A knowledge of the flow structure in the wake of a wind turbine is important in the design of arrays of units to be used in wind-farm applications. In order to better understand this structure, an experimental program to measure the wake structure downwind of a 17m Darrieus vertical-axis wind turbine was completed. Mean-velocity deficits have been measured as a function of tip-speed ratio and incident wind direction for several downstream locations. The results will allow verification and modification of existing models and improve the capability to predict performance of clusters of wind turbines.
