Low Speed Water Tunnels. Design, Fabrication and Analysis


Book Description

Project Report from the year 2016 in the subject Engineering - Civil Engineering, grade: AA, Priyadarshini College of Engineering, Nagpur, course: B.E AERONAUTICAL ENGINEERING, language: English, abstract: This text depicts how a low speed water tunnel was designed and fabricated, as well as tested and analysed. The low speed recirculating type water tunnel was successfully designed and fabricated. The designing was done by taking into consideration of the Reynolds no. flow velocity, boundary layer formation, cavitation number and Froude's number. Theoretical and computational studies were made to decide the shape and the size of the various components of the low speed water tunnel. Uniformity in the setup of main objective and was successfully achieved. The setup consists of an inlet plenum with baffle to reduce turbulence or splashing, honeycomb structure, converging section, test section and wide angle diffuser and outlet module suitable low power single phase motor was selected for continuous flow of water in the setup. The water was recirculated using this motor and appropriate plumbing system. All the components were designed, analyzed, constructed and installed successfully .General purpose polymer was used as a ground material for the fabrication purpose. Necessary up gradations were made during various stages of the project. Flow visualization over the test bodies was successfully visualized using a dye injection system.

Low-Speed Wind Tunnel Testing


Book Description

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.




Techniques of Flow Visualization


Book Description

The techniques of flow visualization and their application in wind tunnels, water channels, and experiments related to propulsion research are reviewed. These techniques can be classified roughly into three major groups: Surface flow visualization, scattering from flow tracers, and density sensitive flow visualization. The progress in laser optics and the wide-spread use of computers has led to the development of new techniques and evaluation procedures, which are included in the review; e.g. laser-induced fluorescence, speckle photography, image processing, and optical tomography. Emphasis is given to the discussion of the physical background of the methods. Information on technical details is provided by means of a number of sample photographs and by respective references.




Flow Visualization


Book Description

This is the 2nd edition of the book, Flow Visualization: Techniques and Examples, which was published by Imperial College Press in 2000. Many of the chapters have been revised and updated to take into consideration recent changes in a number of flow visualization and measurement techniques, including an updated high quality flow gallery. Unique among similar publications, this book focuses on the practical rather than theoretical aspects. Obtaining high quality flow visualization results is, in many ways, more of an art than a science, and experience plays a key deciding role. The depth and breadth of the material will make this book invaluable to readers of all levels of experience in the field.




Fluid Mechanics Measurements


Book Description

This revised edition provides updated fluid mechanics measurement techniques as well as a comprehensive review of flow properties required for research, development, and application. Fluid-mechanics measurements in wind tunnel studies, aeroacoustics, and turbulent mixing layers, the theory of fluid mechanics, the application of the laws of fluid mechanics to measurement techniques, techniques of thermal anemometry, laser velocimetry, volume flow measurement techniques, and fluid mechanics measurement in non-Newtonian fluids, and various other techniques are discussed.




Flow Visualization VI


Book Description

Over the last decade, flow visualization has advanced in step with the progress in laser and computer technologies. The scope of the International Symposium on Flow Visualiza- tion will be broader than ever, covering the range of infor- mation generally thought of as nonvisual and reflecting the inclusion of computer - aided methodologies. The Sixth In- ternational Symposium on Flow Visualization aims to attract the participation of experts and users of flow viualizing techniques on furthering an advanced philosophy for the de- velopment of the methods and their applications.
