Wind Tunnel Design for Wind Turbines
2021Die weltweit steigende Anzahl an Windkraftwerken beschert der Weiterentwicklung an Windturbinen ebenfalls einen großen Aufschwung. Obwohl computerunterstützte Simulationsmethoden wie CFD (Computational Fluid Dynamics) einen wichtigen Beitrag zur Erprobung von Windturbinen leisten, sind experimentell bestimmte Ergebnisse in diesem Bereich unerlässlich ...

The Eiffel Tower was built for the Paris Exposition of 1889. By 1903, Gustave Eiffel had become interested in the new subject of aerodynamics. In that year, he rigged up a cable from the second floor of the tower to the ground. Test objects could be dropped along the cable, and their reaction to wind resistance could be measured.

Wind Tunnels: Design Considerations in Wind Tunnel Testing of Cyclists
2019This chapter describes and summarizes design considerations required to develop an accurate and repeatable wind tunnel-based testing program to measure and optimize the aerodynamic drag of athletes, their apparel, and competition equipment. The chapter focuses on drag measurement techniques for the sport of road cycling with the intent that similar ...

THE subject of turbulence is one of great interest in the field of aerodynamics, and many investigations are in progress in the aerodynamical laboratories of the world on various aspects of the subject. The recent international co‐operative measurements inaugurated under the auspices of the National Physical Laboratory of Great Britain have shown that ...

Towards the virtual wind tunnel
2017The maturity of numerical techniques both in Computational Structural and Fluid Dynamics, accompanied by the availability of affordable high-performance hardware, allows the use of virtual rapid-prototyping facilities as realistic alternatives to traditional wind tunnel experiments.

BEFORE proceeding to the results of the experimental work done in sand moving under controlled conditions through a wind tunnel, it may be of interest to describe shortly the final form of the tunnel with which the work was carried out. The design had to fulfil a number of special requirements, and as no previous experimental work on the subject had ...
