Available in PDF, EPUB and Kindle. Book excerpt: A brand-new edition of the classic guide on low-speed wind tunnel testing While great advances in theoretical and computational methods have been made in recent years, low-speed wind tunnel testing remains essential for obtaining the full range of data needed to guide detailed design decisions for many practical engineering problems. This long-awaited Third Edition of William H. Rae, Jr.'s landmark reference brings together essential information on all aspects of low-speed wind tunnel design, analysis, testing, and instrumentation in one easy-to-use resource. Written by authors who are among the most respected wind tunnel engineers in the world, this edition has been updated to address current topics and applications, and includes coverage of digital electronics, new instrumentation, video and photographic methods, pressure-sensitive paint, and liquid crystal-based measurement methods. The book is organized for quick access to topics of interest, and examines basic test techniques and objectives of modeling and testing aircraft designs in low-speed wind tunnels, as well as applications to fluid motion analysis, automobiles, marine vessels, buildings, bridges, and other structures subject to wind loading. Supplemented with real-world examples throughout, Low-Speed Wind Tunnel Testing, Third Edition is an indispensable resource for aerospace engineering students and professionals, engineers and researchers in the automotive industries, wind tunnel designers, architects, and others who need to get the most from low-speed wind tunnel technology and experiments in their work.

This book was released on 2013-03-09 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by TPRC at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemina tion phases of the activity was transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we have concluded that it will be in the interest of all concerned if the printing and distribution of the volume were handled by a well-known publishing house to assure improved service and better communication. Hence, effective with this Volume 18, Masters Theses in the Pure and Applied Sciences will be disseminated on a worldwide basis by Plenum Publishing Corporation of New York. All back issues can also be ordered from Plenum. As we embark on this new partnership with Plenum, we also initiate a new venture in that this important annual reference work now covers Canadian universities as well as those in the United States. We are sure that this broader base will greatly enhance the value of these volumes.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the present work is to determine the flow characteristics of the existing low-speed wind tunnel located in the Fluid Dynamics and Heat Transfer Laboratory and to correct any prominent unsatisfactory characteristics that might exist. A schematic diagram of the wind tunnel system is shown as figure 1 and its specifications are described in section II. The present investigation was initiated as a result of the wind tunnel being moved from a location wherein the blower was connected directly to the wind tunnel to its new location where space requirements dictated that a plenum chamber be placed between the blower and the tunnel. The plenum chamber causes the flow through it to be turned 90 degrees, thereby effecting a required decrease in the in-line length of the blower-tunnel combination. Additionally, the plenum chamber provides for access ports which can be utilized by other flow experiments using the same blower. As with any flow turning device, the introduction of the plenum chamber is expected to increase the losses through the system. In its former location, the tunnel had been evaluated with respect to attainable velocities, velocity profiles in the test section, and turbulence intensities. This evaluation, as accomplished by Sohn, showed that the tunnel performance was generally satisfactory and that the maximum obtainable test section velocity was 256 fps. However, after the tunnel was installed in its new location, the maximum velocity was observed in initial tests to be reduced to 180 fps; additionally, the tunnel appeared to be "rough" during operation at higher velocities. In view of the foregoing performance deterioration, some modifications in the tunnel configuration in its new location were clearly needed. First, the flow losses could be reduced by placing some turning vanes in the plenum chamber, which initially turned the flow 90 degrees without the aid of any interior surfaces. Secondly, it was reasoned that the "rough" sound of the wind tunnel might be the result of a resonance coupling between the main flow going through the plenum chamber and the rather large cavities existing both above and below the elevations where the wind tunnel and the blower join the plenum. It might be added that the plenum chamber was not designed in its 4' x 4' x 8' shape for its present use, but rather was available. This possible resonance problem was attacked by locating two 4' x 4' panels horizontally inside the plenum chamber so as to block off the unused portions of the plenum chamber. Details of these two major modifications are shown in figure 1. One additional improvement sought in the tunnel performance was a reduction in test section turbulence intensity. Such improvement was sought by adding a second 20 x 20 mesh screen in front of the single screen spanning the wind tunnel entrance. This addition, in conjunction with the foregoing modifications, resulted in the three following wind tunnel configurations for the current series of tests: Configuration #1 - As initially installed in the new location with no turning vanes or 4' x 4' panels and a single entrance screen; Configuration #2 - With turning vanes and panels in place and a single entrance screen; Configuration #3 - As in #2 with the exception of having two entrance screens. The particular evaluation tests which have been performed on the tunnel in this present project include the following: a. Measurements of center-line velocity in the test section for various louver openings (velocity levels) and tunnel configurations; b. Measurements of velocity profile across the test section at mid-height for various louver openings; c. Determination of center-line turbulence intensity in the test section for various louver openings and tunnel configurations; d. Determination of turbulence intensity across the test section at mid-height for various louver openings. In addition to the above tests, several oscillograph traces showing center-line velocity patterns as measured by a hot-wire anemometer were photographically recorded. Such recordings were made for different velocity levels and tunnel configurations, and they provide convenient quantitative insight into the tunnel performance.

Available in PDF, EPUB and Kindle. Book excerpt: A low speed wind tunnel was design and fabricate. The project covered the process of design and fabrication of the small wind tunnel. In completing this project, a computer aided drawing (CAD) called Solid Work is use to design the wind tunnel. Experiment conducted after build the wind tunnel to find drag coefficient of a sphere. The drag force on a sphere in an air stream was measured at various free stream velocities below 100 m/s. This was done in a low speed wind tunnel using an integral balance system to measure the drag force and a Pitot tube and to measure the velocity. The raw data were processed according to classical equations of fluid mechanics which define the drag coefficient. An impression of fluid field flow around a sphere is also capture using white smoke. Method of analysis the flow in test section was shown by using strings. The experimental results are compared to published results over the range tested.
