Much-needed, fresh approach that brings a greater insight intothe physical understanding of aerodynamics Based on the author’s decades of industrial experiencewith Boeing, this book helps students and practicing engineers togain a greater physical understanding of aerodynamics. Relying onclear physical arguments and examples, Mclean provides amuch-needed, fresh approach to this sometimes contentious subjectwithout shying away from addressing "real" aerodynamic situationsas opposed to the oversimplified ones frequently used formathematical convenience. Motivated by the belief that engineeringpractice is enhanced in the long run by a robust understanding ofthe basics as well as real cause-and-effect relationships that liebehind the theory, he provides intuitive physical interpretationsand explanations, debunking commonly-held misconceptions andmisinterpretations, and building upon the contrasts provided bywrong explanations to strengthen understanding of the rightones. Provides a refreshing view of aerodynamics that is based on theauthor’s decades of industrial experience yet is alwaystied to basic fundamentals. Provides intuitive physical interpretations and explanations,debunking commonly-held misconceptions and misinterpretations Offers new insights to some familiar topics, for example, whatthe Biot-Savart law really means and why it causes so muchconfusion, what “Reynolds number” and“incompressible flow” really mean, and a real physicalexplanation for how an airfoil produces lift. Addresses "real" aerodynamic situations as opposed to theoversimplified ones frequently used for mathematical convenience,and omits mathematical details whenever the physical understandingcan be conveyed without them.

This outstanding thesis characterises the aerodynamic flow around a container freight train; investigating how changing container loading configurations affect the magnitude of aerodynamic forces measured on a container. 1/25th scale moving-model freight train experiments were carried out at the University of Birmingham’s TRAIN rig facility to investigate slipstream velocities and static pressure, as well as measuring, using a specifically designed on-board pressure monitoring system, the aerodynamic loads on containers. Results were compared with full scale data and assessed in terms European standards for trackside worker and passenger safety limits. Rail vehicle aerodynamic studies have tended to previously focus on high speed passenger trains in line with increases in train speed. The research presented within this thesis highlights the issues associated with the aerodynamic development around a freight train, providing the foundations for further research and a basis from which to develop international safety standards in relation to freight, as well as high speed trains.

From the Foreword: 'John Anderson's book represents a milestone in aviation literature. For the first time aviation enthusiasts - both specialists and popular readers alike - possess an authoritative history of aerodynamic theory. Not only is this study authoritative, it is also highly readable and linked to the actual (and more familiar) story of how the airplane evolved. The book touches on all the major theorists and their contributions and, most important, the historical context in which they worked to move the science of aerodynamics forward.' Von Hardesty, Smithsonian Institution From the reviews: 'Something of the unexpected quality of this book can be inferred from its full title A History of Aerodynamics and Its Impact on Flying Machines. Pilots tend to suppose that the science of aerodynamics began empirically, somewhere around the time of Lilienthal and the Wrights, and that aerodynamics and manned flight are roughly coeval. It is therefore surprising to come upon a photograph of the Wright Flyer as late as page 242 of the 478-page volume.' Peter Garrison, Flying 'This book successfully straddles the boundary that separates a text book from a history book. It is of equal interest to both the aerodynamicist and the layman. The textual balance achieved by the author has resulted in a book that is enjoyable and educational.' Earl See, American Aviation Historical Society Newsletter

Annotation This textbook and its six supporting computer programs provide theoretical modeling of the aerodynamic characteristics of wings and bodies at low Mach numbers. The approach presented directly helps engineering students improve problem-solving skills by teaching them to discern the necessary steps associated with solving analytical problems. The book also presents a justification and rationale for validating end results that leave the student with an understanding of the answer. The text differs from others by providing interactive computer programs that allow the student to conduct trade studies. It provides case-specific software that permits the student to do considerably more characteristic analysis of user-selected wings and bodies than is possible with other introductory textbooks. In addition, the algorithms are capable of working problems at a level well beyond those typically solved by hand in other textbooks. This approach allows students to determine easily the effects of modifying parameters and geometry. Another benefit of using this textbook is the understanding students gain of the capabilities of large industrial codes.

It is our pleasure to present these proceedings for “The Aerodynamics of Heavy Vehicles II: Trucks, Buses and Trains” International Conference held in Lake - hoe, California, August 26-31, 2007 by Engineering Conferences International (ECI). Brought together were the world’s leading scientists and engineers from industry, universities, and research laboratories, including truck and high-speed train manufacturers and operators. All were gathered to discuss computer simu- tion and experimental techniques to be applied for the design of the more efficient trucks, buses and high-speed trains required in future years. This was the second conference in the series. The focus of the first conference in 2002 was the interplay between computations and experiment in minimizing ae- dynamic drag. The present proceedings, from the 2007 conference, address the development and application of advanced aerodynamic simulation and experim- tal methods for state-of-the-art analysis and design, as well as the development of new ideas and trends holding promise for the coming 10-year time span. Also - cluded, are studies of heavy vehicle aerodynamic tractor and trailer add-on - vices, studies of schemes to delay undesirable flow separation, and studies of - derhood thermal management.

With major implications for applied physics, engineering, and the natural and social sciences, the rapidly growing area of environmental fluid dynamics focuses on the interactions of human activities, environment, and fluid motion. A landmark for the field, the two-volume Handbook of Environmental Fluid Dynamics presents the basic principles, fundamental flow processes, modeling techniques, and measurement methods used in the study of environmental motions. It also offers critical discussions of environmental sustainability related to engineering. The handbook features 81 chapters written by 135 renowned researchers from around the world. Covering environmental, policy, biological, and chemical aspects, it tackles important cross-disciplinary topics such as sustainability, ecology, pollution, micrometeorology, and limnology. Volume Two: Systems, Pollution, Modeling, and Measurements explores the interactions between engineered structures and anthropogenic activities that affect natural flows, with particular emphasis on environmental pollution. The book covers the numerical methodologies that underpin research, predictive modeling, and cyber-infrastructure developments. It also addresses practical aspects of laboratory experiments and field observations that validate quantitative predictions and help identify new phenomena and processes. As communities face existential challenges posed by climate change, rapid urbanization, and scarcity of water and energy, the study of environmental fluid dynamics becomes increasingly relevant. This volume is a valuable resource for students, researchers, and policymakers working to better understand environmental motions and how they affect and are influenced by anthropogenic activities.
