STUDY ON FLOW IN THE VICINITY OF ROTOR BLADE OF HORIZONTAL AXIS WIND TURBINE UNDER OPERATION

抄録

The performance of the wind turbine blade is made improved by using the performance of the two dimensional cross-section. The actual flow field around the blade is complicated by three-dimensional flow in which the flow in the blade span direction also exists. Therefore, as one of the better blade-design methods, the development of blades considering three-dimensional flow is necessary. However, the details of the flow field around the wind turbine blade under operation are still unknown. In this study, the flow field around a wind turbine in a wind tunnel is measured using Laser Doppler Velocimetry.
