Experimental study on sectional performance of horizontal axis wind turbine at optimum operation by using LDV system

In the present, we are trying to find alternative energy to replace fossil fuels. Wind power is a good choice as alternative energy. Wind power produces the electricity without producing greenhouse gases or other pollutants. Wind power is converted to electricity by using wind turbines. The performance of wind turbine generator depends on the rotor blade shape. Generally, sectional performance in axial and tangential flow directions is used to design rotor blades. The designed sectional flow is different from actual one with span-wise flow. For this reason, this study would like to study sectional performance in three dimensional directions for the wind turbine rotor blades, designed by including span-wise flow effect in the future. A model wind turbine with 2.4 m diameter is tested in the large wind tunnel. The velocity filed, count number of local velocity, and standard deviation of velocity in three dimensions are discussed.
