Theory and Applications of Aerodynamics for Ground Vehicles



Independent Book Publishers Association (IBPA) Benjamin Franklin Silver Award Recipient, Professional & Technical Category

This best-selling book provides an introduction to ground vehicle aerodynamics and methodically guides the reader through the various aspects of the subject. Those needing specific information or a refresher can easily jump to the material of interest. There is a particular emphasis on various vehicle types (passenger cars, trucks, trains, motorcycles, race cars, etc.). However, the book is focused on cars and trucks, which are the most common vehicles in the speed range in which the study of ground vehicle aerodynamics is beneficial.

Readers will gain a fundamental understanding of the topic, which will help them design vehicles that have improved aerodynamics; this will lead to better fuel efficiency, improved performance, and increased passenger comfort.

The author’s basic approach to the presentation of the material is complemented with review questions, application questions, exercises, and suggested projects at the end of most of the chapters, which helps the reader apply the information presented, either in the classroom or for self-study.

Aside from offering a solid understanding of ground vehicle aerodynamics, the book also offers more thorough study of several key topics. One such topic is car-truck interaction, when one vehicle (usually the smaller one) is overtaking the other. There is a direct and instant benefit in terms of safety on the highway from understanding the forces at play when one vehicle passes the other in the same direction and sense.

Read Reviews
"From my many years of reviewing of textbooks, I found this particular title easy to read, and fundamentally easy to grasp the concepts it covers. The author took his time to explain the theory of aerodynamics necessary to understand preliminary and detailed design of ground vehicles.

Dr. Obidi captured the noise produced in vehicles as he categorizes them in terms of aerodynamic, environmental and interactive noise production. His explanations are apt for the audiences he is targeting, undergraduate and Master’s degree students. The book is very applicable for industry use as well. The material presented on vehicle-to-vehicle interactions on the road is helpful, as is the vehicle-to-environment interaction. The focus on heat transfer, internal aerodynamics and cooling systems is important to a holistic design concept.

In all, this book is useful to mechanical, aerospace, civil, design engineers, and even petroleum engineers who often deal with wind-wave interactions. "
