抄録

In order to investigate the aerodynamic characteristics of Wind Turbine Generator, in this study, the pressure characteristic of Wind Turbine Blade, MF-073 is observed by wind tunnel tests, focus on Reynolds Number Effect and turbulence intensity effect. As a result, only in smooth flow, the transition of flow around the Blade involved by changing Reynolds Number is verified. Furthermore, it is obtained that flow around the Blade depend on hysteresis of attacking angle in transition Reynolds Number range.
