The wind tunnel tests have been widely used for wind resistant design of bridges, because they can provide reliable information on the wind-induced forces and responses of bridges. In this chapter, types of wind tunnel tests for wind resistant design of bridges will be listed and their brief explanations will be given first.

Cycling Aerodynamics: Wind Tunnel Testing versus Track Testing
2010This paper deals with the aerodynamics of time trial cycling, presenting a reasoned comparison between the results obtained from cyclists wind tunnel testis and track tests carried out in an indoor facility. The paper outlines the difference between the two kinds of tests and the indications that can be extracted from the results.

Free-Tip Rotor Wind Tunnel Test Results
Journal of the American Helicopter Society, 1986Seven controller mechanisms and several tip geometries were proposed and evaluated in the course of a free tip rotor development program which integrated those components into a model rotor system for wind tunnel testing. After a rigid whirl test was run to determine controller mechanism performance and structural integrity, a second whirl test was ...

Uncertainty Identification of Supersonic Wind-Tunnel Testing
Journal of Aircraft, 2010In this study, a methodology for the identification of uncertainty of supersonic wind tunnel testing is developed. Instead of conventional multi-tunnel testing, multi-position testing is performed across the characteristic net of supersonic flow. From the variations in aerodynamic coefficients in body axes, the uncertainty caused by flow quality is ...

More Photogrammetry for Wind-Tunnel Testing
AIAA Journal, 2002Recent work by Liu et al. has led to renewed interest in the use of photogrammetry for measuring the position, attitude, and deformation of a test article in a wind tunnel. The present research expands on this work with a more comprehensive mathematical model that can be used not only for determining the interior parameters of the cameras, but also the

Wind tunnel testing of wake control strategies
2016 American Control Conference (ACC), 2016Goal of this paper is to present results from wind tunnel tests aimed at evaluating the potential of different wake control strategies for wind farm power maximization and load reduction. The experiments are conducted in a large boundary layer wind tunnel, using up to six servo-actuated and highly sensorized wind turbine scaled models in different wind

Hypersonic Wind Tunnel Testing
1992In general, there are four primary reasons for wind tunnel testing: 1. understanding aerodynamic flow (research) 2. development of a database 3. parametric configuration studies and 4.
