Beschreibung

The automobile is an icon of modern technology because it includes most aspects of modern engineering, and it offers an exciting approach to engineering education. Of course there are many existing books on introductory fluid/aero dynamics but the majority of these are too long, focussed on aerospace and don’t adequately cover the basics. Therefore, there is room and a need for a concise, introductory textbook in this area.

Automotive Aerodynamics fulfils this need and is an introductory textbook intended as a first course in the complex field of aero/fluid mechanics for engineering students. It introduces basic concepts and fluid properties, and covers fluid dynamic equations. Examples of automotive aerodynamics are included and the principles of computational fluid dynamics are introduced. This text also includes topics such as aeroacoustics and heat transfer which are important to engineering students and are closely related to the main topic of aero/fluid mechanics.

This textbook contains complex mathematics, which not only serve as the foundation for future studies but also provide a road map for the present text. As the chapters evolve, focus is placed on more applicable examples, which can be solved in class using elementary algebra. The approach taken is designed to make the mathematics more approachable and easier to understand.

Key features:

• Concise textbook which provides an introduction to fluid mechanics and aerodynamics, with automotive applications
• Written by a leading author in the field who has experience working with motor sports teams in industry
• Explains basic concepts and equations before progressing to cover more advanced topics
• Covers internal and external flows for automotive applications
• Covers emerging areas of aeroacoustics and heat transfer

Automotive Aerodynamics is a must-have textbook for undergraduate and graduate students in automotive and mechanical engineering, and is also a concise reference for engineers in industry.

Series Preface

The automobile touches nearly every part of our lives. The manufacture of the automobile generates significant economic benefits, which is clear by the efforts that nations make to secure automobile manufacturing plants within their borders. Furthermore, issues such as emissions and fuel economy are critical to providing a sustainable path for the human race well into the future. Not only is the automobile a critical aspect of our lives, it is interwoven into our society, culture, and global wellbeing, as well as being a very fertile platform for tremendous technical advancements.

The primary objective of the Automotive Series is to publish practical and topical books for researchers, and practitioners in industry, and postgraduate/advanced undergraduate educators in the automotive engineering sector. The series addresses new and emerging technologies in automotive engineering supporting the development of more fuel efficient, safer and more environmentally friendly vehicles. It covers a wide range of topics, including design, manufacture, and operation, and the intention is to provide a source of relevant information that will be of interest and benefit to people working in the field of automotive engineering.

A critical aspect of vehicle system performance is the aerodynamic characteristics of the vehicle. These characteristics are major factors in vehicle performance, efficiency, safety, and marketability. This text, Automotive Aerodynamics, follows in the strong tradition of the Automotive Series, in that it presents classical fundamental concepts in aero and fluid mechanics in a pragmatic and concise fashion using the automobile as the primary exemplar. The text is designed to be used in an introductory aero/fluid mechanics course, and grounds the theoretical concepts in vehicle system examples that provide a familiar foundation to the students. Moreover, it does go beyond the basic aero/fluid topics addressing related issues such as heat-transfer, cooling, and aeroacoustics. Using the automobile as an example for these concepts provides the students with a critical touchstone to their life experiences.

Automotive Aerodynamics covers a number of classical topics including basic fluid mechanics, internal and external flows, viscosity and drag, as well as providing an introduction to numerical simulations, which are critical given the increasing access engineers have to cloud and high performance computing. Given that the text is well grounded in fundamentals, and has relevant and in-depth examples of modern systems, it is also a valuable professional reference. This book is an excellent text that is both relevant and forward thinking. It is written by a recognized expert in the field and is a welcome addition to the Automotive Series.

Preface

This text was planned for engineering students as a first course in the complex field of aero/fluid mechanics. It does contain complex math, mainly to serve as the foundation for future studies. But the chapters focus on more applied examples, which can be solved in class using elementary algebra. Thus, the intention is not to avoid complex physical problems, but to keep them simple. Therefore, emphasis is placed on providing complete solutions, which can be solved in class. The material provided is self-contained and the reader is not directed elsewhere for more detailed formulations. On the other hand, the automobile is a part of our everyday life and the first complete engineering system fascinating the younger generations. As such, focusing on automotive examples can provide the much needed inspiration, and accelerate the attention and learning curve of the students.

Aero/fluid mechanics is a complex science and some problems cannot be solved by simple intuition. The reason behind this is the complex nonlinear differential equations, which have no closed form solutions. Historically, simple models were developed for some specific cases, and one educational approach is to present a series of case studies based on those localized solutions. However, when following this approach, the connection among the case-studies is unclear and long term learning benefits diminish. In addition, numerical solutions matured recently and most CAD programs have modules that can generate “a solution” by a simple “run” command. This usually leads to an iterative “learning curve” without understanding the main variables affecting the solution. Therefore, presenting the governing equations early on (as painful as it can be), and explaining the possible simplifications will provide a clear roadmap that will pay-off at the end of the course.

The first objective of this text, as advocated in the previous paragraphs, is to provide a systematic approach to the field of aero/fluid mechanics and to serve as a long-term reference. Also, some engineering programs are forced to shorten the curriculum and require only one course related to thermo/fluid mechanics. Consequently, the second objective is
