is incompletely understood. Characterization of these suspensions may provide valuable clues into the underlying mechanisms that result in shear thickening behavior. The goal of this thesis is to characterize the acoustic properties of suspensions of cornstarch in density-matched cesium chloride aqueous solutions. A review of the literature indicated that almost no information concerning the ultrasonic characteristics of suspensions of starches had been reported other than studies monitoring the gelatinization of starches not relevant to the shear stiffening of ungelatinized suspensions. Each chapter began with a discussion and validation of the specific experimental techniques and methods of analysis necessary for each type of measurement. Ultrasonic measurement of the group velocity, the frequency-dependent attenuation properties, the frequency-dependent phase velocity, and the frequency-dependent backscatter properties of the suspensions of cornstarch are reported. Initially counterintuitive results including negative (phase velocity) dispersion and a decrease in the measured backscatter coefficient with increasing particle concentration are understood in terms of widely accepted physical models. In sum, these studies represent an advancement of the understanding of the physics underlying the interaction between ultrasound and suspensions and lay the groundwork for future studies probing the physics of the shear thickening.

Available in PDF, EPUB and Kindle. Book excerpt: Ultrasonics International 93: Conference Proceedings presents a comprehensive account of the presentations given in the Ultrasonics International 93 conference. It discusses a blood flow mapping system using ultrasonic waves. It addresses the dynamical response functions of elastically anisotropic solids. Some of the topics covered in the book are the ultrasonic waves propagation in a liquid producing radicals; ultrasonic characterization of interfaces; surface acoustic wave measurements; line-focus-beam acoustic microscopy; investigation of fatigue cracks in steels using spherical lens scanning acoustic microscopy; and the phenomenon of ultrasonic light diffraction. The description of bichromatic tunable acousto-optic separator is fully covered. The diffraction phenomenon affecting the properties of the fibre-optic sensor system is discussed in detail. The text describes in depth the opto-acoustic measurement of ultrasound velocity in a solidifying polymer. The evaluation of microfracture due to thermal shock using acoustic emission is completely presented. A chapter is devoted to the detection of a weak adhesive and adherent interface in bonded joints. The book can provide useful information to engineers, students, and researchers.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The study of the ultrasonic properties of liquid mixtures at different temperatures is of great importance in various fields of science and engineering, including chemistry, physics, materials science, and chemical engineering. Ultrasonic waves are mechanical waves with frequencies above the range of human hearing, and they have been widely used in the investigation of the physical and chemical properties of liquids. By analyzing the behavior of ultrasonic waves in liquid mixtures, it is possible to obtain information on various properties such as acoustic velocity, attenuation, refraction, absorption, and molecular interactions, which can be used to understand the structure and behavior of the liquid mixtures. In this context, the study of the ultrasonic properties of liquid mixtures at different temperatures can provide valuable insights into the behavior of the mixtures under different conditions and has important implications for a wide range of applications.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the results of three main experimental projects; a study of ultrasonic wave propagation in strongly scattering materials, the use of the results of this first study to develop new techniques in ultrasonic correlation spectroscopy, and the use of these techniques to measure the dynamics of particles in fluidized beds. The first project involves the investigation of wave propagation in random, inhomogeneous materials that scatter ultrasound strongly (i.e. materials where the scattering mean free path is comparable to the ultrasonic wavelength [lambda]). I have measured the velocities of the weak ballistic pulse that travels through these materials without scattering out of the forward direction. Using the results of this wave propagation study, we have developed two new ultrasonic spectroscopy techniques. Dynamic Sound Scattering (DSS) uses singly scattered sound to measure the rms velocity of scatterers. Diffusing Acoustic Wave Spectroscopy (DAWS) uses multiply scattered sound, describedby the diffusion approximation, to measure the relative motion of scatterers. This thesis explains the underlying principles governing these techniques and the ways that these techniques can be implemented in practice to provide powerful new methods for investigating the dynamics of strongly scattering materials. Using DAWS and DSS, I have investigated the dynamics of particles suspended against sedimentation by a fluid flowing upwards in a fluidized bed. Since ultrasonic wavelengths are on the order of millimeters, the suspensions that can be Probed contain particles with diameters on the millimeter scale; this corresponds to a regime that is of interest in industrial applications. Thus DAWS and DSS are well suited to the high Reynolds number, high volume fraction suspensions to which other current techniques are least suited. In our experiments, the velocity fluctuations and velocity correlation lengths are measured as a function of the volume fraction and sampl.
