Abstract: Abstract:This study explores the effects of different arrangements such as side-by-side and tandem in wind turbine towers under various Reynolds numbers. The Reynolds number was changed from 1.2×103 to 4×106. The wake-flow behaviors, velocity characteristics, and wake vortex shedding were studied. The effects of side-by-side gap ratio (G*) and tandem gap ratio (L*) were considered. Smoke-wire flow visualization technique was used to render the flow characteristics. At different heights, the flow characteristics were observed in four sections: the blade at tower top, bluff body of blade and generator, cylinder of wind turbine tower, and junction at the bottom. A hot-wire anemometer was used to measure the vortex-street frequency. The characteristic flow modes for the side-by-side configuration are the anti- and in-phase vortex modes, and those for the tandem arrangement are the single, attached, and bi-vortex modes. For side-by-side wind towers, the wake flow field behaved like that of single one when G*> 1.0. For tandem wind turbine towers, the flow behaviors are independent when L*> 0.85.
