Automotive Aerodynamics Joseph Katz, San Diego State University, USA 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.

Modifying the Aerodynamics of Your Road Car is a unique handbook that assumes no starting knowledge of vehicle aerodynamics. It begins with simple ideas and finishes with sophisticated and effective aerodynamic modifications that work. Three major chapters cover on-road testing techniques that give you all the information you need to decide what modifications you should make - and, after you’ve made them, how well they work. Low-cost techniques allow you to visualize the patterns of airflow over your car so that you can actually see the problem areas that need improvement. Uniquely, you’re also shown how to measure aerodynamic pressures, so you can determine which body surfaces are creating lift, drag and downforce. Want to work out where a wing should be placed? On-road testing to find that out is covered as well. The book also shows you how to measure downforce to see if that wing is actually working! If you wish to reduce drag, more than ten different areas are covered. Reducing frontal area, lowering cooling system drag, optimizing vehicle ride height and rake, reducing the strength of the wake, achieving clean airflow separation and optimizing wheel designs are all covered using the latest research findings. And if you’re a performance driver, there’s a major chapter devoted to reducing lift and improving stability. This chapter includes the design and development of undertrays and diffusers, wings and spoilers. The example car developed measurable downforce when fitted with an undertray and rear diffuser, something that transformed its on-road handling. The author has been writing about the aerodynamics of road cars for more than 25 years. He is also an experienced and proficient car modifier who has performed numerous aerodynamic modifications and upgrades to his own cars. The book’s technical consultant, RH Barnard, is an acknowledged world leading automotive aerodynamicist. If you want a practical, hands-on guide that demystifies and explains car aerodynamics, and shows you how to make effective aerodynamic modifications to your car, this book is for you.

Die aerodynamische Gestaltung von Brücken, Hochhäusern, Zügen und Bahnen oder Kraftfahrzeugen ist äußerst schwierig. Ihre Umströmung wird - typisch für stumpfe Körper - von Ablösungen geprägt und deren Verhalten lässt sich nur mit großem Aufwand voraussagen. Lange Zeit erfolgte das ausschließlich experimentell; zunehmend kommen nun aber auch numerische Verfahren zum Einsatz. In jedem Fall erfolgt die Optimierung all dieser Körper nach dem Prinzip von Versuch und Irrtum. Will man dabei schnell zum Ziel kommen, dann erweist es sich als nützlich, das vorliegende Problem auf einen möglichst einfachen Modellfall zurückzuführen. Die Gesetzmäßigkeiten der Umströmung geometrisch so einfacher Körper wie Kreiszylinder und Kugel, Keil und Kegel sowie Quader sind eingehend erforscht worden. Mit Umsicht lassen sie sich auf komplexere Formen übertragen. Das Buch stellt die dazu erforderlichen Grundlagen bereit.

This work serves as a reference concerning the automotive chassis, i.e. everything that is inside a vehicle except the engine and the body. It is the result of a decade of work mostly done by the FIAT group, who supplied material, together with other automotive companies, and sponsored the work. The first volume deals with the design of automotive components and the second volume treats the various aspects of the design of a vehicle as a system.

Leistung, Fahrverhalten und Komfort eines Automobils werden nachhaltig von seinen aerodynamischen Eigenschaften bestimmt. Ein niedriger Luftwiderstand ist die Voraussetzung dafür, dass die hochgesteckten Verbrauchziele erreicht werden. Die Aerodynamik des Automobils ist 1981 erstmalig erschienen und seitdem zu einem Standardwerk geworden. Der Stoff ist von Praktikern erarbeitet worden, die aus einer Vielzahl von Versuchen strömungsmechanische Zusammenhänge ableiten und Strategien beschreiben.Bei unveränderter Geamtkonzeption wurden für die 6. Auflage neue Ergebnisse zum induzierten Widerstand und zur Haltung der Fahrtrichtung bei Seitenwind aktualisiert. Völlig neu wurden die Kapitel über Kühlung und Durchströmung(HVAC) sowie über numerische Methoden wie CFD, Netzgenerierung und CAD erarbeitet.

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.
