Lidars for Wind Tunnels - an IRPWind Joint Experiment Project [PDF]
Energy Procedia, 2017 Measurement campaigns with continuous-wave Doppler Lidars (Light detection and ranging) developed at DTU Wind Energy in Denmark were performed in two very different wind tunnels. Firstly, a measurement campaign in a small icing wind tunnel chamber at VTT in Finland was performed with high frequency measurements for increasing the understanding of the ...

Validity and Reliability of an On‐Bike Sensor System for the Determination of Aerodynamic Drag in Cycling [PDF]
European Journal of Sport ScienceCycling performance is strongly influenced by aerodynamics, with most resistive drag forces being attributed to the rider. The Body Rocket device (BR) is an on‐bike sensor system that uses the same load cell technology as a wind tunnel, directly ...

Reproducing the Bolund experiment in wind tunnel [PDF]
Wind Energy, 2013 ABSTRACTThe Bolund experiment has been reproduced in a neutral boundary layer wind tunnel (WT) at scale 1:115 for two Reynolds numbers. All the results have been obtained for an incoming flow from the 270owind direction (transectBin the Bolund experiment jargon).

Research progress on the wind tunnel experiment of a bionic flapping-wing aerial vehicle
工程科学学报, 2022 “Flapping wing” is a mechanism observed in the flight of birds, insects, and bats. The lift and thrust for a flight are generated by the active movement of wings. It was first specifically designed by Da Vinci.

Evaluation of off-site effects of wind-eroded sediments especially the content of pesticides [PDF]
Geographica Pannonica, 2022 Wind-eroded sediment, as an environmental transport pathway of toxic elements and pesticids, can result in environmental and human exposure far beyond the agricultural areas where it has been applied.

Scaling of wind turbine aerodynamics: wind tunnel experiments [PDF]
MATEC Web of Conferences, 2020 A small-scale wind turbine model was designed and manufactured to study its aerodynamic thrust force and the harvested flow energy. To provide a good understanding of the aerodynamics of the small-scale wind turbine at the low Reynolds number, the performance of three different types of blade airfoils was studied.
