Abstract

The wind-speed at a site can be measured by installing anemometers on top of meteorological (met) towers. Accelerated airflow, or speed-up, around the top of met towers can cause incorrect anemometer measurements. We consider a particular example where an anemometer was located only 2% tower diameters above the met tower. Using a standard computational fluid dynamics package, we found the maximum error for this of the wind-speed. We conclude that a top-mounted anemometer should be located at the windward side of its met tower, raised 5 diameters above the top. This will reduce speed-up error to less than 1% NOTE: This Paper was first referred and pubblished by E-WindEng, then submitted and accepted for Pubblication by Applied Energy
