The book "Wind Tunnels and Experimental Fluid Dynamics Research" is comprised of 33 chapters divided in five sections. The first 12 chapters discuss wind tunnel facilities and experiments in incompressible flow, while the next seven chapters deal with building dynamics, flow control and fluid mechanics. Third section of the book is dedicated to chapters discussing aerodynamic field measurements and real full scale analysis (chapters 20-22). Chapters in the last two sections deal with turbulent structure analysis (chapters 23-25) and wind tunnels in compressible flow (chapters 26-33). Contributions from a large number of international experts make this publication a highly valuable resource in wind tunnels and fluid dynamics field of research.

This Handbook helps to design and build any kind of force measurement equipment for the use in a wind tunnel. It is of interest to those who want to build multi-component force measurement sensors for other applications as well. The book describes the basic relations for the design and presents handbook formulas that can be used to perform a primary determination of main dimensions of a specified multi-component force sensor. This Handbook describes material and manufacturing particularities, instrumentation techniques and methods for the compensation of environmental influences. It also discusses calibration problems of multi-component force sensors and methods for the evaluation of the data.

Oliver Fischer analyzes the interference effects occurring in free-stream wind tunnels as well as their correction and simulation. With this work, the investigated correction method and the comparability of its results as well as flow simulation results are improved. The model wind tunnel of the IVK, University of Stuttgart, is simulated in various wind tunnel configurations. The application of a correction procedure to the corresponding experimental data from the model wind tunnel of the IVK is examined. These correction results are directly comparable with interference-free simulation results and thus allow a conclusion on the functionality of the correction method. Based on these findings, this thesis proposes a modification of the correction method that improves the comparability of corrected experimental results and CFD simulations in idealized test conditions. About the Author Oliver Fischer works as an engineer in aerodynamics development for a renowned German automobile manufacturer.

The present study was performed to determine how significant the interference effects of the wind-tunnel model support system and tunnel walls can be for a high-speed configuration during takeoff and landing conditions. A 5-percent scale model of the Technology Concept Airplane was recently tested in the Langley 14- by 22-Foot Subsonic Tunnel. The model was numerically modeled with and without the support and tunnel walls and compared with experimental data. Detailed analysis of the flow provided additional insight concerning what effects the postsupport and tunnel walls had on the flow field. This study revealed that although the overall forces and moments could be experimentally accounted for, the detailed flow features, such as the surface pressure distributions, could not be accurately simulated without including the post in the computations.

This book presents experimental techniques in the field of aerodynamics, a discipline that is essential in numerous areas, such as the design of aerial and ground vehicles and engines, the production of energy, and understanding the wind resistance of buildings. Aerodynamics is not only concerned with improving the performance and comfort of vehicles, but also with reducing their environmental impact. The book provides updated information on the experimental and technical methods used by aerodynamicists, engineers and researchers. It describes the various types of wind tunnels – from subsonic to hypersonic – as well as the problems posed by their design and operation. The book also focuses on metrology, which has allowed us to gain a detailed understanding of the local properties of flows, and examines current developments toward creating a methodology combining experiments and numerical simulations: the computer-assisted wind tunnel. Lastly, it offers an overview of experimental aerodynamics based on a prospective vision of the discipline, and discusses potential futures challenges. The book can be used as a textbook for graduate courses in aerodynamics, typically offered to students of aerospace and mechanical engineering programs, and as a learning tool for professionals and engineers in the fields of aerodynamics, aeronautics and astronautics automobile.
