Experiments with a Model Water Tunnel


Book Description

This report describes a model water tunnel built in 1928 to investigate the possibility of using water tunnels for aerodynamics investigations at large scales. The model tunnel is similar to an open-throat wind tunnel, but uses water for the working fluid. Results are given of tests of the tunnel and also of some observations made with model airfoils in the tunnel to study the phenomena of cavitation. It is concluded that a water tunnel does not offer a convenient method of making aerodynamic investigations at large scales. A large diameter water tunnel would be of value chiefly for use in the study of cavitation.






















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.
