A computer-controlled wind tunnel
Journal of Wind Engineering and Industrial Aerodynamics, 1993Abstract Many types of meteolorogical, environmental and boundary layer wind tunnels have been constructed to simulate atmospheric phenomena on buildings, structures and transport of air pollutants. New types of 2 and 3-dimensional wind tunnels have been constructed in our laboratory, which has multi-fans controlled by a computer.

Wind Tunnel Rotor Measurements
2022Wind tunnels have been used extensively by the wind energy community to measure 2D airfoil performance (the subject of 2d Airfoil Measurements). However, despite their size limitations, wind tunnels have also been used for 3D rotating measurements.

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.

The wind channel and the whirling arm have been devised and perfected over a period of a number of years with a view to providing reliable aerodynamic data for aircraft designers. Of late years the wind channel has been used considerably more than the whirling arm.In the two pieces of apparatus distinct methods are used.

Contraction Cone for a Wind Tunnel
Journal of the Aeronautical Sciences, 1943HSTJE-SHEN TSIEN 1 has given a method for designing x i —. e(/') ^ ^ contraction cones for wind tunnels. This is t a n ^ ~ = ^ i e-^x/a) = 1 + 2 / j(— l) e quite accuiate theoretically but requires complicated m=l numerical calculations. A different solution is given f or 0 < ^ < oo below.

An environmental wind tunnel for producing air flow over an automotive vehicle includes a source of air under pressure and an elongated housing for receiving an automotive vehicle. The environmental wind tunnel has an upstream end coupled to the downstream end of the source of air under pressure, so that air is blown axially through the housing from ...
