| 内容記述 | In this research a numerical investigation of the effect of winglets on a blade performance for wind turbine is performed. Wind turbine blade from NREL Phase VI was chosen for the investigation. Winglet parameters of a cant angle, height, and winglet tip thickness are applied to investigate the effect on the blade aerodynamic performance. Numerical simulation with RANS equations in combination with SST k-𝜔𝜔 turbulence model was performed. Moving reference frame was applied to simulate the blade rotating motion. The present numerical solutions were compared with the experimental data from NREL phase VI for validation. The comparison showed the solutions were in a good agreement with the experimental data for baseline blade configuration. Wind velocities in range of 8-10 m/s were chosen to investigate the winglet effect. Winglet height was varied to 1.5%, 3%, and 5% of rotor radius while combined with 90° cant angles (Upstream configuration) and -90° (Downstream configuration). Furthermore, winglet tip thickness was reduced from 100% to 85% and 70%. The numerical results showed that the winglet with height 3% of rotor radius and combined with a 90° cant angle has the best power coefficient improvement. Winglet with a -90° cant angle mostly reduces the blade performance. Reducing the winglet tip thickness reduces the strength of the tip vortices behind the blade tip. | |||||||
