EXPERIMENTAL STUDY ON LOAD IMPACT ACTING ON STRAIGHT-BLADED VERTICAL AXIS WIND TURBINE

抄録

The angle of attack of the blades and the Reynolds number of the Vertical Axis Wind Turbine (VAWT) vary greatly depending on the azimuth angle. Also, the flow passing through the downstream blade is complicated as it is disturbed by the blade passing through the upstream and the rotor shaft. Therefore, the load acting on the VAWT is much complicated and fluctuates largely during rotation. In this study, wind tunnel experiments were conducted to clarify the load acting on the VAWT.
