Book Contraction Design for Small Low Speed Wind Tunnels

Download or read book Contraction Design for Small Low Speed Wind Tunnels written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-07 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: An iterative design procedure was developed for two- or three-dimensional contractions installed on small, low-speed wind tunnels. The procedure consists of first computing the potential flow field and hence the pressure distributions along the walls of a contraction of given size and shape using a three-dimensional numerical panel method. The pressure or velocity distributions are then fed into two-dimensional boundary layer codes to predict the behavior of the boundary layers along the walls. For small, low-speed contractions it is shown that the assumption of a laminar boundary layer originating from stagnation conditions at the contraction entry and remaining laminar throughout passage through the successful designs if justified. This hypothesis was confirmed by comparing the predicted boundary layer data at the contraction exit with measured data in existing wind tunnels. The measured boundary layer momentum thicknesses at the exit of four existing contractions, two of which were 3-D, were found to lie within 10 percent of the predicted values, with the predicted values generally lower. From the contraction wall shapes investigated, the one based on a fifth-order polynomial was selected for installation on a newly designed mixing layer wind tunnel.

Book Design of a Closed Jet Open Circuit Water Tunnel for the Study of Wake Mechanics

Download or read book Design of a Closed Jet Open Circuit Water Tunnel for the Study of Wake Mechanics written by Gerrit H. Toebes and published by . This book was released on 1958 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Technical Note describes the design of an open-circuit water tunnel with a 7-1/2 inch by 9 inch closed-jet working section. The maximum velocity obtainable in the empty test section is approximately 50 fps. The water tunnel was built for the purpose of investigating wakes behind objects placed in its test section. In particular, a study is to be made of the relationship between the trailing edge geometry of two-dimensional flat plates, the frequency of vortex shedding from them and the resulting elastic response of the plates when placed at zero angle of attack.

Book Analysis and Testing to Improve the Flow from the Plenum of a Subsonic Cascade Wind Tunnel

Download or read book Analysis and Testing to Improve the Flow from the Plenum of a Subsonic Cascade Wind Tunnel written by Richard Carl Moebius and published by . This book was released on 1980 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: The original design of the plenum and bellmouth contraction arrangement of a subsonic cascade test facility did not produce sufficiently uniform flow conditions at the bellmouth exit plane. Pneumatic measurements revealed sizeable-blade-to-blade variations in velocity and flow angle. A finite element numerical analysis of the inviscid flow field was carried out which both confirmed the need for and guided the design of a modification to the bellmouth contraction from the plenum. Following the modifications, in which the original contraction was changed to two two-dimensional contractions in series, and a program of development tests, acceptably small variations in velocity and flow angle were measured at the bellmouth exit plane.

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.
