Wind Tunnels: Uses and Developments by Zied Driss Pdf

Wind tunnels are facilities in which the wind is produced by fans or by compressed air to study and measure the action of the air flow around a solid. There are two basic types of wind tunnels: the closed-circuit and the open-circuit. Open-circuits draw air from the ambient environment and exhaust it back to the ambient after exiting the fan, while in closed-circuit, the air repeatedly circulates through the tunnel. The closed-circuit design delivers improved efficiency and generates less noise, but it is more expensive and more difficult to manufacture. Wind tunnels are typically used in aerodynamic research to analyse the behaviour of flows under varying conditions, both within channels and over solid surfaces. The present book focus on uses and developments of wind tunnels. It consists on nine chapters presenting different studies on the design, uses and developments of the wind tunnel in different applications like wind turbines, building and aircraft models. The presented case studies and development approaches aim to provide the readers, such as engineers and PhD students, with basic and applied studies broadly related to the wind tunnels and its applications.

The Peenemünde Wind Tunnels by Peter P. Wegener Pdf

In 1943, on orders from the German Air Ministry, young physicist Peter P. Wegener left the Russian front and reported to the Baltic village of Peenemünde. His assignment was to work at the supersonic wind tunnels of the rocket laboratories of the German Army. Here Wernher von Braun led a team that developed the V-2, the world's first large rocket-powered guided missile, and laid much of the groundwork for postwar rocket development. In this fascinating book, Wegener recounts his experiences during Hitler's time, World War II, and his years at Peenemünde. He tells how he was working one night in August 1943 when the Allies bombed the laboratories, but left the wind tunnels undamaged. The tunnels were moved to Bavaria, and Wegener was ordered to follow in 1944. After the war, the tunnels were moved again--this time to the United States, accompanied by the author and other German scientists. Shortly before the end of the war, Wegener visited Germany's underground V-2 production plant to retrieve archival material on aerodynamics that had been stored in caves for safekeeping. He describes the appalling history of the concentration camps where SS guards watched over inmates who toiled underground in inhuman conditions and often did not survive. A photoessay enhances this remarkable memoir.

On Improvement of Air Flow in Wind Tunnels by C. Wieselsberger Pdf

The most important aerodynamical qualities that should be aimed at in wind tunnel design, are as follows: 1) constant and parallel direction of flow; 2) uniform velocity across all sections; 3) absence of turbulent motion; 4) constant velocity of flow. The above-mentioned qualities are all realized in a high degree in the Gottingen type of wind tunnel, with a parallel portion before the working section, the cross section of which is steadily reduced. It is shown in what follows, that the system can be applied to other wind tunnels, such as the N.P.L. or Eiffel type.

Experimental Aerodynamics by Bruno Chanetz,Jean Délery,Patrick Gilliéron,Patrick Gnemmi,Erwin R. Gowree,Philippe Perrier Pdf

This book presents experimental techniques in the field of aerodynamics, a discipline that is essential in numerous areas, such as the design of aerial and ground vehicles and engines, the production of energy, and understanding the wind resistance of buildings. Aerodynamics is not only concerned with improving the performance and comfort of vehicles, but also with reducing their environmental impact. The book provides updated information on the experimental and technical methods used by aerodynamicists, engineers and researchers. It describes the various types of wind tunnels – from subsonic to hypersonic – as well as the problems posed by their design and operation. The book also focuses on metrology, which has allowed us to gain a detailed understanding of the local properties of flows, and examines current developments toward creating a methodology combining experiments and numerical simulations: the computer-assisted wind tunnel. Lastly, it offers an overview of experimental aerodynamics based on a prospective vision of the discipline, and discusses potential futures challenges. The book can be used as a textbook for graduate courses in aerodynamics, typically offered to students of aerospace and mechanical engineering programs, and as a learning tool for professionals and engineers in the fields of aerodynamics, aeronautics and astronautics automobile.
