Available in PDF, EPUB and Kindle. Book excerpt: Wind Tunnel Test Techniques: Design and Use at Low and High Speeds with Statistical Engineering Applications provides an up-to-date treatment of the topic. Beginning with a brief history of wind tunnels and its types and uses, the book goes on to cover subsonic, supersonic and hypersonic wind tunnel design and construction, calibration, boundary corrections, flow quality assessment, pressure surveys, and dynamic testing. It also focuses on wind tunnel facilities, making it useful for both the designer and operator. Engineers and graduate students in aerospace, automotive and similar programs will find this book useful in their work with experimental aerodynamics, gas dynamics, facility design and performance. Deals with a broad range of flow speeds in wind tunnels, from low speed to high speed Provides a discussion of similarity laws as well as material on statistical analysis Includes coverage on facility-to-facility and facility-to-CFD correlation Presents advanced topics such as cryogenic wind tunnels, ground simulation in automotive testing, and propulsion testing

Available in PDF, EPUB and Kindle. Book excerpt: Tests have been conducted in a number of NASA wind tunnels to measure disturbance levels and spectra in their respective settling chambers, test sections, and diffusers to determine the sources of these disturbances. Results indicate that properly designed and located second minimums in transonic tunnels prevent pressure fluctuations originating at struts and in diffusers from propagating upstream into the test section. The installation in or upstream of the settling chamber of carefully selected screens, honeycomb, and acoustic baffles could further reduce test section turbulence levels and scales without significant pressure losses. The performance of these modifications will be strongly influenced by tunnel geometry and its influence on the mean flow around the circuit.

Available in PDF, EPUB and Kindle. Book excerpt: A cooperative effort between the Office National d'Etudes et de Recherches Aerospatiales (ONERA); the National Aeronautic and Space Administration, Ames Research Center (NASA-ARC); and the Arnold Engineering Development Center (AEDC) was accomplished whereby two ONERA standard calibration models (M3 and M5) and an area equivalent body of revolution (C5) were tested in the NASA-ARC 11-ft and the AEDC 16-ft and 4-ft transonic wind tunnels. The tests were designed to provide an experimental data base for (1) the evaluation of theoretical or empirical wall-interference correction factors and (2) the establishment of guidelines to allow reasonable selection of wind tunnel to model size ratios in the transonic speed regime. The results showed that large effects of Reynolds number, tunnel flow quality, and small difference in model geometry preclude a determination of wall interference from the M3 and M5 model data. The primary cause of the data differences is a variation in the wing shock/separation patterns between the three tunnel tests. Even though the model forces may, in certain instances, agree from tunnel to tunnel, pressure distributions showed the agreement to be fortuituous. The C5 model data indicated subsonic theory underpredicts the required blockage correction by a factor of two to ten and, because the blockage interference effect changes sign along the model, simply correcting the Mach number will not compensate for the transonic interference.
