Book Description
Unsteady flow effects observed on a vehicle are to be distinguished according to the character of the oncoming flow. This flow can be in steady state as during a cruise in calm weather - or in a wind tunnel. Unsteady flow may originate from abrupt changes at otherwise steady conditions of the oncoming flow, and it may be caused by fully turbulent oncoming flow, having a boundary layer velocity profile. Up to quite recently vehicle aerodynamics has dealt with the latter two phenomena only, if at all. However, unsteadiness of flow may be the origin of higher forces and moments, either stochastic or periodic - with a frequency content close to the natural frequencies of a body and/or chassis, and may modulate wind noise in a way to impair comfort. Contents: Character of the oncoming flow - Description of unsteady flows - Large scale fluctuations - Vehicle and driver in cross wind - Generation of unsteady flows in experiments - Measurements in unsteady flows - Numerical simulation of unsteady flows

Book Description
The detailed presentation of fundamental aerodynamics principles that influence and improve vehicle design have made Aerodynamics of Road Vehicles the engineer’s “source” for information. This fifth edition features updated and expanded information beyond that which was presented in previous releases. Completely new content covers lateral stability, safety and comfort, wind noise, high performance vehicles, helmets, engine cooling, and computational fluid dynamics. A proven, successful engineering design approach is presented that includes: • Fundamentals of fluid mechanics related to vehicle aerodynamics • Essential experimental results that are the ground rules of fluid mechanics • Design strategies for individual experimental results • General design solutions from combined experimental results The aerodynamics of passenger cars, commercial vehicles, motorcycles, sports cars, and race cars is dealt with in detail, inclusive of systems, testing techniques, measuring and numerical aerodynamics methods and simulations that significantly contribute to vehicle development. Aerodynamics of Road Vehicles is an excellent reference tool and an indispensable source for the industry’s vehicle engineers, designers, and researchers, as well as for enthusiasts, students, and those working in academia or government regulatory agencies.

Book Description
Aerodynamics has never been more central to the development of cars, commercial vehicles, motorbikes, trains and human powered vehicles, driven by the need for efficiency: reducing carbon dioxide emissions, reducing fuel consumption, increasing range and alleviating problems associated with traffic congestion. Reducing vehicle weight makes it more challenging to ensure that they are stable and handle well over a wide range of environmental conditions. Lighter structures are also more vulnerable to aerodynamically induced vibration. Alongside this, customers demand an environment that is quiet, comfortable and maintains their vision of the world around them in all weathers. These aims must be met by designing vehicles that engage customers emotionally, promoting the brand values of manufacturers and operators. This can only be done by collaboration between designers and aerodynamicists. - Examine the latest developments in vehicle aerodynamic development - Explore opportunities to network and share experiences around different areas - Focus on future challenges and the engineering knowledge and technology required to resolve them - Discuss other areas of development including handling and stability, tyre aerodynamics and modelling, aeroacoustics and fluid structure interaction

Book Description
In this book, the author introduces the concept of unsteady aerodynamics and its underlying principles. He provides the readers with a comprehensive review of the fundamental physics of free and forced unsteadiness, the terminology and basic equations of aerodynamics ranging from incompressible flow to hypersonics. The book also covers modern topics related to the developments made in recent years, especially in relation to wing flapping for propulsion. The book is written for graduate and senior year undergraduate students in aerodynamics and also serves as a reference for experienced researchers. Each chapter includes ample examples, questions, problems and relevant references. The treatment of these modern topics has been completely revised end expanded for the new edition. It now includes new numerical examples, a section on the ground effect, and state-space representation.
