This is the first text devoted exclusively to the subject of nonsteady, compressible, internal flow theory and the application of this theory to practical devices. The need for such a text has become apparent with the availability of commercial equipment dependent upon this type of flow phenomena. The book is usable both as a text for graduate level courses and as an introduction for readers wishing to become familiar with nonsteady flow phenomena and their practical applications. This audience consists of mechanical, chemical, and aerospace engineers; and specialists in fluid mechanics. The first and second chapters are introductory in nature, aiming to assist readers conversant with the concepts of steady flow to adjust to unfamiliar events and circumstances while avoiding the finer details of algebraic manipulation. A generalized derivation of the classical method-of-characteristics as applied to one-dimensional, nonsteady, internal flows is included in chapter three. Chapter four is devoted to a study of the various boundary conditions necessary for handling a wide range of problems. Chapter five deals with methods of solution including both graphical and numerical procedures. The remaining five chapters explore specific fields of application. These include pipeline flows, dynamic pressure exchangers, pulse combusters and the tuning of the exhaust and induction systems of reciprocating, and Wankel type, internal combustion engines. Additional nonsteady flow devices are described in the last chapter. All the latter chapters are supported by appropriate references to available literature, including the basic material presented in the first half of the book. When necessary, additional specialized theoretical material is included in each of the special-topics applications-oriented chapters. In order to fulfill the needs of graduate students and their instructors, worked examples are included in addition to exercise problems.

One-dimensional Compressible Flow is an introduction to compressible flow. The book covers the main concepts from thermodynamics and fluid mechanics, including the continuity and momentum equations and the laws of thermodynamics; the steady flow with area change, friction, or heat transfer; and the one-dimensional steady flow. The text also gives an introduction to the method of characteristics for solving unsteady flow problems. Charts and tables are provided in the book for performing steady flow calculations. The book is useful to students pursuing a degree course in mechanical engineering and practicing mechanical engineer.

New Edition Now Covers Shock-Wave Analysis An in-depth presentation of analytical methods and physical foundations, Analytical Fluid Dynamics, Third Edition breaks down the "how" and "why" of fluid dynamics. While continuing to cover the most fundamental topics in fluid mechanics, this latest work emphasizes advanced analytical approaches to aid in the analytical process and corresponding physical interpretation. It also addresses the need for a more flexible mathematical language (utilizing vector and tensor analysis and transformation theory) to cover the growing complexity of fluid dynamics. Revised and updated, the text centers on shock-wave structure, shock-wave derivatives, and shock-produced vorticity; supersonic diffusers; thrust and lift from an asymmetric nozzle; and outlines operator methods and laminar boundary-layer theory. In addition, the discussion introduces pertinent assumptions, reasons for studying a particular topic, background discussion, illustrative examples, and numerous end-of-chapter problems. Utilizing a wide variety of topics on inviscid and viscous fluid dynamics, the author covers material that includes: Viscous dissipation The second law of thermodynamics Calorically imperfect gas flows Aerodynamic sweep Shock-wave interference Unsteady one-dimensional flow Internal ballistics Force and momentum balance The Substitution Principle Rarefaction shock waves A comprehensive treatment of flow property derivatives just downstream of an unsteady three-dimensional shock Shock-generated vorticity Triple points An extended version of the Navier‒Stokes equations Shock-free supersonic diffusers Lift and thrust from an asymmetric nozzle Analytical Fluid Dynamics, Third Edition outlines the basics of analytical fluid mechanics while emphasizing analytical approaches to fluid dynamics. Covering the material in-depth, this book provides an authoritative interpretation of formulations and procedures in analytical fluid dynamics, and offers analytical solutions to fluid dynamic problems.

This much-needed monograph presents a systematic, step-by-step approach to the continuum modeling of flow phenomena exhibited within materials endowed with a complex internal microstructure, such as polymers and liquid crystals. By combining the principles of Hamiltonian mechanics with those of irreversible thermodynamics, Antony N. Beris and Brian J. Edwards, renowned authorities on the subject, expertly describe the complex interplay between conservative and dissipative processes. Throughout the book, the authors emphasize the evaluation of the free energy--largely based on ideas from statistical mechanics--and how to fit the values of the phenomenological parameters against those of microscopic models. With Thermodynamics of Flowing Systems in hand, mathematicians, engineers, and physicists involved with the theoretical study of flow behavior in structurally complex media now have a superb, self-contained theoretical framework on which to base their modeling efforts.

The analysis of compressible viscous flow in a two-dimensional adiabatic channel is made by means of a boundary layer approximation. In particular, two-dimensional laminar flow within parallel adiabatic walls is treated. Some solutions were obtained which are in agreement with the results of more conventional one-dimensional flow analysis as far as pressure gradient and choking length are concerned. However, in the well-behaved cases profile changes involving popping and reverse flow are observed. This can be explained on the basis of non-uniformity in density and momentum over the cross section. Another set of cases which exhibit more unusual behavior are obtained. They are largely associated with positive pressure gradients in subsonic flow and negative pressure gradients in supersonic flow. It is observed that, due to nonuniform velocity, the flow may be partially supersonic and partially subsonic over a section. Mathematically, the initial pressure gradient can be prescribed in this analysis. Therefore, the unusual pressure gradient cited can be obtained in principle. The physical significance of the unusual solutions are discussed. (Author).
