    Abstract

    The results of experimental research on the wake and induced incoming flow on a vertical axis wind turbine (VAWT) in skew are presented. The previous research on VAWTs in skew is limited since this operation mode has only been found too be significant until now in the operation of VAWTs in the built environment. The published results contain hotwire measurements in the incoming flow and the wake of the VAWT for non-skewed and skewed flow. Due to the high sampling rate, the data allows the effects of blade passing to be identified. Flow visualization of the tip vortices is also presented. Thrust measurements of the rotor were performed in order to understand the effect of skew in thrust variation and to compare with analytical predictions.
