Complex fluid flows are encountered widely in nature, in living beings and in engineering practice. These flows often involve both geometric and dynamic complexity and present problems that are difficult to analyse because of their wide range of length and time scales, as well as their geometric configuration. This book describes some computational techniques and modelling strategies for analysing and predicting complex transport phenomena. It summarizes advances in the context of a pressure-based algorithm. Among methods discussed are discretization schemes for treating convection and pressure, parallel computing, multigrid methods, and composite, multiblock techniques. With respect to physical modelling, the book addresses issues of turbulence closure and multiscale, multiphase transport from an engineering viewpoint. Both fundamental and practical issues are considered, along with the relative merits of competing approaches. Numerous examples are given throughout the text. Mechanical, aerospace, chemical and materials engineers can use the techniques presented in this book to tackle important, practical problems more effectively.

Many of the significant issues in fluid dynamics occur at interfaces, that is, at the boundaries between differing fluids or between fluids and solids. These issues are important in areas ranging from aircraft flight, to the flow of blood in the heart, to chemical vapour deposition. The subject is an area of active research and development, owing to improved analytical, experimental, and computational techniques. This book describes research and applications in interfacial fluid dynamics and stability. It is organized around five topics: Benard and thermocapillary instabilities, shear and pressure induced instabilities, waves and dispersions, multiphase systems, and complex flows. Chapters have been contributed by internationally recognized experts, both theoreticians and experimentalists. Because of the range and importance of topics discussed, this book will interest a broad audience of graduate students and researchers in mechanical, aerospace, materials, and chemical engineering, as well as in applied mathematics and physics.

Low Reynolds number aerodynamics is important to a number of natural and man-made flyers. Birds, bats, and insects have been of interest to biologists for years, and active study in the aerospace engineering community, motivated by interest in micro air vehicles (MAVs), has been increasing rapidly. The focus of this book is the aerodynamics associated with fixed and flapping wings. The book considers both biological flyers and MAVs, including a summary of the scaling laws which relate the aerodynamics and flight characteristics to a flyer's sizing on the basis of simple geometric and dynamics analyses, structural flexibility, laminar-turbulent transition, airfoil shapes, and unsteady flapping wing aerodynamics. The interplay between flapping kinematics and key dimensionless parameters such as the Reynolds number, Strouhal number, and reduced frequency is highlighted. The various unsteady lift enhancement mechanisms are also addressed.

This book describes the principles and equations required for evaluating the performance of an aircraft. After introductory chapters on the atmosphere, basic flight theory and drag, the book goes on to consider in detail the estimation of climbing performance, the relevant characteristics of power plants, take-off and landing performance, range and turning performance. There is then a short account of the use of vectored thrust and a final chapter on transonic and supersonic flight. The emphasis is on deriving and applying simple analytical expressions rather than on computations from extensive numerical data, but all the exemplary calculations refer to current types of aircraft and the few necessary data are provided. The greater part of the book refers to subsonic aircraft flying at subcritical speeds, which can be dealt with using relatively simple equations, but it is shown that some of this simplicity can be carried over to transonic and supersonic speeds.

Berlin offers an in-depth look into all the engineering aspects of geostationary satellite design, construction, and launch. Geostationary satellites have opened new doors for the peaceful use of outer space. From vantage points 22,000 miles above the equator, they permit people anywhere on land, at sea, or in the air to communicate with each other, and they provide meteorologists, geologists, and other scientists with photographs of the earth. This book gives equal emphasis to the explanation of launch vehicles, orbital mechanics, the space environment, spacecraft structures, mechanisms, thermal control, telemetry tracking and command, communications technology, meterological payloads, product assurance and testing.

Aircraft Noise traces the origins of this problem to the introduction of the jet engine into the airline fleet in the late 1950s and describes the legal restrictions now placed on the industry. It explains the derivation of the special noise units and assessment scales now used around the world; noise exposure modeling and forecasting; the major sources of aircraft noise and their control; and noise measurement and prediction, including contours. Finally, it offers a forecast for the future and recommends changes to the established legal structures to aid control of the problem into the next century. In addition to reviewing the sociological aspects, Smith offers a broad understanding of the problem of aircraft noise and its control. The book should appeal to a variety of people including professional engineers, local and national government officers, the air transport business community, lawyers, students, community leaders and those who live near airports.

Satellites are used increasingly in telecommunications, scientific research, surveillance, and meteorology, and these satellites rely heavily on the effectiveness of complex onboard control systems. This 1997 book explains the basic theory of spacecraft dynamics and control and the practical aspects of controlling a satellite. The emphasis throughout is on analyzing and solving real-world engineering problems. For example, the author discusses orbital and rotational dynamics of spacecraft under a variety of environmental conditions, along with the realistic constraints imposed by available hardware. Among the topics covered are orbital dynamics, attitude dynamics, gravity gradient stabilization, single and dual spin stabilization, attitude maneuvers, attitude stabilization, and structural dynamics and liquid sloshing.

The definitive reference for space engineers on rendezvous and docking/berthing (RVD/B) related issues, this book answers key questions such as: How does the docking vehicle accurately approach the target spacecraft? What technology is needed aboard the spacecraft to perform automatic rendezvous and docking, and what systems are required by ground control to supervise this process? How can the proper functioning of all rendezvous-related equipment, systems and operations be verified before launch? The book provides an overview of the major issues governing approach and mating strategies, and system concepts for rendezvous and docking/berthing. These issues are described and explained such that aerospace engineers, students and even newcomers to the field can acquire a basic understanding of RVD/B. The author would like to extend his thanks to Dr Shufan Wu, GNC specialist and translator of the book's Chinese edition, for his help in the compilation of these important errata.

This is an ideal book for graduate students and researchers interested in the aerodynamics, structural dynamics and flight dynamics of small birds, bats and insects, as well as of micro air vehicles (MAVs), which present some of the richest problems intersecting science and engineering. The agility and spectacular flight performance of natural flyers, thanks to their flexible, deformable wing structures, as well as to outstanding wing, tail and body coordination, is particularly significant. To design and build MAVs with performance comparable to natural flyers, it is essential that natural flyers' combined flexible structural dynamics and aerodynamics are adequately understood. The primary focus of this book is to address the recent developments in flapping wing aerodynamics. This book extends the work presented in Aerodynamics of Low Reynolds Number Flyers (Shyy et al. 2008).
