This book was released on 1971 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hydrodynamic equations for relaxing fluids are used to derive the evolutionary properties of longitudinal plane waves of finite amplitude in dispersive and dissipative media. The regimes of uniform and secular perturbation solutions, representing either shock free or possibly shock like solutions, are determined from the equations with no restriction on the dispersion number. Solutions are calculated to second order to demonstrate the main features of the progressive wave distortion in nonlinear relaxing media. Heuristic theories using an equivalent viscous model of relaxing media are evaluated through comparison with the correct relaxation results. A consistent consideration of the perturbation method leads to a representation of the thermal state functions containing many parameters of nonlinearity which include the well known B/A parameter. Finally, through recourse to the theory of characteristics it is demonstrated that, unlike thermoviscous media, relaxing media may sustain true discontinuities in the flow similar to those occurring in the nondissipative Riemann solution.

Available in PDF, EPUB and Kindle. Book excerpt: The study of materials which exhibit new and unconventional properties is of central importance for the devel- opment of advanced and refined technologies in many fields of engineering science. In this connection there has been a rapidly growing interest in real fluid effects on wave phenomena in the past few years. A prominent example is provided by Bethe-Zel'dovich-Thompson (BZT) fluids which have the distinguishing feature that they exhibit negative nonlinearity over a finite range of temperature and pressures in the pure vapour phase. However, two phase flows with and without phase change are an even richer source of new unexpected and previously thought impossible phenomena. Topics covered by this volume include waves in gases near the critical point, waves in retrograde fluids, temperature waves in superfluid helium and density waves in suspensions of particles in liquids. Clearly, the aim of the various contributions is twofold. First, they are intended to provide scientists and engineers working in these and related areas with an overview of various new physical phenomena as for example expansion shocks, sonic shocks, shock splitting, evaporation and liquafaction shocks and the experimental techniques needed to study these phenomena. Second, an attempt is made to discuss aspects of their mathematical modeling with special emphasis on properties which these phenomena have in common.

Download or read book Propagation of Plane Compressional Waves of Finite Amplitude in Real Fluids a Theoretical Approach by the Method of Implicit Functions written by Yen Fu Bow and published by . This book was released on 1964 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theory is formulated describing the distortion of a plane, initially sinusoidal, compressional wave (or sound wave) of finite amplitude traveling through a real (nonlinear and dissipative) fluid medium which is initially undisturbed. The development of the theory consists of two steps. The first step is to find a closed-form approximate solution (expressed as an implicit functional relation) to the onedimensional hydrodynamical equations and the equation of the medium, and the second step is to improve this approximate solution by using certain physical insights. From the existence theorem of implicit functions a single condition is obtained from which the general behavior of sound propagation in a dissipative medium can be easily understood. The approximate solution found in the first step is in fairly good agreement with the experimental results and is compatible with previous theories. (Author).

Download or read book Understanding Acoustics written by Steven L. Garrett and published by Springer. This book was released on 2017-02-24 with total page 913 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides a unified approach to acoustics and vibration suitable for use in advanced undergraduate and first-year graduate courses on vibration and fluids. The book includes thorough treatment of vibration of harmonic oscillators, coupled oscillators, isotropic elasticity, and waves in solids including the use of resonance techniques for determination of elastic moduli. Drawing on 35 years of experience teaching introductory graduate acoustics at the Naval Postgraduate School and Penn State, the author presents a hydrodynamic approach to the acoustics of sound in fluids that provides a uniform methodology for analysis of lumped-element systems and wave propagation that can incorporate attenuation mechanisms and complex media. This view provides a consistent and reliable approach that can be extended with confidence to more complex fluids and future applications. Understanding Acoustics opens with a mathematical introduction that includes graphing and statistical uncertainty, followed by five chapters on vibration and elastic waves that provide important results and highlight modern applications while introducing analytical techniques that are revisited in the study of waves in fluids covered in Part II. A unified approach to waves in fluids (i.e., liquids and gases) is based on a mastery of the hydrodynamic equations. Part III demonstrates extensions of this view to nonlinear acoustics. Engaging and practical, this book is a must-read for graduate students in acoustics and vibration as well as active researchers interested in a novel approach to the material.

This book was released on 1989 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reflection and refraction of plane finite-amplitude waves at a plane interface between two fluids. The nonlinear equation for three-dimensional waves in a thermoviscous, relaxing fluid was derived. A second-order perturbation solution was obtained for the reflection-refraction problem for the case of a lossless fluid and an arbitrary source signal. Propagation in a periodic waveguide. Propagation has been measured in a plane wave tube loaded periodically with reactive branch elements. Experiments with small-signal waves verify in fine detail the dispersion relation that had been derived earlier (and this year modified to include thermoviscous boundary layer effects and the end correction for the branch elements). Scattering of sound by sound. Primary work had been on the role of source and boundary conditions. Experiments on single- beam and crossed-beams in the megahertz range is in progress. Ellipsoidal focusing. This work, which has applications to lithotripsy, is thus far mainly experimental. The experiments are carried out in air. An electric spark located at the near focus of an ellipsoidal reflector generates an N wave. The reflector concentrates the sound at the remote focus.
