This book was released on 2013-07-30 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is our pleasure to present these proceedings from the United Engineering Foundation Conference on The Aerodynamics of Heavy Vehicles: Trucks, Buses and Trains held December 2-6, 2002, in Monterey, California. This Department of Energy, United Engineering Foundation, and industry sponsored conference brought together 90 leading engineering researchers from around the world to discuss the aerodynamic drag of heavy vehicles. Participants from national labs, academia, and industry, including truck manufacturers, discussed how computer simulation and experimental techniques could be used to design more fuel efficient trucks, buses, and trains. Conference topics included comparison of computational fluid dynamics calculations using both steady and unsteady Reynolds-averaged Navier-Stokes, large-eddy simulation, and hybrid turbulence models and experimental data obtained from the Department of Energy sponsored and other wind tunnel experiments. Advanced experimental techniques including three-dimensional particle image velocimetry were presented, along with their use in evaluating drag reduction devices. We would like to thank the UEF conference organizers for their dedication and quick response to sudden deadlines. In addition, we would like to thank all session chairs, the scientific advisory committee, authors, and reviewers for their many hours of dedicated effort that contributed to a successful conference and resulted in this document of the conference proceedings. We also gratefully acknowledge the support received from the United Engineering Foundation, the US Department of Energy, Lawrence Livermore National Laboratory, Volvo Trucks America, International Truck and Engine Corporation, and Freightliner LLC.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains papers presented at the International conference “The Aerodynamics of Heavy Vehicles III: Trucks, Buses and Trains” held in Potsdam, Germany, September 12-17, 2010 by Engineering Conferences International (ECI). Leading scientists and engineers from industry, universities and research laboratories, including truck and high-speed train manufacturers and operators were brought together to discuss computer simulation and experimental techniques to be applied for the design of more efficient trucks, buses and high-speed trains in the future. This conference was the third in the series after Monterey-Pacific Groove in 2002 and Lake Tahoe in 2007.The presentations address different aspects of train aerodynamics (cross wind effects, underbody flow, tunnel aerodynamics and aeroacoustics, experimental techniques), truck aerodynamics (drag reduction, flow control, experimental and computational techniques) as well as computational fluid dynamics and bluff body, wake and jet flows.

This book was released on 2018 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: While performance ground vehicles run in a highly dynamic environment, aerodynamic evaluation through wind tunnel tests and the computer simulation analyses are mostly performed under static condition. Study of a coupling relationship between stability of the vehicles and influences of unsteady aerodynamics during the high-speed turns was conducted by the numerical analysis. Two vehicle models were subjected to study under simplified turn motions in the numerical domain by implementing with Eulerian based approach, and the unsteady aerodynamic forces and moments acting on the vehicles were predicted by transient flow solver utilizing Reynolds-Averaged Navier-Stokes equations and compared to the steady cases. A significant correlation between the cornering performance and effects of unsteady aerodynamics on the vehicleâ€TMs stability during the high-speed turns was suggested along with introducing Hypotheses. The unsteady feature of the aerodynamic forces is mainly proposed by altering the CP location due to flow separations and shedded vortices around the bodies. From this research,although no evidence was able to found for relative change in the CP location, the remarkable overshoots and phase lags were identified in the predicted unsteady aerodynamic forces, which were not observed in the steady cases. The external flow fields were examined in order to determine a correlation between the unsteady aerodynamic forces and the unsteady flow characteristics. Although some indications of the correlation were found near surface of the pressure recovery region around aft of the bodies, negative and low total pressures dominate the external flow field around the bodies due to bluff-body aerodynamics and high Reynolds numbers for the both time-averaged and transient cases.Under those circumstances, determination of the clear correlation has left the researcher huge challenge.

Download or read book Fluid Structure Sound Interactions and Control written by Marianna Braza and published by Springer Nature. This book was released on 2021-05-05 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a thorough and unique record of recent advances in the important scientific fields fluid–structure interaction, acoustics and control of priority interest in the academic community and also in an industrial context regarding new engineering designs. It updates advances in these fields by presenting state-of-the-art developments and achievements since the previous Book published by Springer in 2018 after the 4th FSSIC Symposium. This book is unique within the related literature investigating advances in these fields because it addresses them in a complementary way and thereby enhances cross-fertilization between them, whereas other books treat these fields separately.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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
