Book Description
Small amplitude resonant motions of an inviscid, polytropic gas, contained in a tube of finite length, are investigated. It is postulated that motion of the gas may be represented as the super-position of two small amplitude simple waves which interact only at the boundaries. As a result, the problem reduces to solving a nonlinear difference equation, and this is effected on the basis that the solution is in the neighborhood of a linear standing wave. A consequence is that waves progress as acoustic waves, but the signal carried is determined by a nonlinear equation. The problems considered are the determination of the motion of the gas which is being forced at a resonant frequency at one end of a tube, while the other end may be open or closed. Self-sustained oscillations for these cases are also treated. For these resonant motions, the amplitude of the motion at particles away from the ends is greater than that of the driving mechanism. When the end of the tube is closed, shocks are a feature of the solution. For an open end, the motion is continuous. (Author)

Book Description
Oscillations of gas and/or liquid columns in a flow channel can lead to various phenomena such as Stirling cycle heat engines, pulse tube refrigerators, as well as thermally induced gas oscillations like Sondhauss tube and Rijke tube. Although those phenomena may look different from each other, they can be universally described by the concepts of work flow and heat flow. Work flow stands for the acoustic power used in acoustics. Heat flow is the energy flow associated with the hydrodynamic transport of entropy. These energy flows help us to understand the thermoacoustic phenomena and construct acoustical heat engines.The book aims to provide a comprehensive overview of how the oscillations of gas and/or liquid columns make possible the mutual energy conversions between work flow and heat flow through thermal interactions between fluids and channel walls. The thermodynamic aspects of energy flows are highlighted by introducing Lagrangian point of view to explain the thermodynamic cycles that the fluid parcels undergo. The relevant experimental results are provided to verify the theoretical analysis based on basic equations of fluid dynamics.

Book Description
This updated new edition provides an introduction to the field of thermoacoustics. All of the key aspects of the topic are introduced, with the goal of helping the reader to acquire both an intuitive understanding and the ability to design hardware, build it, and assess its performance. Weaving together intuition, mathematics, and experimental results, this text equips readers with the tools to bridge the fields of thermodynamics and acoustics. At the same time, it remains firmly grounded in experimental results, basing its discussions on the distillation of a body of experiments spanning several decades and countries. The book begins with detailed treatment of the fundamental physical laws that underlie thermoacoustics. It then goes on to discuss key concepts, including simple oscillations, waves, power, and efficiency. The remaining portions of the book delve into more advanced topics and address practical concerns in applications chapters on hardware and measurements. With its careful progression and end-of-chapter exercises, this book will appeal to graduate students in physics and engineering as well as researchers and practitioners in either acoustics or thermodynamics looking to explore the possibilities of thermoacoustics. This revised and expanded second edition has been updated with an eye to modern technology, including computer animations and DeltaEC examples.
