Advanced Engineering Fluid Mechanics

Fluid mechanics continues to dominate the world of engineering. This book bridges the gap between first and higher level text books on the subject. It shows that the approximate approaches are essentially globally averaged versions of the local treatment, that in turn is covered in considerable detail in the second edition.

Fluid mechanics is the study of how fluids behave and interact under various forces and in various applied situations, whether in liquid or gas state or both. The author of Advanced Fluid Mechanics compiles pertinent information that are introduced in the more advanced classes at the senior level and at the graduate level. “Advanced Fluid Mechanics courses typically cover a variety of topics involving fluids in various multiple states (phases), with both elastic and non-elastic qualities, and flowing in complex ways. This new text will integrate both the simple stages of fluid mechanics (“Fundamentals ) with those involving more complex parameters, including Inviscid Flow in multi-dimensions, Viscous Flow and Turbulence, and a succinct introduction to Computational Fluid Dynamics. It will offer exceptional pedagogy, for both classroom use and self-instruction, including many worked-out examples, end-of-chapter problems, and actual computer programs that can be used to reinforce theory with real-world applications. Professional engineers as well as Physicists and Chemists working in the analysis of fluid behavior in complex systems will find the contents of this book useful. All manufacturing companies involved in any sort of systems that encompass fluids and fluid flow analysis (e.g., heat exchangers, air conditioning and refrigeration, chemical processes, etc.) or energy generation (steam boilers, turbines and internal combustion engines, jet propulsion systems, etc.), or fluid systems and fluid power (e.g., hydraulics, piping systems, and so on)will reap the benefits of this text. Offers detailed derivation of fundamental equations for better comprehension of more advanced mathematical analysis Provides groundwork for more advanced topics on boundary layer analysis, unsteady flow, turbulent modeling, and computational fluid dynamics Includes worked-out examples and end-of-chapter problems as well as a companion web site with sample computational programs and Solutions Manual

Fluid mechanics continues to dominate the world of engineering. Applications only seem to be proliferating, and the importance of teaching the subject from first principles is widely felt. The second edition maintained this focus, while continuing to establish the link between principles and practice. The Third edition includes a substantial revision of Chapter 2. The link between a control volume approach and a boundary-value formulation stemming from Navier-Stokes equations is explained. The utility of momentum and energy equations for analysis at the scale of a control volume is highlighted. Bernoulli equation is shown to be a special form of the more general energy equation. Various suggestions and improvements have also been incorporated in other chapters. The goal, as before, is to train students so that they can create, design and analyze flow systems in the real world. This book was first published in 1996, and a revised edition was released in 1999. Quite a few comments and suggestions were received from students and colleagues. These ideas formed the basis of the second edition in 2005. The present edition continues to bridge the gap between first and higher level text books on the subject. It shows that the approximate approaches of Chapter 2 are essentially globally averaged versions of the local treatment that, in turn is covered in considerable detail in subsequent chapters. NEW TO THE THIRD EDITION: - Link between a control volume approach and a boundary-value formulation arising from Navier-Stokes equations - Utility of momentum and energy equations for analysis at the scale of a control volume - Bernoulli equation shown to be a special form of the more general energy equation - Examples of flow rate and force calculations from a control volume approach - Additional unsolved examples in Chapter 2

The current book, Advanced Fluid Mechanics and Heat Transfer is based on author's four decades of industrial and academic research in the area of thermofluid sciences including fluid mechanics, aero-thermodynamics, heat transfer and their applications to engineering systems. Fluid mechanics and heat transfer are inextricably intertwined and both are two integral parts of one physical discipline. No problem from fluid mechanics that requires the calculation of the temperature can be solved using the system of Navier-Stokes and continuity equations only. Conversely, no heat transfer problem can be solved using the energy equation only without using the Navier-Stokes and continuity equations. The fact that there is no book treating this physical discipline as a unified subject in a single book that considers the need of the engineering and physics community, motivated the author to write this book. It is primarily aimed at students of engineering, physics and those practicing professionals who perform aero-thermo-heat transfer design tasks in the industry and would like to deepen their knowledge in this area. The contents of this new book covers the material required in Fluid Mechanics and Heat Transfer Graduate Core Courses in the US universities. It also covers the major parts of the Ph.D-level elective courses Advanced Fluid Mechanics and Heat Transfer that the author has been teaching at Texas A&M University for the past three decades.

