This valuable resource summarizes the past fifty years' basic research accomplishments in plasma dynamics for aerospace engineering, presenting these results in a comprehensive volume that will be an asset to any professional in the field. It offers a comprehensive review of the foundation of plasma dynamics while integrating the most recently developed modeling and simulation techniques with the theoretic physics, including the state-of-the-art numerical algorithms. Several first-ever demonstrations for innovations and incisive explanations for previously unexplained observations are included. All the necessary formulations for technical evaluation to engineering applications are derived from the first principle by statistic and quantum mechanics, and led to physics-based computational simulations for practical applications. The computer-aided procedures directly engage the reader to duplicate findings that are nearly impossible by using ground-based experimental facilities. Plasma Dynamics for Aerospace Engineering will allow readers to reach an incisive understanding of plasma physics.
Most natural and industrial flows are turbulent. The atmosphere and oceans, automobile and aircraft engines, all provide examples of this ubiquitous phenomenon. In recent years, turbulence has become a very lively area of scientific research and application, attracting many newcomers who need a basic introduction to the subject. An Introduction to Turbulent Flow, first published in 2000, offers a solid grounding in the subject of turbulence, developing both physical insight and the mathematical framework needed to express the theory. It begins with a review of the physical nature of turbulence, statistical tools, and space and time scales of turbulence. Basic theory is presented next, illustrated by examples of simple turbulent flows and developed through classical models of jets, wakes, and boundary layers. A deeper understanding of turbulence dynamics is provided by spectral analysis and its applications. The final chapter introduces the numerical simulation of turbulent flows. This well-balanced text will interest graduate students in engineering, applied mathematics, and the physical sciences.
Designed for introductory undergraduate courses in fluid mechanics for chemical engineers, this stand-alone textbook illustrates the fundamental concepts and analytical strategies in a rigorous and systematic, yet mathematically accessible manner. Using both traditional and novel applications, it examines key topics such as viscous stresses, surface tension, and the microscopic analysis of incompressible flows which enables students to understand what is important physically in a novel situation and how to use such insights in modeling. The many modern worked examples and end-of-chapter problems provide calculation practice, build confidence in analyzing physical systems, and help develop engineering judgment. The book also features a self-contained summary of the mathematics needed to understand vectors and tensors, and explains solution methods for partial differential equations. Including a full solutions manual for instructors available at www.cambridge.org/deen, this balanced textbook is the ideal resource for a one-semester course.

The site includes access to images, movies, programs, and moreThe computational aerodynamics concepts are given relevance by CA Concept Boxes integrated into the chapters to provide realistic asides to the conceptsReaders can see fluids in motion with the Flow Visualization Boxes carefully integrated into the text.
This book presents a focused, readable account of the principal physical and mathematical ideas at the heart of fluid dynamics. Graduate students in engineering, applied math and physics taking their first graduate course in fluids will find this book invaluable in providing the background in physics and mathematics necessary to pursue advanced study. The exposition follows an arc through the subject building towards a detailed derivation of the Navier–Stokes and energy equations followed by many examples of their use in studying the dynamics of fluid flows. Modern tensor analysis is used to simplify the mathematical derivations thus allowing a clearer view of the physics. The motivation behind many fundamental concepts such as Bernoulli's equation and the stream function are included. Many exercises are designed with a view toward using MATLAB® or equivalent to simplify and extend the analysis of fluid motion including developing flow simulations based on techniques described in the book.
Now in its third edition, Jet Propulsion offers a self-contained introduction to the aerodynamic and thermodynamic design of modern civil and military jet engine design. Through two-engine design projects for a large passenger and a new fighter aircraft, the text explains modern engine design. Individual sections cover aircraft requirements, aerodynamics, principles of gas turbines and jet engines, elementary compressible fluid mechanics, bypass ratio selection, scaling and dimensional analysis, turbine and compressor design and characteristics, design optimization, and off-design performance. The civil aircraft, which formed the core of Part I in the previous editions, has now been in service for several years as the Airbus A380. Attention in the aircraft industry has now shifted to two-engine aircraft with a greater emphasis on reduction of fuel burn, so the model created for Part I in this edition is the new efficient aircraft, a twin aimed at high efficiency.
The new edition of this popular textbook provides a modern, accessible introduction to the whole process of aircraft design from requirements to conceptual design, manufacture and in-service issues. Highly illustrated descriptions of the full spectrum of aircraft types, their aerodynamics, structures and systems, allow students to appreciate good and poor design and understand how to improve their own designs. Cost data is considerably updated, many new images have been added and new sections are included on the emerging fields of Uninhabited Aerial Vehicles and environmentally-friendly airlines. Examples from real aircraft projects are presented throughout, demonstrating to students the applications of the theory. Three appendices and a bibliography provide a wealth of information, much not published elsewhere, including simple aerodynamic formulae, an introduction to airworthiness and environmental requirements, aircraft, engine and equipment data, and a case study of the conceptual design of a large airliner.
Opening with recent advances in both the theoretical and physical models for wave-seabed-structure interactions, this book provides an updated look at the mathematics behind the interactions between sea, soil and man-made structures. The main models are broken down into key equations, and their strengths and challenges are discussed. These models are then placed in context with industry-relevant examples, in both two and three dimensions. From seabed instability around offshore wind turbines, to soil conditions in response to the laying of submarine pipelines, this book takes a comprehensive look at a variety of wave-seabed-structure interactions. With important implications for the future of offshore infrastructure, this is an ideal resource for industry workers, undergraduate students, and researchers.
Submarine pipelines play an extremely important role in the transportation of offshore energy resources, which is one of the main concerns of offshore engineering. In general, the fluctuating pressures acting upon the seabed due to the progressive motion of ocean waves will further induce excess pore pressure and reduce the effective stress within the seabed soil. When the excess pore pressure increases, the vulnerability of underwaterlaid pipelines may be exposed due to wave-induced liquefaction of underlying seabed soil layers. Therefore, the evaluation of the wave-induced soil response is particularly important for offshore engineers involved in the protective design of offshore pipelines.
Because of the existence of embedded pipelines, the generation of pore pressure in adjacent zones is quite different from that in the far field. Some experimental and numerical studies have been carried out to investigate the characteristics of oscillatory pore pressure near the pipeline, as well as the effects of wave and seabed parameters. Among these, Turcotte, Liu & Kulhawy (1984) conducted a series of wave tests to investigate the wave-induced oscillatory pore pressure around a buried pipeline. In their experiments, the pore pressures along the pipeline were measured. Cheng & Liu (1986) proposed a boundary-integral method to investigate the dynamic response of a seabed with a buried pipeline. In both of these approaches, the pipeline was buried in a rectangular trench layer with impermeable walls. Later, Madga (1996) proposed a one-dimensional simplified finite element model to investigate the wave-induced uplift seepage around a pipeline, which was further applied to investigate the seabed instability (Madga 1997). Based on Biot's (1941) poro-elastic theory, a two-dimensional finitedifference model was established for wave-seabed-pipe interactions in an isotropic homogeneous seabed (Jeng & Cheng 1999), which was further used to investigate seabed instability caused by liquefaction and shear failure around a pipeline (Jeng & Cheng 2000).
Based on the principle of repeatability (Zienkiewicz & Scott 1972), a finite element model was established for a Gibson soil (Jeng & Lin 1999b), a general non-homogeneous seabed (Jeng & Lin 1999a) and a cross-anisotropic seabed with a cover layer (Wang et al. 2000). With the same framework, the model was further extended by considering the pipeline as an elastic material to examine the internal stresses of the pipeline for different conditions (Jeng 2001c; Jeng, Postma & Lin 2001).