Physics of Continuous Matter: Exotic and Everyday Phenomena in the Macroscopic World, Second Edition provides an introduction to the basic ideas of continuum physics and their application to a wealth of macroscopic phenomena. The text focuses on the many approximate methods that offer insight into the rich physics hidden in fundamental continuum mechanics equations. Like its acclaimed predecessor, this second edition introduces mathematical tools on a "need-to-know" basis. New to the Second Edition This edition includes three new chapters on elasticity of slender rods, energy, and entropy. It also offers more margin drawings and photographs and improved images of simulations. Along with reorganizing much of the material, the author has revised many of the physics arguments and mathematical presentations to improve clarity and consistency. The collection of problems at the end of each chapter has been expanded as well. These problems further develop the physical and mathematical concepts presented. With worked examples throughout, this book clearly illustrates both qualitative and quantitative physics reasoning. It emphasizes the importance in understanding the physical principles behind equations and the conditions underlying approximations. A companion website provides a host of ancillary materials, including software programs, color figures, and additional problems.

The contents of this book covers the material required in the Fluid Mechanics Graduate Core Course (MEEN-621) and in Advanced Fluid Mechanics, a Ph. D-level elective course (MEEN-622), both of which I have been teaching at Texas A&M University for the past two decades. While there are numerous undergraduate fluid mechanics texts on the market for engineering students and instructors to choose from, there are only limited texts that comprehensively address the particular needs of graduate engineering fluid mechanics courses. To complement the lecture materials, the instructors more often recommend several texts, each of which treats special topics of fluid mechanics. This circumstance and the need to have a textbook that covers the materials needed in the above courses gave the impetus to provide the graduate engineering community with a coherent textbook that comprehensively addresses their needs for an advanced fluid mechanics text. Although this text book is primarily aimed at mechanical engineering students, it is equally suitable for aerospace engineering, civil engineering, other engineering disciplines, and especially those practicing professionals who perform CFD-simulation on a routine basis and would like to know more about the underlying physics of the commercial codes they use. Furthermore, it is suitable for self study, provided that the reader has a sufficient knowledge of calculus and differential equations. In the past, because of the lack of advanced computational capability, the subject of fluid mechanics was artificially subdivided into inviscid, viscous (laminar, turbulent), incompressible, compressible, subsonic, supersonic and hypersonic flows.

Advanced Engineering Thermodynamics, Second Edition is a five-chapter text that covers some basic thermodynamic concepts, including thermodynamic system equilibrium, thermodynamic properties, and thermodynamic application to special systems. Chapter 1 introduces the concept of equilibrium, maximum work of thermodynamic systems, development of Gibbs and Helmholtz functions, thermodynamic system equilibrium, and conditions for stability and spontaneous change. Chapter 2 deals with the general thermodynamic relations for systems of constant chemical composition; the development of Maxwell relations; the derivatives of specific heats; coefficients of h, p, T, Clausius-Clapeyron equations; the Joule-Thomson effect; and application of van der Waals gas-inversion curves to liquefaction system. Chapters 3 and 4 describe the thermodynamics of ideal gases, ideal gas mixtures, and gas mixtures with variable composition. These chapters also discuss processes involving dissociation-Lighthill ideal dissociating gas, extension to ionization and real gas effects, and characteristics of "frozen" and equilibrium flows. Chapter 5 surveys the thermodynamics of elastic systems, surface tension, magnetic systems, reversible electrical cell, and fuel cell. This chapter also provides an introduction to irreversible thermodynamics, Onsager reciprocal relation, and the concept of thermoelectricity. This book will prove useful to undergraduate mechanical engineering students and other engineering students taking courses in thermodynamics and fluid mechanics.
